David VomLehn 0d365753d0 MIPS: PowerTV: Separate PowerTV USB support from non-USB code
Separate USB code into a file separate from asic/asic_devices.

Separating the USB code from everything else in asic/asic_devices.c goes
a long way toward reducing the use of that file as a dumping ground for
everything that didn't seem to fit anywhere else.

David Daney 2b5987abaf MIPS: Octeon: Allow more than 3.75GB of memory with PCIe
We reserve the 3.75GB - 4GB region of PCIe address space for device to
device transfers, making the corresponding physical memory under
direct mapping unavailable for DMA.

To allow for PCIe DMA to all physical memory we map this chunk of
physical memory with BAR1.  Because of the resulting discontinuity in
the mapping function, we remove a page of memory at each end of the
range so multi-page DMA buffers can never be allocated that span the
range.

David Daney 70dc6f045f MIPS: Clean up notify_die() usage.
The sixth argument of notify_die() is a signal number, the fifth is a
trap number.

Instead of passing a signal number in a randomly selected argument,
pass it in the sixth.  Extract the exception code from regs and pass
that as the trap number.

Get rid of redundant cast, and remove some gratuitous spaces.

Nobody actually does anything with the signal number or trap number,
but we might as well populate them with sensible values.

This patch is based on previous work by Sony and Himanshu Chauhan.

I have done some cleanup and implemented JProbes and KRETPROBES.  The
KRETPROBES part is pretty much copied verbatim from powerpc.  A possible
future enhance might be to factor out the common code.

David Daney 7d9eee6e52 MIPS: Octeon: Make MSI use handle_simple_irq().
The use of handle_percpu_irq() is not really what we want for MSI, use
handle_simple_irq() instead.  This is probably the prototypical case
for using handle_simple_irq(), because all the MSIs are dispatched from
the root interrupt service routine.

Also since the base IRQ is not shared, don't pass IRQF_SHARED.

David Daney 5aae1fd4d4 MIPS: Octeon: Improve interrupt handling.
The main change is to change most of the IRQs from handle_percpu_irq
to handle_fasteoi_irq.  This necessitates extracting all the .ack code
to common functions that are not exposed to the irq core.

The affinity code now acts more sanely, by doing round-robin
distribution instead of broadcasting.

Because of the change to handle_fasteoi_irq and affinity, some of the
IRQs had to be split into separate groups with their own struct
irq_chip to prevent undefined operations on specific IRQ lines.

Additional changes to Youichi Yuasa's command line simplication code

The PowerTV platform uses a non-standard way to get the kernel command
line--we insert a built-in command line into arcs_cmdline and to
get additional command line information from the bootloader via a
pointer in the a1 register. It is necessary to insert a space between
to the two strings or the last argument from arcs_cmdline and the first
argument from the bootloader may be inadvertantly combined.

It is also necessary to set CONFIG_CMDLINE_BOOL to "y" and to set the
default command line to an empty string to get the simplified code to
work properly in the PowerTV environment.

Sam Ravnborg 35eaa1e9c9 MIPS: Refactor arch/mips/boot/compressed/Makefile
- use hostprogs-y for the elf2ecoff
- list all *.o file in targets
- renamed obj-y to vmlinuzobjs-y (it was confusing to re-use a kbuild variable)
- fix all uses of if_changed/cmd
- use kbuild rules to beautify output
- update clean-file to clean vmlinuz.* in top-level directory

- simplied logic in arch/mips/Makefile for compressed targets

The net result is a more kbuild conformant Makefile but
readability did not increase.

Sam Ravnborg 5d25b01cf9 MIPS: Introduce support for Platform definitions
Move platform specific definitions to the platfrom directories.

Each platform shall do the following:
1) include an entry in arch/mips/Kbuild.platforms
2) add relevant definitions to arch/mips/<platform>/Platform

This commits changes ar7 to the new scheme as an example.

Introducing a platform speecific Platfrom file has following advantages:
1) decentralization of platfrom definitions
2) simplification af arch/mips/Makefile
3) force all platfrom to build with -Werror (done in arch/mips/Kbuild)

Sam Ravnborg 66f9ba101f MIPS: Add -Werror to arch/mips/Kbuild
Adding subdirs-ccflags-y := -Werror to arch/mips/Kbuild
let us in one go cover all files with -Werror.

In addition this allows us to remove the
individual -Werror definition in various Makefile.

Adding the definition to Kbuild as a recursive
option help us not to forget to do so.

With this change we now compile arch/mips/kernel/cpufreq with -Werror

One drawback:
When specifying a subdirectory covered by the Kbuild file like this:

    make arch/mips/kernel/

then kbuild fails to pick up the -Werror definition.

David VomLehn ca36c36b78 MIPS: PowerTV: Use O(1) algorthm for phys_to_dma/dma_to_phys
Replace phys_to_dma()/dma_to_phys() looping algorithm with an O(1) algorithm
The approach taken is inspired by the sparse memory implementation: take a
certain number of high-order bits off the address them, use this as an
index into a table containing an offset to the desired address and add
it to the original value. There is a table for mapping physical addresses
to DMA addresses and another one for the reverse mapping. The table sizes
depend on how fine-grained the mappings need to be; Coarser granularity
less to smaller tables.  On a processor with 32-bit physical and DMA
addresses, with 4 MIB granularity, memory usage is two 2048-byte arrays.
Each 32-byte cache line thus covers 64 MiB of address space.

Also, renames phys_to_bus() to phys_to_dma() and bus_to_phys() to
dma_to_phys() to align with kernel usage.

huge array on stack.]

Hauke Mehrtens aec9222551 MIPS: BCM47xx: Really fix 128MB RAM problem
The previous patch 4a86f2d27733f610e642649aca3e82e86fca9e22 (lmo) rsp.
84a6fcb368 (kernel.org) was wrong.

The BCM47xx architecture maps the ram into a 128MB address space. It
will be spaced there as often as goes into the 128MB. Detection tries to
find the position where the same memory is found. When reading beyond
128MB the processor will throw an exception. If 128MB RAM is installed,
it will not find a memory alias because it tries to read beyond the 128MB
border. Now it just assumes 128MB installed ram if it can not find an
alias.

Sam Ravnborg 6588169d51 kbuild: allow assignment to {A,C,LD}FLAGS_MODULE on the command line
It is now possible to assign options to AS, CC and LD
on the command line - which is only used when building modules.

{A,C,LD}FLAGS_MODULE was all used both in the top-level Makefile
in the arch makefiles, thus users had no way to specify
additional options to AS, CC, LD when building modules
without overriding the original value.

Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE
that is used by arch specific files and free up
{A,C,LD}FLAGS_MODULE so they can be assigned on
the command line.

All arch Makefiles that used the old variables has been updated.

Note: Previously we had a MODFLAGS variable for both
AS and CC. But in favour of consistency this was dropped.
So in some cases arch Makefile has one assignmnet replaced by
two assignmnets.

Note2: MODFLAGS was not documented and is dropped
without any notice. I do not expect much/any breakage
from this.

Bruno Randolf 98a0f86a54 MIPS: MTX-1: Fix PCI on the MeshCube and related boards
This patch fixes a regression introduced by commit "MIPS: Alchemy: MTX-1:
Use linux gpio api." (bb706b28bb) which broke
PCI bus operation. The problem is caused by alchemy_gpio2_enable() which
resets the GPIO2 block. Two PCI signals (PCI_SERR and PCI_RST) are connected
to GPIO2 and they obviously do not to like the reset. Since GPIO2 is
correctly initialized by the boot monitor (YAMON) it is not necessary to
call this function, so just remove it.

Also replace gpio_set_value() with alchemy_gpio_set_value() to avoid
problems in case gpiolib gets initialized after PCI. And since alchemy
gpio_set_value() calls au_sync() we don't have to au_sync() again later.

Quoting from Jiri Slaby's patch of a similar nature for x86:

    When initrd is in use and a driver does request_module() in its
    module_init (i.e. __initcall or device_initcall), a modprobe
    process is created with VDSO mapping. But VDSO is inited even in
    __initcall, i.e. on the same level (at the same time), so it may
    not be inited yet (link order matters).

Move init_vdso up to subsys_initcall to avoid the issue.

Waldemar Brodkorb 121915c4ee MIPS: BCM47xx: Add NVRAM support devices
When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails,
because of following error message:

...
[    0.424000] b44: b44.c:v2.0
[    0.424000] b44: Invalid MAC address found in EEPROM

[    0.436000] b44: probe of ssb0:1 failed with error -22
...

The router uses a CFE bootloader, but most of the needed environment
variables for network card initialization, are not available from CFE
via printenv and even though not via cfe_getenv().
The required environment variables are saved in a special partition
in flash memory. The attached patch implement nvram_getenv and enables
bootup via NFS root on my router.

Most of the patch is extracted from the OpenWrt subversion repository and
stripped down and cleaned up to just fix this issue.

David Daney 0453fb3c52 MIPS: Use GCC __builtin_prefetch() to implement prefetch().
GCC's __builtin_prefetch() was introduced a long time ago, all
supported GCC versions have it.  Lets do what the big boys up in
linux/prefetch.h do, except we use '1' as the third parameter to
provoke 'PREF 0,...'  and 'PREF 1,...' instead of other prefetch
hints.

This allows for better code generation.  In theory the existing
embedded asm could be optimized, but the compiler has these builtins,
so there is really no point.

Florian Fainelli 142a2ceea7 MIPS: AR7: prevent race between clock initialization and devices registration
ar7_regiser_devices needs ar7_clocks_init to have been called first,
however clock.o is currently linked later due to its order in the Makefile,
therefore ar7_clocks_init always gets called later than ar7_register_devices
because both have the same initcall level. Fix this by moving
ar7_register_devices to the right initcall level.

Kevin Cernekee 0103d23f44 MIPS: nofpu and nodsp only affect CPU0
The "nofpu" and "nodsp" kernel command line options currently do not
affect CPUs that are brought online later in the boot process or
hotplugged at runtime.  It is desirable to apply the nofpu/nodsp options
to all CPUs in the system, so that surprising results are not seen when
a process migrates from one CPU to another.

[Ralf: Moved definitions of mips_fpu_disabled, fpu_disable,
mips_dsp_disabled and dsp_disable from setup.c to cpu-probe.c to allow
making mips_fpu_disabled and mips_dsp_disabled static.]

Jason Wessel 5dd11d5d47 mips,kgdb: kdb low level trap catch and stack trace
The only way the debugger can handle a trap in inside rcu_lock,
notify_die, or atomic_notifier_call_chain without a recursive fault is
to have a low level "first opportunity handler" do_trap_or_bp() handler.

Generally this will be something the vast majority of folks will not
need, but for those who need it, it is added as a kernel .config
option called KGDB_LOW_LEVEL_TRAP.

Also added was a die notification for oops such that kdb can catch an
oops for analysis.

There appeared to be no obvious way to pass the struct pt_regs from
the original exception back to the stack back tracer, so a special
case was added to show_stack() for when kdb is active because you
generally desire to generally look at the back trace of the original
exception.

Jason Wessel dcc7871128 kgdb: core changes to support kdb
These are the minimum changes to the kgdb core in order to enable an
API to connect a new front end (kdb) to the debug core.

This patch introduces the dbg_kdb_mode variable controls where the
user level I/O is routed.  It will be routed to the gdbstub (kgdb) or
to the kdb front end which is a simple shell available over the kgdboc
connection.

You can switch back and forth between kdb or the gdb stub mode of
operation dynamically.  From gdb stub mode you can blindly type
"$3#33", or from the kdb mode you can enter "kgdb" to switch to the
gdb stub.

The logic in the debug core depends on kdb to look for the typical gdb
connection sequences and return immediately with KGDB_PASS_EVENT if a
gdb serial command sequence is detected.  That should allow a
reasonably seamless transition between kdb -> gdb without leaving the
kernel exception state.  The two gdb serial queries that kdb is
responsible for detecting are the "?" and "qSupported" packets.

Shane McDonald 95e8f634d7 MIPS FPU emulator: allow Cause bits of FCSR to be writeable by ctc1
In the FPU emulator code of the MIPS, the Cause bits of the FCSR register
    are not currently writeable by the ctc1 instruction.  In odd corner cases,
    this can cause problems.  For example, a case existed where a divide-by-zero
    exception was generated by the FPU, and the signal handler attempted to
    restore the FPU registers to their state before the exception occurred.  In
    this particular setup, writing the old value to the FCSR register would
    cause another divide-by-zero exception to occur immediately.  The solution
    is to change the ctc1 instruction emulator code to allow the Cause bits of
    the FCSR register to be writeable.  This is the behaviour of the hardware
    that the code is emulating.
    
    This problem was found by Shane McDonald, but the credit for the fix goes
    to Kevin Kissell.  In Kevin's words:
    
    I submit that the bug is indeed in that ctc_op:  case of the emulator.  The
    Cause bits (17:12) are supposed to be writable by that instruction, but the
    CTC1 emulation won't let them be updated by the instruction.  I think that
    actually if you just completely removed lines 387-388 [...] things would
    work a good deal better.  At least, it would be a more accurate emulation of
    the architecturally defined FPU.  If I wanted to be really, really pedantic
    (which I sometimes do), I'd also protect the reserved bits that aren't
    necessarily writable.

Wu Zhangjin 64fc74f5f6 MIPS: Loongson 2F: Fix of problems introduced by -mfix-loongson2f-jump
The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed
the out-of-order issue of Loongson-2F described in chapter 15 of the
Loongson2F User Manual [1, 2], but introduced some problems.

The option changes all of the jump target to "addr & 0xcfffffff" through the
at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is
wrong.  Avoids the problem via telling the assembler to not use the $at
register.

Wu Zhangjin 622844bf0b MIPS: Loongson: Add CPU_LOONGSON2F_WORKAROUNDS
As documented in the  Loongson 2F User Manual [2, 3], the old Loongson2F
series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds
in the kernel and binutils.  This issue has been rectified in Loongson 2F
series 2F03 so no workarounds needed.

Now that the workarounds [1] adding the the -mfix-loongson2f-nop and
-mfix-loongson2f-jump options have been comitted to the binutils the CVS
repository), we can add the workarounds in the kernel.

The workarounds have no significant side effect on the system but may
decrease performance so we control them through a a new
CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable
it as necessary.

Before this we were using XKPHYS/cached as ebase and computed the uncached

CKSEG1 for this. CKSEG1ADDR does just that in 32-bit and 64-bit.

David Daney 1ec56329ff MIPS: Check for accesses beyond the end of the PGD.
For some combinations of PAGE_SIZE and vmbits, it is possible to have
userspace access that are beyond what is covered by the PGD, but within
vmbits.  Such an access would cause the TLB refill handler to load garbage
values for PMD and PTE potentially giving userspace access to parts of the
physical address space to which it is not entitled.

In the TLB refill hot path, we add a single dsrl instruction so we can
check if any bits outside of the range covered by the PGD are set.  In
the vmalloc side we then separate the bad case from the normal vmalloc
case and call tlb_do_page_fault_0 if warranted.  This slows us down a
bit, but has the benefit of yielding deterministic behavior.

Due to how the TLB refill handlers work, any mapping established in
xkseg or ksseg will also establish a xuseg mapping that should never
be used by the kernel.

In order to be able to use exceptions to trap NULL pointer
dereferences, we need to ensure that nothing is mapped at address
zero.  Since vmap mappings in xkseg are reflected in xuseg, this means
we need to ensure that there are no vmap mappings established at the
start of xkseg.  So we move back VMALLOC_START to avoid establishing
vmap mappings at the start of xkseg.

commit 5a0e3ad6af
    Author: Tejun Heo <tj@kernel.org>
    Date:   Wed Mar 24 17:04:11 2010 +0900

        include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

Since a while the few headers included don't drag in <linux/kernel.h>
anymore, thus no more prototype of printk() resulting in:

David Daney f6be75d03c MIPS: Calculate proper ebase value for 64-bit kernels
The ebase is relative to CKSEG0 not CAC_BASE.  On a 32-bit kernel they
are the same thing, for a 64-bit kernel they are not.

It happens to kind of work on a 64-bit kernel as they both reference
the same physical memory.  However since the CPU uses the CKSEG0 base,
determining if a J instruction will reach always gives the wrong result
unless we use the same number the CPU uses.

Manuel Lauss d8000beef2 MIPS: Alchemy: DB1200: Remove custom wait implementation
While playing with the out-of-tree MAE driver module, the system would
panic after a while in the db1200 custom wait code after wakeup due to
a clobbered k0 register being used as target address of a store op.

Remove the custom wait implementation and revert back to the Alchemy-
recommended implementation already set as default.

Anton Altaparmakov 7b3e543ddb MIPS: Fix __vmalloc() etc. on MIPS for non-GPL modules
Commit b3594a089f1c17ff919f8f78505c3f20e1f6f8ce (lmo) rsp.
351336929c (kernel.org) break non-GPL modules
that use __vmalloc() or any of the vmap(), vm_map_ram(), etc functions on
MIPS.

All those functions are EXPORT_SYMBOL() so are meant to be allowed to be
used by non-GPL kernel modules.  These calls all take page protection as
an argument which is normally a constant like PAGE_KERNEL.

This commit causes all protection constants like PAGE_KERNEL to not be
constants and instead to contain the GPL-only symbol _page_cachable_default.

This means that all calls to __vmalloc(), vmap(), etc, cause non-GPL
modules to fail to link with the complaint that they are trying to use the
GPL-only symbol _page_cachable_default...

Change EXPORT_SYMBOL_GPL(_page_cachable_default) to EXPORT_SYMBOL() for
non-GPL modules that call __vmalloc(), vmap(), vm_map_ram() etc.
