Afzal Mohammed 130142d914 ARM: OMAP2+: hwmod: rt address space index for DT
Address space is being removed from hwmod database and DT information
in <reg> property is being used. Currently the 0th index of device
address space is used to map for register target address. This is not
always true, eg. cpgmac has it's sysconfig in second address space.

Handle it by specifying index of device address space to be used for
register target. As default value of this field would be zero with
static initialization, existing behaviour of using first address space
for register target while using DT would be kept as such.

Rajendra Nayak 7268032dfb ARM: OMAP2+: Sync hwmod state with the pm_runtime and omap_device state
Some hwmods which are marked with HWMOD_INIT_NO_IDLE are left in enabled
state post setup(). When a omap_device gets created for such hwmods
make sure the omap_device and pm_runtime states are also in sync for such
hwmods by doing a omap_device_enable() and pm_runtime_set_active() for the
device.

Rajendra Nayak f66e329d88 ARM: OMAP2+: Avoid idling memory controllers with no drivers
Memory controllers in OMAP (like GPMC and EMIF) have the hwmods marked with
HWMOD_INIT_NO_IDLE and are left in enabled state post initial setup.

Even if they have drivers missing, avoid idling them as part of
omap_device_late_idle()

Rajendra Nayak 7dedd34694 ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL
With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+:
Fix serial init for device tree based booting" stubbing out
omap_serial_early_init() for Device tree based booting, there was a
crash observed on AM335x based devices when hwmod does a
_setup_reset() early at boot.

This was rootcaused to hwmod trying to reset console uart while
earlycon was using it.  The way to tell hwmod not to do this is to
specify the HWMOD_INIT_NO_RESET flag, which were infact set by the
omap_serial_early_init() function by parsing the cmdline to identify
the console device.

Parsing the cmdline to identify the uart used by earlycon itself seems
broken as there is nothing preventing earlycon to use a different one.

This patch, instead, attempts to populate the requiste flags for hwmod
based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need
for cmdline parsing in the DT as well as non-DT cases to identify the
uart used by earlycon.

Nishanth Menon bd3c5544a1 ARM: dts: omap5-uevm: update optional/unused regulator configurations
commit e00c27ef3b
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.

However, The regulator information is based on an older temporary
pre-production board variant and does not reflect production board
750-2628-XXX boards.

The following optional/unused regulators can be updated:

- SMPS9 supplies TWL6040 over VDDA_2v1_AUD. This regulator needs to be
enabled only when audio is active. Since it does not come active by
default, it does not require "always-on" or "boot-on".

- LDO2 and LDO8 do not go to any peripheral or connector on the board.
Further, these unused regulators should have been 2.8V for LDO2 and
3.0V for LDO8. Mark these LDOs as disabled in the dts until needed.

Nishanth Menon e18235a62a ARM: dts: omap5-uevm: fix regulator configurations mandatory for SoC
commit e00c27ef3b
(ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes)
introduced regulator entries for OMAP5uEVM.

However, The regulator information is based on an older temporary
pre-production board variant and does not reflect production board
750-2628-XXX boards.

The following fixes are hence mandatory to ensure right voltage is
supplied to key OMAP5 SoC voltage rails:

- LDO1 supplies VDDAPHY_CAM which is OMAP5's vdda_csiporta/b/c. This
can only be supplied at 1.5V or 1.8V and we currently supply 2.8V.

To prevent any potential device damage risk, use the specified
1.5V-1.8V supply.

Remove 'always-on' and 'boot-on' settings here as it is
a 'on need' supply to SoC IP and is not enabled by PMIC by
default at boot.

- LDO3 supplies Low Latency Interface(LLI) hardware module which is a
special hardware to communicate with Modem. However since uEVM is
not setup by default for this communication, this should be disabled
by default.

Further, vdda_lli is supposed to be 1.5V and not 3V.

- LDO4 supplies VDDAPHY_DISP which is vdda_dsiporta/c/vdda_hdmi

This can only be supplied at 1.5V or 1.8V and we currently
supply 2.2V.

To prevent any potential device damage risk, use the specified
1.5V-1.8V supply.

Remove 'always-on' and 'boot-on' settings here as it is a 'on need'
supply to SoC IP and is not enabled by PMIC by default at boot.

- LDO6 supplies the board specified VDDS_1V2_WKUP supply going to
ldo_emu_wkup/vdds_hsic. To stay within the SoC specification supply
1.2V instead of 1.5V.

- LDO7 supplies VDD_VPP which is vpp1. This is currently configured for
1.5V which as per data manual "A pulse width of 1000 ns and an amplitude
of 2V is required to program each eFuse bit. Otherwise, VPP1 must not
be supplied".

So, fix the voltage to 2V. and disable the supply since we have no plans
of programming efuse bits - it can only be done once - in factory.

Further it is not enabled by default by PMIC so, 'boot-on' must be
removed, and the 'always-on' needs to be removed to achieve pulsing
if efuse needs to be programmed.

- LDO9 supplies the board specified vdds_sdcard supply going within SoC
specification of 1.8V or 3.0V. Further the supply is controlled by
switch enabled by REGEN3. So, introduce REGEN3 and map sdcard slot to
be powered by LDO9. Remove 'always-on' allowing the LDO to be disabled
on need basis.

commit e00c27ef3b

introduced regulator entries for OMAP5uEVM.

However, currently we use the Palmas regulator names which is used for
different purposes on uEVM. Document the same based on 750-2628-XXX
boards - which is meant to be supported by this dts.

The find_next_bit_left function is broken if used with an offset which
is not a multiple of 64. The shift to mask the bits of a 64-bit word
not to search is in the wrong direction, the result can be either a
bit found smaller than the offset or failure to find a set bit.

Will Deacon acfdd4b1f7 ARM: 7791/1: a.out: remove partial a.out support
a.out support on ARM requires that argc, argv and envp are passed in
r0-r2 respectively, which requires hacking load_aout_binary to
prevent argc being clobbered by the return code. Whilst mainline kernels
do set the registers up in start_thread, the aout loader has never
carried the hack in mainline.

Initialising the registers in this way actually goes against the libc
expectations for ELF binaries, where argc, argv and envp are passed on
the stack, with r0 being used to hold a pointer to an exit function for
cleaning up after the dynamic linker if required. If the pointer is
NULL, then it is ignored. When execing an ELF binary, Linux currently
zeroes r0, then sets it to argc and then finally clobbers it with the
return value of the execve syscall, so we actually end up with:

	r0 = 0
	stack[0] = argc
	r1 = stack[1] = argv
	r2 = stack[2] = envp

libc treats r1 and r2 as undefined. The clobbering of r0 by sys_execve
works for user-spawned threads, but when executing an ELF binary from a
kernel thread (via call_usermodehelper), the execve is performed on the
ret_from_fork path, which restores r0 from the saved pt_regs, resulting
in argc being presented to the C library. This has horrible consequences
when the application exits, since we have an exit function registered
using argc, resulting in a jump to hyperspace.

This patch solves the problem by removing the partial a.out support from
arch/arm/ altogether.

Catalin Marinas bdae73cd37 ARM: 7790/1: Fix deferred mm switch on VIVT processors
As of commit b9d4d42ad9 (ARM: Remove __ARCH_WANT_INTERRUPTS_ON_CTXSW on
pre-ARMv6 CPUs), the mm switching on VIVT processors is done in the
finish_arch_post_lock_switch() function to avoid whole cache flushing
with interrupts disabled. The need for deferred mm switch is stored as a
thread flag (TIF_SWITCH_MM). However, with preemption enabled, we can
have another thread switch before finish_arch_post_lock_switch(). If the
new thread has the same mm as the previous 'next' thread, the scheduler
will not call switch_mm() and the TIF_SWITCH_MM flag won't be set for
the new thread.

This patch moves the switch pending flag to the mm_context_t structure
since this is specific to the mm rather than thread.

Fabio Estevam 1f49856bb0 ARM: 7789/1: Do not run dummy_flush_tlb_a15_erratum() on non-Cortex-A15
Commit 93dc688 (ARM: 7684/1: errata: Workaround for Cortex-A15 erratum 798181 (TLBI/DSB operations)) causes the following undefined instruction error on a mx53 (Cortex-A8):

Internal error: Oops - undefined instruction: 0 [#1] SMP ARM

PC is at check_and_switch_context+0x17c/0x4d0
LR is at check_and_switch_context+0xdc/0x4d0

This problem happens because check_and_switch_context() calls dummy_flush_tlb_a15_erratum() without checking if we are really running on a Cortex-A15 or not.

To avoid this issue, only call dummy_flush_tlb_a15_erratum() inside
check_and_switch_context() if erratum_a15_798181() returns true, which means that we are really running on a Cortex-A15.

Pull powerpc fixes from Ben Herrenschmidt:
 "Here is a series of powerpc fixes.  It's a bit big, mostly because of
  the series of 11 "EEH" patches from Gavin.  The EEH (Our IBM specific
  PCI/PCIe Enhanced Error Handling) code had been rotting for a while
  and this merge window saw a significant rework & fixing of it by Gavin
  Shan.

  However, that wasn't complete and left some open issues.  There were
  still a few corner cases that didn't work properly, for example in
  relation to hotplug and devices without explicit error handlers.  We
  had some patches but they weren't quite good enough yet so I left them
  off the 3.11 merge window.

  Gavin since then fixed it all up, we ran quite a few rounds of testing
  and it seems fairly solid (at least probably more than it has ever
  been).  This should probably have made -rc1 but both Gavin and I took
  some vacation so it had to wait for -rc2.

  The rest is more bug fixes, mostly to new features recently added, for
  example, we missed the cpu table entry for one of the two models of P8
  (we didn't realize they had different PVR [Processor Version Register]
  values), some module CRC issues, etc..."

Sachin Kamat 53302bf60d ARM: EXYNOS: Update CONFIG_ARCH_NR_GPIO for Exynos
With the recent cleanup in Exynos platform code notably commits
17859bec ("ARM: EXYNOS: Do not select legacy Kconfig symbols any

of ARCH_NR_GPIOS got removed. This started causing problems on SoCs like
Exynos4412 which have more than the default number of GPIOs. Thus define
this number in KConfig file which takes care of current SoC requirements
and provides scope for GPIO expanders. Without this patch we get the
following errors during boot:

Its because exynos[4/5]_map_io() function ioremaps a single 512KB memory

debug_ll_io_init(), called earlier in exynos_init_io().

This patch removes iodesc entries for UART controller for all Samsung SoC's,
since now the Samsung uart driver does a ioremap during probe and any needed
iomapping for earlyprintk will be handled by debug_ll_io_init().

Anshuman Khandual 7689bdcab1 powerpc/perf: Ignore separate BHRB privilege state filter request
Completely ignore BHRB privilege state filter request as we are
already configuring that with privilege state filtering attribute
for the accompanying PMU event. This would help achieve cleaner
user space interaction for BHRB.

This patch fixes a situation like this

Before patch:-
------------
./perf record -j any -e branch-misses:k ls
Error:
The sys_perf_event_open() syscall returned with 95 (Operation not
supported) for event (branch-misses:k).
/bin/dmesg may provide additional information.
No CONFIG_PERF_EVENTS=y kernel support configured?

Here 'perf record' actually copies over ':k' filter request into BHRB
privilege state filter config and our previous check in kernel would
fail that.

After patch:-

Sylwester Nawrocki d817468c4b ARM: S3C24XX: Add missing clkdev entries for s3c2440 UART
This patch restores serial port operation which has been broken since
commit 60e9357547 ("serial: samsung: enable clock before clearing
pending interrupts during init")

That commit only uncovered the real issue which was missing clkdev
entries for the "uart" clocks on S3C2440. It went unnoticed so far
because return value of clk API calls were not being checked at all
in the samsung serial port driver.

This patch should be backported to at least 3.10 stable kernel, since
the serial port has not been working on s3c2440 since 3.10-rc5.

Gavin Shan f5c57710dd powerpc/eeh: Use partial hotplug for EEH unaware drivers
When EEH error happens to one specific PE, some devices with drivers
supporting EEH won't except hotplug on the device. However, there
might have other deivces without driver, or with driver without EEH
support. For the case, we need do partial hotplug in order to make
sure that the PE becomes absolutely quite during reset. Otherise,
the PE reset might fail and leads to failure of error recovery.

The current code doesn't handle that 'mixed' case properly, it either
uses the error callbacks to the drivers, or tries hotplug, but doesn't
handle a PE (EEH domain) composed of a combination of the two.

The patch intends to support so-called "partial" hotplug for EEH:
Before we do reset, we stop and remove those PCI devices without
EEH sensitive driver. The corresponding EEH devices are not detached
from its PE, but with special flag. After the reset is done, those
EEH devices with the special flag will be scanned one by one.

Gavin Shan ab444ec97e powerpc/pci: Partial tree hotplug support
When EEH error happens to one specific PE, the device drivers
of its attached EEH devices (PCI devices) are checked to see
the further action: reset with complete hotplug, or reset without
hotplug. However, that's not enough for those PCI devices whose
drivers can't support EEH, or those PCI devices without driver.
So we need do so-called "partial hotplug" on basis of PCI devices.
In the situation, part of PCI devices of the specific PE are
unplugged and plugged again after PE reset.

The patch changes pcibios_add_pci_devices() so that it can support
full hotplug and so-called "partial" hotplug based on device-tree
or real hardware. It's notable that pci_of_scan.c has been changed
for a bit in order to support the "partial" hotplug based on dev-tree.

Most of the generic code already supports that, we just need to
plumb it properly on our side.

However, we need to keep it if the hotplug an artifial one caused by

Since we remove EEH device through the PCI hook pcibios_release_device(),
the flag "purge_pe" passed to various functions is meaningless. So the patch
removes the meaningless flag and introduce new flag "EEH_PE_KEEP"

Anton Blanchard 0e0ed6406e powerpc/modules: Module CRC relocation fix causes perf issues
Module CRCs are implemented as absolute symbols that get resolved by
a linker script. We build an intermediate .o that contains an
unresolved symbol for each CRC. genksysms parses this .o, calculates
the CRCs and writes a linker script that "resolves" the symbols to
the calculated CRC.

Unfortunately the ppc64 relocatable kernel sees these CRCs as symbols
that need relocating and relocates them at boot. Commit d4703aef
(module: handle ppc64 relocating kcrctabs when CONFIG_RELOCATABLE=y)
added a hook to reverse the bogus relocations. Part of this patch
created a symbol at 0x0:

# head -2 /proc/kallsyms
0000000000000000 T reloc_start
c000000000000000 T .__start

This reloc_start symbol is causing lots of confusion to perf. It
thinks reloc_start is a massive function that stretches from 0x0 to
0xc000000000000000 and we get various cryptic errors out of perf,
including:

problem incrementing symbol count, skipping event

This patch removes the  reloc_start linker script label and instead
defines it as PHYSICAL_START. We also need to wrap it with
CONFIG_PPC64 because the ppc32 kernel can set a non zero
PHYSICAL_START at compile time and we wouldn't want to subtract
it from the CRCs in that case.

Mike Frysinger 6287e73198 ARM: footbridge: fix overlapping PCI mappings
Commit 8ef6e6201b (ARM: footbridge: use
fixed PCI i/o mapping) broke booting on my netwinder.  Before that,
everything boots fine.  Since then, it crashes on boot.

With earlyprintk, I see it BUG-ing like so:
kernel BUG at lib/ioremap.c:27!
Internal error: Oops - BUG: 0 [#1] ARM
...

...

Russell points out it's because of overlapping PCI mappings that was
added with the aforementioned commit.  Rob thought the code would re-use
the static mapping, but that turns out to not be the case and instead
hits the BUG further down.

After deleting this hunk as suggested by Russel, the system boots up fine
again and all my PCI devices work (IDE, ethernet, the DC21285).

Commit a469abd0f8 ("ARM: elf: add new hwcap for identifying atomic
ldrd/strd instructions") added a new hwcap to identify LPAE on CPUs
which support it. Whilst the hwcap data is correct, the string reported
in /proc/cpuinfo actually matches on HWCAP_VFPD32, which was missing
an entry in the string table.

This patch fixes this problem by adding a "vfpd32" string at the correct
offset, preventing us from falsely advertising LPAE on CPUs which do not
support it.

Mark Rutland b60d5db690 ARM: 7786/1: hyp: fix macro parameterisation
Currently, compare_cpu_mode_with_primary uses a mixture of macro
arguments and hardcoded registers, and does so incorrectly, as it
stores (__boot_cpu_mode_offset | BOOT_CPU_MODE_MISMATCH) to
(__boot_cpu_mode + &__boot_cpu_mode_offset), which could corrupt an
arbitrary portion of memory.

This patch fixes up compare_cpu_mode_with_primary to use the macro
arguments, correctly updating __boot_cpu_mode.

Russell King c65b7e98b4 ARM: 7785/1: mm: restrict early_alloc to section-aligned memory
When map_lowmem() runs, and processes a memory bank whose start or end
is not section-aligned, memory must be allocated to store the 2nd-level
page tables. Those allocations are made by calling memblock_alloc().

At this point, the only memory that is free *and* mapped is memory which
has already been mapped by map_lowmem() itself. For this reason, we must
calculate the first point at which map_lowmem() will need to allocate
memory, and set the memblock allocation limit to a lower address, so that
memblock_alloc() is guaranteed to return memory that is already mapped.

This patch enhances sanity_check_meminfo() to calculate that memory
address, and pass it to memblock_set_current_limit(), rather than just
assuming the limit is arm_lowmem_limit.

The algorithm applied is:

* Default memblock_limit to arm_lowmem_limit in the absence of any other
  limit; arm_lowmem_limit is the highest memory that is mapped by
  map_lowmem().

* While walking the list of memblocks, if the start of a block is not
  aligned, 2nd-level page tables will need to be allocated to map the
  first few pages of the block. Hence, the memblock_limit must be before
  the start of the block.

* Similarly, if the end of any block is not aligned, 2nd-level page
  tables will need to be allocated to map the last few pages of the
  block. Hence, the memblock_limit must point at the end of the block,
  rounded down to section-alignment.

* The memory blocks are assumed to be sorted in address order, so the
  first unaligned block start or end is used to set the limit.

With this algorithm, the start or end of almost any bank can be non-
section-aligned. The only exception is that the start of bank 0 must
be section-aligned, since otherwise memory would need to be allocated
when mapping the start of bank 0, which occurs before any free memory
is mapped.

Commit ae8a8b9553 ("ARM: 7691/1: mm: kill unused TLB_CAN_READ_FROM_L1_CACHE

cache flushing operations on ARMv7 SMP CPUs.

Unfortunately, when targetting Thumb-2, these `mov pc, lr' sequences
assemble to 2 bytes which can lead to corruption of the instruction
stream after code patching.

This patch fixes the alternates to use wide (32-bit) instructions for
Thumb-2, therefore ensuring that the patching code works correctly.

Russell King b6992fa9a7 ARM: document DEBUG_UNCOMPRESS Kconfig option
This non-user visible option lacked any kind of documentation.  This
is quite common for non-user visible options; certian people can't
understand the point of documenting such options with help text.

However, here we have a case in point: developers don't understand the
option either, as they were thinking that when the option is not set,
the decompressor should produce no output what so ever.  This is
incorrect, as the purpose of this option is to control whether a
multiplatform kernel uses the kernel debugging macros to produce
output or not.

So let's document this via help rather than commentry to prevent others
falling into this misunderstanding.

Chen Gang 91b678c8ed alpha: kernel: typo issue, using '1' instead of '11'
For sending message:

        *(unsigned int *)&cpu->ipc_buffer[0] = len;
        cp1 = (char *) &cpu->ipc_buffer[1];

But for receive message:

                cnt = cpu->ipc_buffer[0] >> 32;
                ...
                       cp1 = (char *) &cpu->ipc_buffer[11];

They are not pairs, it is typo issue of the redundency '1'.

So need use '1' instead of '11'.

When sending message in send_secondary_console_msg(), the length is not

When receive message in recv_secondary_console_msg(), the 'cnt' also

So when get string from ipc_buffer, it may not be NUL terminated.

During the pruning of the device tree octeon_fdt_pip_iface() is called
for each PIP interface and every port up to the port count is removed
from the device tree. However, the count was set to the return value of
cvmx_helper_interface_enumerate() which doesn't actually return the
count but just returns zero on success. This effectively removed *all*
ports from the tree.

Use cvmx_helper_ports_on_interface() instead to fix this. This
successfully restores the 3 ports of my ERLite-3 and fixes the "kernel

the eret to return to the guest code clears the LLbit which makes the sc

Commit 4df715aa ["MIPS: BMIPS: support booting from physical CPU other

released from reset on systems where we boot from TP0. The problem is
that we are checking whether the slave CPU logical CPU map is 0, which
is never true for systems booting from TP0, so we do not release the
slave TP from reset and we are just stuck. Fix this by properly checking
that the CPU we intend to boot really is the physical slave CPU (logical
and physical value being 1).

 "With the __cpuinit infrastructure removed earlier, this group of

  trivial updates.

Nicolas Ferre 69b90f1aad ARM: at91/DT: at91sam9x5ek: fix USB host property to enable port C
Device Tree "num-ports" property of USB host node has to be
set to maximum number of ports available.
The possibility to activate a particular port is done by specifying the proper
gpio configuration for its vbus.

This patch fixes the USB host node by configuring the 3 ports available on the
product and letting "port A" available for USB gadget usage.

Xiao Guangrong 1c118b8226 KVM: MMU: avoid fast page fault fixing mmio page fault
Currently, fast page fault incorrectly tries to fix mmio page fault when
the generation number is invalid (spte.gen != kvm.gen).  It then returns
to guest to retry the fault since it sees the last spte is nonpresent.
This causes an infinite loop.

Since fast page fault only works for direct mmu, the issue exists when
1) tdp is enabled. It is only triggered only on AMD host since on Intel host
   the mmio page fault is recognized as ept-misconfig whose handler call
   fault-page path with error_code = 0

2) guest paging is disabled. Under this case, the issue is hardly discovered
   since paging disable is short-lived and the sptes will be invalid after
   memslot changed for 150 times

Fix it by filtering out MMIO page faults in page_fault_can_be_fast.

Kees Cook 4df05f3619 x86: Make sure IDT is page aligned
Since the IDT is referenced from a fixmap, make sure it is page aligned.
Merge with 32-bit one, since it was already aligned to deal with F00F
bug. Since bss is cleared before IDT setup, it can live there. This also
moves the other *_idt_table variables into common locations.

This avoids the risk of the IDT ever being moved in the bss and having
the mapping be offset, resulting in calling incorrect handlers. In the
current upstream kernel this is not a manifested bug, but heavily patched
kernels (such as those using the PaX patch series) did encounter this bug.

The tables other than idt_table technically do not need to be page
aligned, at least not at the current time, but using a common
declaration avoids mistakes.  On 64 bits the table is exactly one page
long, anyway.

H. Peter Anvin 5ff560fd48 x86, suspend: Handle CPUs which fail to #GP on RDMSR
There are CPUs which have errata causing RDMSR of a nonexistent MSR to
not fault.  We would then try to WRMSR to restore the value of that
MSR, causing a crash.  Specifically, some Pentium M variants would
have this problem trying to save and restore the non-existent EFER,
causing a crash on resume.

Work around this by making sure we can write back the result at
suspend time.

Shawn Guo 4f71612ee3 ARM: imx: fix vf610 enet module clock selection
The fec/enet driver calculates MDC rate with the formula below.

  ref_freq / ((MII_SPEED + 1) x 2)

The ref_freq here is the fec internal module clock, which is missing
from clk-vf610 clock driver right now.  And clk-vf610 driver mistakenly
supplies RMII clock (50 MHz) as the source to fec.  This results in the
situation that fec driver gets ref_freq as 50 MHz, while physically it
runs at 66 MHz (fec module clock physically sources from ipg which runs
at 66 MHz).  That's why software expects MDC runs at 2.5 MHz, while the
measurement tells it runs at 3.3 MHz.  And this causes the PHY KSZ8041
keeps swithing between Full and Half mode as below.

  libphy: 400d0000.etherne:00 - Link is Up - 100/Full
  libphy: 400d0000.etherne:00 - Link is Up - 100/Half

Paul Gortmaker 148f9bb877 x86: delete __cpuinit usage from all x86 files
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
are flagged as __cpuinit  -- so if we remove the __cpuinit from
arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
content into no-ops as early as possible, since that will get rid
of these warnings.  In any case, they are temporary and harmless.

This removes all the arch/x86 uses of the __cpuinit macros from
all C files.  x86 only had the one __CPUINIT used in assembly files,
and it wasn't paired off with a .previous or a __FINIT, so we can
delete it directly w/o any corresponding additional change there.

Linus Torvalds 9663398a09 ARM: SoC fixes for 3.11-rc
This is our first set of fixes from arm-soc for 3.11.
  - A handful of build and warning fixes from Arnd
  - A collection of OMAP fixes
  - defconfig updates to make the default configs more useful for real use
    (and testing) out of the box on hardware.
 
 And a couple of other small fixes. Some of these have been recently
 applied but it's normally how we deal with fixes, with less bake time
 in -next needed.

Dave Hansen baf64b8544 perf/x86: Fix incorrect use of do_div() in NMI warning
I completely botched understanding the calling conventions of
do_div().  I assumed that do_div() returned the result instead
of realizing that it modifies its argument and returns a
remainder.  The side-effect from this would be bogus numbers
for the "msecs" value in the warning messages:

	INFO: NMI handler (perf_event_nmi_handler) took too long to run: 0.114 msecs

Note, there was a second fix posted by Stephane Eranian for
a separate patch which I also botched:

Russell King fa142ff5b3 Watchdog: allow orion_wdt to be built for Dove
The watchdog infrastructure in Dove is no different from that in
Orion5x or Kirkwood, so let's enable it for Dove.  The only things
missing are a few register settings in Dove's bridge-regs.h.

Rather than duplicating the same register bit masks for the RSTOUTn_MASK
and BRIDGE_CAUSE registers, move the definitions into the watchdog
driver itself.

Viresh Kumar 6e63a3a294 watchdog: delete mpcore_wdt driver
Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu
interrupt (usually interrupt #30), and the GIC configuration should flag it as
such. With this setup, request_irq() should fail, and the right API is
request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq().

Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the
right CPU.

There are no users of this driver since a long time and it makes more sense to
get rid of it as nobody is looking to fix it.

In case somebody wakes up after this has been removed and needs it, please
revert this driver and pick these updates (These were never pushed to mainline):

Linus Torvalds 8cbd0eefca Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui:
 "There are not too many changes this time, except two new platform
  thermal drivers, ti-soc-thermal driver and x86_pkg_temp_thermal
  driver, and a couple of small fixes.

  Highlights:

   - move the ti-soc-thermal driver out of the staging tree to the
     thermal tree.

   - introduce the x86_pkg_temp_thermal driver.  This driver registers
     CPU digital temperature package level sensor as a thermal zone.

   - small fixes/cleanups including removing redundant use of
     platform_set_drvdata() and of_match_ptr for all platform thermal
     drivers"
