Ralf Baechle 80fa8181aa MIPS: Delete definition of SA_RESTORER.
SA_RESTORER used to be defined as 0x04000000 but only the O32 ABI ever
supported its use and no libc was using it, so the entire sa-restorer
functionality was removed with lmo commit 39bffc12c3580ab [Zap sa_restorer.]
for 2.5.48 retaining only the SA_RESTORER definition as a reminder to avoid
accidental reuse of the mask bit.

Upstream cdef9602fbf1871a43f0f1b5cea10dd0f275167d [signal: always clear
sa_restorer on execve] adds code that assumes sa_sigaction has an
sa_restorer field, if SA_RESTORER is defined which would break MIPS.
So remove the SA_RESTORER definition before the v3.8.4 merge.

Deng-Cheng Zhu adb3789264 MIPS: Fix ISA level which causes secondary cache init bypassing and more
The commit a96102be70 introduced set_isa() where compatible ISA info is
also set aside from the one gets passed in. It means, for example, 1004K
will have MIPS_CPU_ISA_M32R2/M32R1/II/I flags. This leads to things like
the following inappropriate:

if (c->isa_level == MIPS_CPU_ISA_M32R1 ||
    c->isa_level == MIPS_CPU_ISA_M32R2 ||
    c->isa_level == MIPS_CPU_ISA_M64R1 ||
    c->isa_level == MIPS_CPU_ISA_M64R2)

This patch fixes it.

Paul Bolle 4e1db26a0b ARM: 7690/1: mm: fix CONFIG_LPAE typos
CONFIG_LPAE doesn't exist: the correct option is CONFIG_ARM_LPAE, so fix
up the two typos under arch/arm/.

The fix to head.S is slightly scary, but this is just for setting up
an early io-mapping for the serial port when running on a big-endian,
LPAE system. Since these systems don't exist in the wild (at least, I
have no access to one outside of kvmtool, which doesn't provide a serial
port suitable for earlyprintk), then we can revisit the code later if it
causes any problems.

Will Deacon 6f3d90e556 ARM: 7685/1: delay: use private ticks_per_jiffy field for timer-based delay ops
Commit 70264367a2 ("ARM: 7653/2: do not scale loops_per_jiffy when
using a constant delay clock") fixed a problem with our timer-based
delay loop, where loops_per_jiffy is scaled by cpufreq yet used directly
by the timer delay ops.

This patch fixes the problem in a more elegant way by keeping a private
ticks_per_jiffy field in the delay ops, independent of loops_per_jiffy
and therefore not subject to scaling. The loop-based delay continues to
use loops_per_jiffy directly, as it should.

On Cortex-A15 (r0p0..r3p2) the TLBI/DSB are not adequately shooting down
all use of the old entries. This patch implements the erratum workaround
which consists of:

1. Dummy TLBIMVAIS and DSB on the CPU doing the TLBI operation.
2. Send IPI to the CPUs that are running the same mm (and ASID) as the
   one being invalidated (or all the online CPUs for global pages).
3. CPU receiving the IPI executes a DMB and CLREX (part of the exception
   return code already).

Rob Herring 6e7aceeb7c ARM: 7682/1: cache-l2x0: fix masking of RTL revision numbering and set_debug init
Commit b8db6b8 (ARM: 7547/4: cache-l2x0: add support for Aurora L2 cache
ctrl) moved the masking of the part ID which caused the RTL version to be
lost. Commit 6248d06 (ARM: 7545/1: cache-l2x0: make outer_cache_fns a
field of l2x0_of_data) changed how .set_debug is initialized. Both commits
break commit 74ddcdb (ARM: 7608/1: l2x0: Only set .set_debug
on PL310 r3p0 and earlier) which uses the RTL version to conditionally set
.set_debug function pointer. Commit b8db6b8 also caused the printed cache
ID to be missing the version information.

Fix this by reverting how the part number is masked so the RTL version
info is maintained. The cache-id-part DT property does not set the RTL
bits so masking them should have no effect. Also, re-arrange the order
of the function pointer init so the .set_debug function can be overridden.

Heiko Carstens ea81531de2 s390/uaccess: fix page table walk
When translating user space addresses to kernel addresses the follow_table()
function had two bugs:

- PROT_NONE mappings could be read accessed via the kernel mapping. That is
  e.g. putting a filename into a user page, then protecting the page with
  PROT_NONE and afterwards issuing the "open" syscall with a pointer to
  the filename would incorrectly succeed.

- when walking the page tables it used the pgd/pud/pmd/pte primitives which
  with dynamic page tables give no indication which real level of page tables
  is being walked (region2, region3, segment or page table). So in case of an
  exception the translation exception code passed to __handle_fault() is not
  necessarily correct.
  This is not really an issue since __handle_fault() doesn't evaluate the code.
  Only in case of e.g. a SIGBUS this code gets passed to user space. If user
  space can do something sane with the value is a different question though.

To fix these issues don't use any Linux primitives. Only walk the page tables
like the hardware would do it, however we leave quite some checks away since
we know that we only have full size page tables and each index is within bounds.

In theory this should fix all issues...

Keller, Jacob E 7d4c04fc17 net: add option to enable error queue packets waking select
Currently, when a socket receives something on the error queue it only wakes up
the socket on select if it is in the "read" list, that is the socket has
something to read. It is useful also to wake the socket if it is in the error
list, which would enable software to wait on error queue packets without waking
up for regular data on the socket. The main use case is for receiving
timestamped transmit packets which return the timestamp to the socket via the
error queue. This enables an application to select on the socket for the error
queue only instead of for the regular traffic.

-v2-
* Added the SO_SELECT_ERR_QUEUE socket option to every architechture specific file
* Modified every socket poll function that checks error queue

Mac Lin a3d9052c62 ARM: cns3xxx: fix mapping of private memory region
Since commit 0536bdf33f (ARM: move iotable mappings within the vmalloc
region), the Cavium CNS3xxx cannot boot anymore.

This is caused by the pre-defined iotable mappings is not in the vmalloc
region. This patch move the iotable mappings into the vmalloc region, and
merge the MPCore private memory region (containing the SCU, the GIC and
the TWD) as a single region.

Chris Metcalf ff7f3efb9a tile: expect new initramfs name from hypervisor file system
The current Tilera boot infrastructure now provides the initramfs
to Linux as a Tilera-hypervisor file named "initramfs", rather than
"initramfs.cpio.gz", as before.  (This makes it reasonable to use
other compression techniques than gzip on the file without having to
worry about the name causing confusion.)  Adapt to use the new name,
but also fall back to checking for the old name.

Cc'ing to stable so that older kernels will remain compatible with
newer Tilera boot infrastructure.

The previous configuration used the wrong "clk" pin.  Without this
change mv_sdio worked because the bootloader would set the pin up, but
with a bootloader that does not set the pin, mv_sdio fails to detect any
card.

I have tested this change using a mwifiex_sdio wireless network adapter
over the SDIO interface.

Sebastian Hesselbarth 0d0644ebc6 ARM: Kirkwood: fix unused mvsdio gpio pins
mvsdio_platform_data allows to pass card detect and write protect gpio
numbers to the driver. Some kirkwood boards don't use both pins as they
are not connected, and don't set the corresponding value in platform_data.

This will leave the unset values in platform_data initialized as 0, which
is in fact a valid gpio pin. mvsdio will grab that pin and configure it as
gpio, which in turn breaks nand controller as mpp0 also carries nand_io2.

This patch fixes the above by initializing unused gpio functions in the
platform_data with an invalid (-1) value.

Gregory CLEMENT 7f23f62fc3 arm: mvebu: Use local interrupt only for the timer 0
The commit 3a6f08a37 "arm: mvebu: Add support for local interrupt",
managed the 28th first interrupts as local interrupt to match the
hardware specification. Among these interrupts there are the Gigabits
Ethernet ones used by the mvneta driver. Unfortunately the state of
the percpu_irq API prevents the driver to use it.

Indeed the interrupts have to be freed when the .stop() function is
called. As the free_percpu_irq() function don't disable the interrupt
line, we have to do it on each CPU before calling this. The function
disable_percpu_irq() only disable the percpu on the current CPU and
there is no function which allows to disable a percpu irq on a given
CPU. Waiting for the extension of the percpu_irq API, this fix allows
to use again the mvneta driver.

Pull Xen bug-fixes from Konrad Rzeszutek Wilk:
 "This is mostly just the last stragglers of the regression bugs that
  this merge window had.  There are also two bug-fixes: one that adds an

  added in v3.7 (the v1 was faulty, the v2 works).

   - Regression fixes for C-and-P states not being parsed properly.
   - Fix possible security issue with guests triggering DoS via
     non-assigned MSI-Xs.
   - Fix regression (introduced in v3.7) with raising an event (v2).
   - Fix hastily introduced band-aid during c0 for the CR3 blowup."

Lee Jones 265c3c0a64 ARM: ux500: Enable the clock controlling Ethernet on Snowball
This fixes a regression introduced by common clk enablement.

On some u8500 based boards, the FMSC clock which is usually used
for flash, is wired up to the SMSC911x Ethernet driver. However,
the SMSC911x doesn't have common clk support yet, rendering it
unusable. Prior to the introduction of common clk the FMSC clock
was default on; however, common clk disables all clocks by default
and insists drivers take responsibility to enable theirs.

This fix enables the FMSC clock on Snowball, subsequently turning
on the SMSC911x Ethernet chip. It will be removed when the driver
is compatible with common clk.

Lee Jones 26135256d3 ARM: ux500: Stop passing ios_handler() as an MMCI power controlling call-back
This fixes a regression introduced during the v3.9 merge window.

Now MMCI on/off functionality is using the regulator framework
from the MMCI driver, if we provide the ios_handler call-back we
essentially duplicate functionality, which causes a large mess
and lots of booting issues.

This fixes a regression introduced by commit:
  05ec260 mfd:db8500-prcmu: update resource passing

All DBx5x0 based SoCs have access to two Tightly Coupled Memory
(TCM) locations based on the PRCMU itself. One area from program
memory (TCPM) and one for data memory (TCDM). The PRCMU needs to
know where these are in order to function correctly. However,
these are currently passed though platform device resources, which
can only be obtained if Device Tree booting isn't in use. Thus we
must also support them in DT by supplying them through the PRCMU
node.

Konrad Rzeszutek Wilk d3eb2c89e7 xen/mmu: Move the setting of pvops.write_cr3 to later phase in bootup.
We move the setting of write_cr3 from the early bootup variant
(see git commit 0cc9129d75
"x86-64, xen, mmu: Provide an early version of write_cr3.")
to a more appropiate location.

This new location sets all of the other non-early variants
of pvops calls - and most importantly is before the
alternative_asm mechanism kicks in.

Rajendra Nayak ff931c821b ARM: OMAP: clocks: Delay clk inits atleast until slab is initialized
clk inits on OMAP happen quite early, even before slab is available.
The dependency comes from the fact that the timer init code starts to
use clocks and hwmod and we need clocks to be initialized by then.

There are various problems doing clk inits this early, one is,
not being able to do dynamic clk registrations and hence the
dependency on clk-private.h. The other is, inability to debug
early kernel crashes without enabling DEBUG_LL and earlyprintk.

Doing early clk init also exposed another instance of a kernel
panic due to a BUG() when CONFIG_DEBUG_SLAB is enabled.

[    0.000000] Kernel panic - not syncing: Attempted to kill the idle task!

It was a know issue, that slab allocations would fail when common
clock core tries to cache parent pointers for mux clocks on OMAP,
and hence a patch 'clk: Allow late cache allocation for clk->parents,
commit 7975059d' was added to work this problem around.
A BUG() within kmalloc() with CONFIG_DEBUG_SLAB enabled was completely
overlooked causing this regression.

More details on the issue reported can be found here,
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg85932.html

With all these issues around clk inits happening way too early, it
makes sense to at least move them to a point where dynamic memory
allocations are possible. So move them to a point just before the
timer code starts using clocks and hwmod.

This should at least pave way for clk inits on OMAP moving to dynamic
clock registrations instead of using the static macros defined in
clk-private.h.

The issue with kernel panic while CONFIG_DEBUG_SLAB is enabled
was reported by Piotr Haber and Tony Lindgren and this patch
fixes the reported issue as well.
