Will Deacon 24b44a66fa ARM: 5889/1: Add atomic64 routines for ARMv6k and above.
In preparation for perf-events support, ARM needs to support atomic64_t
operations. v6k and above support the ldrexd and strexd instructions to
do just that.

This patch adds atomic64 support to the ARM architecture. v6k and above
make use of new instructions whilst older cores fall back on the generic
solution using spinlocks. If and when v7-M cores are supported by Linux,
they will need to fall back on the spinlock implementation too.

This patch implements support for ARMv6 performance counters in the
Linux performance events subsystem. ARMv6 architectures that have the
performance counters should enable HW_PERF_EVENTS to get hardware
performance events support in addition to the software events.

Note: only ARM Ltd ARM cores are supported.

This implementation also provides an ARM PMU abstraction layer to allow
ARMv7 and others to be supported in the future by adding new a
'struct arm_pmu'.

This includes initial support for the SH7367 (SH-Mobile G3) CPU and

Russell King 1937f5b918 ARM: fix sa1100 build
Fix:

arch/arm/mach-sa1100/generic.c:117: error: redefinition of 'cpufreq_get'
include/linux/cpufreq.h:299: error: previous definition of 'cpufreq_get' was here

cpufreq_get() is used on these platforms to tell drivers what the CPU
frequency is, and therefore the bus frequency - which is critical for
setting the PCMCIA and LCD timings.  Adding ifdefs to these drivers to
select cpufreq_get() or some other interface adds confusion.  Making
these drivers use some other interface for the normal paths and cpufreq
stuff for the cpufreq notifier is insane as well.

(Why x86 can't provide a version of cpufreq_get() which returns the
CPU frequency when CPUFREQ is disabled is beyond me, rather than
requiring a dummy zero-returning cpufreq_get().  Especially as they
do:

			unsigned long khz = cpufreq_get(cpu);
			if (!khz)
				khz = tsc_khz;

In other words, if CPUFREQ is disabled, get it from tsc_khz - why
not provide a dummy cpufreq_get() which returns tsc_khz?)

We inted to re-organise the plat-s3c/plat-s3c24xx/plat-s3c64xx into a

to make it easier to port new devices and try and clear up some of the
