In mm/slab.c the function do_ccupdate_local requires that interrupts be

So we disable interrupts while processing IPIs.  Also these are not shared

The current code does not request the GPIO and attempts
to set its direction, which is a violation of the GPIO API.
This patch also unhardcode the GPIO we request and use
the one we defined in the button driver.

0ca71737fe MIPS: Simplify and correct interrupt handling for MSP4200
The current interrupt handling code for the MSP4200 always masks an
interrupt before acknowledging it.  This is not required, as that will be
handled by the level interrupt handler.  This change simplifies the MSP4200
code to remove the masking in the ack routine, and makes sure that the
minimum required operation is performed for masking and acking, rather
than always both masking and acking the interrupt.

0e66fff883 MIPS: Fix loading of modules with unresolved weak symbols
Loading of modules with unresolved weak symbols fails on MIPS
since '88173507e4fc1e7ecd111b0565e8cba0cb7dae6d'.

Modules: handle symbols that have a zero value

The module subsystem cannot handle symbols that are zero.  If symbols
are present that have a zero value then the module resolver prints out a
message that these symbols are unresolved.

We have to use IS_ERR_VALUE() to check that a symbol has been resolved
or not.

484889fc85 MIPS: Avoid clobbering struct pt_regs in kthreads
The resume() implementation octeon_switch.S examines the saved cp0_status
register.  We were clobbering the entire pt_regs structure in kernel
threads leading to random crashes.

When switching away from a kernel thread, the saved cp0_status is examined
and if bit 30 is set it is cleared and the CP2 state saved into the pt_regs
structure.  Since the kernel thread stack overlaid the pt_regs structure
this resulted in a corrupt stack.  When the kthread with the corrupt stack
was resumed, it could crash if it used any of the data in the stack that was
clobbered.

We fix it by moving the kernel thread stack down so it doesn't overlay
pt_regs.

9e1b32caa5 mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()

Upcoming paches to support the new 64-bit "BookE" powerpc architecture
will need to have the virtual address corresponding to PTE page when
freeing it, due to the way the HW table walker works.

Basically, the TLB can be loaded with "large" pages that cover the whole
virtual space (well, sort-of, half of it actually) represented by a PTE
page, and which contain an "indirect" bit indicating that this TLB entry
RPN points to an array of PTEs from which the TLB can then create direct
entries. Thus, in order to invalidate those when PTE pages are deleted,
we need the virtual address to pass to tlbilx or tlbivax instructions.

The old trick of sticking it somewhere in the PTE page struct page sucks
too much, the address is almost readily available in all call sites and
almost everybody implemets these as macros, so we may as well add the
argument everywhere. I added it to the pmd and pud variants for consistency.

Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.

The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.

cad9bc6904 MIPS: 64-bit: Fix o32 core dump
If an o32 process generates a core dump on a 64 bit kernel, the core file
will not be correctly recognized. This is because ELF_CORE_COPY_REGS and
ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use
the default register set which would be CONFIG_64BIT in asm/elf.h.

So we'll switch to use the right register defines in this situation by
checking for WANT_COMPAT_REG_H and use the right defines of
ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.

[Ralf: made ELF_CORE_COPY_TASK_REGS() bullet-proof against funny arguments.]

b53d4d1f8d MIPS: Define __arch_swab64 for all mips r2 cpus
Some CPUs implement mipsr2, but because they are a super-set of mips64r2 do
not define CONFIG_CPU_MIPS64_R2.  Cavium OCTEON falls into this category.
We would still like to use the optimized implementation, so since we have
already checked for CONFIG_CPU_MIPSR2, checking for CONFIG_64BIT instead of
CONFIG_CPU_MIPS64_R2 is sufficient.
