Fix AC97 build breakage with converting to the shared AT91/AVR32 AC97 driver:
struct atmel_ac97_data -> struct ac97c_platform_data
CONFIG_SND_AT91_AC97 -> CONFIG_SND_ATMEL_AC97C

This moves the mmci platform data definition struct away from
arch/arm/include/asm/mach/mmc.h into the more proper place among
the other primecells in include/linux/amba/mmci.h and at the same
time renames it to "mmci.h", and also the struct in this file
confusingly named mmc_platform_data has been renamed
mmci_platform_data for clarity.

This removes the totally bogus bus ID:s with two-digit hex numerals
either referring to the base address of corresponding versatile
machine or just some arbitrarily chosen digit in favor of just using
the device identifier as a string. I kept the "dev:" prefix for
DevChips, "fpga:" prefix for FPGA:s and "issp:" prefix for the
other processor bus, just in case someone likes them.

ARM kprobes use an illegal instruction to trigger kprobes. In the
current implementation, there's a race between the unregistration of a
kprobe and the illegal instruction exception handler if they run at the
same time on different cores.
When reading the value of the undefined instruction, the exception
handler might get the original legal instruction as just patched
concurrently by arch_disarm_kprobe(). When this happen the kprobe
handler won't run, and thus the exception handler will oops because it
believe it just hit an undefined instruction in kernel space.
The following patch synchronizes the code patching in the kprobes
unregistration using stop_machine and thus avoids the above race.

ARMv6 introduces non-executable mappings, which can cause prefetch aborts
when an attempt is made to execute from such a mapping. Currently, this
causes us to loop in the page fault handler since we don't correctly
check for proper permissions.
Fix this by checking that VMAs have VM_EXEC set for prefetch aborts.

Since we get notified separately about prefetch aborts, which may be
permission faults, we need to check for appropriate access permissions
when handling a fault. This patch prepares us for doing this by
separating out the access error checking.

The patch adds a CLREX or dummy STREX to the exception return path. This
is needed because several atomic/locking operations use a pair of
LDREX/STREXEQ and the EQ condition may not always be satisfied. This
would leave the exclusive monitor status set and may cause problems with
atomic/locking operations in the interrupted code.
With this patch, the atomic_set() operation can be a simple STR
instruction (on SMP systems, the global exclusive monitor is cleared by
STR anyway). Clearing the exclusive monitor during context switch is no
longer needed as this is handled by the exception return path anyway.

The definition of the SPI clock phase for the Motorola mode of
the PL022 driver was incorrect: the spec had been interpreted as
data being recieved on rising or falling edge of the clocks while
the correct interpretation is that data can be recieved on the
first or second edge transition, falling or rising depending on
the polarity setting.

This adds the long debated sched_clock() override for the weak
in-kernel jiffybased sched_clock(). The implementation is more or
less identical to the one used in arch/arm/plat-omap/common.c
and at last attempt to merge this the merge was postponed at the
request of Peter Zijlstra due to pending discussions regarding
generalized clocksource-based sched_clock() implementations by
adding a flag to the clocksource. However that discussion ended
up with the generic code needing to be rewritten and Paul Mundt
see no reason not to proceed with this for the time being as it
can be easily converted once the generic code is in place.

Optimized version of copy_page() was written with assumption that cache
line size is 32 bytes. On Cortex-A8 cache line size is 64 bytes.
This patch tries to generalize copy_page() to work with any cache line
size if cache line size is multiple of 16 and page size is multiple of
two cache line size.
After this optimization we've got ~25% speedup on OMAP3(tested in
userspace).
There is test for kernelspace which trigger copy-on-write after fork():
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#define BUF_SIZE (10000*4096)
#define NFORK 200
int main(int argc, char **argv)
{
char *buf = malloc(BUF_SIZE);
int i;
memset(buf, 0, BUF_SIZE);
for(i = 0; i < NFORK; i++) {
if (fork()) {
wait(NULL);
} else {
int j;
for(j = 0; j < BUF_SIZE; j+= 4096)
buf[j] = (j & 0xFF) + 1;
break;
}
}
free(buf);
return 0;
}
Before optimization this test takes ~66 seconds, after optimization
takes ~56 seconds.
