The s3c24xx_va_gpio2 variable is only used
when the S3C2412 and another cpu-type is
being used in the kernel. This patch ensures
it is not set when it is not being used.Fixes bug report by Thomas Gleixner.

Signed-off-by: Russell King -
On stepping A0/A1 of the 80200, invalidating D-cache by line doesn't
clear the dirty bits, which means that if we invalidate a dirty line,
the dirty data can still be written back to memory later on.To work around this, dma_inv_range() on these two processors is
implemented as dma_flush_range() (i.e. do a clean D-cache line before
doing the invalidate D-cache line.) For this, we currently have a
processor ID check in xscale_dma_inv_range(), but a better solution
is to add a separate cache_fns and proc_info for A0/A1 80200.Signed-off-by: Lennert Buytenhek

Prevent userland from mapping in physical address regions >= 4G by
checking for that in valid_mmap_phys_addr_range().Unfortunately, we cannot override valid_mmap_phys_addr_range() without
also overriding valid_phys_addr_range(), so copy drivers/char/mem.c's
version of valid_phys_addr_range() over to arch/arm/mm/mmap.c as well.Signed-off-by: Lennert Buytenhek

Now that we have raw_* variants of local_irq_$FOO(), switch the atomic
helpers over to use those raw_* variants. This is necessary when using
lockdep on pre-ARMv6 hardware, as lockdep uses atomic_t counters in the
trace_hardirqs_off() path.Signed-off-by: Lennert Buytenhek

Change to using flush_cache_all() in pm.c and
also remove the need to flush the cache in the
PM code.This changes the sleep.S code to have an entry
to store the registers for resume, and then a
second entry (after the caches are cleaned)
to do the suspend and resume.Signed-off-by: Ben Dooks

Seperate the IRQ power management code out of
the pm.c file, and add it to the relevant
system class devices.Also make the suspend and resume code take
notice of the fact these registers can be
moved by compile time code.Add fix from Ilya Yanok to also save the
INTSUBMSK over sleep.Signed-off-by: Ben Dooks

Patch from Daniel Jacobowitz
The ARM kernel has several uses of asm("foo%?"). %? is a GCC internal
modifier used to output conditional execution predicates. However, no
version of GCC supports conditionalizing asm statements. GCC 4.2 will
correctly expand %? to the empty string in user asms. Earlier versions may
reuse the condition from the previous instruction. In 'if (foo) asm
("bar%?");' this is somewhat likely to be right... but not reliable.So, the only safe thing to do is to remove the uses of %?. I believe
the tlbflush.h occurances were supposed to be removed before, based
on the comment about %? not working at the top of that file.Old versions of GCC could omit branches around user asms if the asm didn't
mark the condition codes as clobbered. This problem hasn't been seen on any
recent (3.x or 4.x) GCC, but it could theoretically happen. So, where
%? was removed a cc clobber was added.Signed-off-by: Daniel Jacobowitz

The common case for the thread notifier is a context switch. Tell
gcc that this is the most likely condition so it can optimise the
function for this case.Signed-off-by: Russell King

ARM has interrupts enabled over context switches (iow, has
__ARCH_WANT_INTERRUPTS_ON_CTXSW defined.) The lockdep code in fork.c
assumes that interrupts are always disabled. Fix this wrong
assumption by making the initialisation of 'p->hardirqs_enabled'
depend on __ARCH_WANT_INTERRUPTS_ON_CTXSW.Acked-by: Ingo Molnar

This reverts commits 11012d419cfc0e0f78ca356aca03674217910124 and
40dd2d20f220eda1cd0da8ea3f0f9db8971ba237, which allowed us to use the
MMIO accesses for PCI config cycles even without the area being marked
reserved in the e820 memory tables.Those changes were needed for EFI-environment Intel macs, but broke some
newer Intel 965 boards, so for now it's better to revert to our old
2.6.17 behaviour and at least avoid introducing any new breakage.Andi Kleen has a set of patches that work with both EFI and the broken
Intel 965 boards, which will be applied once they get wider testing.Cc: Arjan van de Ven
