Suspend/resume on powermacs uses the pmac_get_boot_time function,
so it can't be marked as __init.

As pointed out by Gary Byers, we were clearing the image of the FPSCR
(floating point status and control register) in the thread_struct before
copying it to the user stack when invoking a signal. Thus the task
would see its FPSCR getting cleared when it took a signal.
While fixing it I noticed that our swapcontext system call was also
clearing FPSCR. It shouldn't, so I fixed that too.

This moves the rtas RTC callbacks to rtas-rtc.c in arch/powerpc/kernel,
and kills the rest of arch/ppc64/kernel/rtc.c which was just a duplicate
of the genrtc functionality. Also enable build of genrtc for
CONFIG_PPC64 (it just works are we already have the required callbacks)
and enable it in all defconfigs.

This fixes various errors in the new functions added in the vDSO's,
I've now verified all functions on both 32 and 64 bits vDSOs. It also
fix a sign extension bug getting the initial time of day at boot that
could cause the monotonic clock value to be completely on bogus for
64 bits applications (with either the vDSO or the syscall) on
powermacs.

This patch uses a FORCE dependency on the arch/powerpc/include/asm

We currently have a ppc_md member called cpu_irq_down, which disables IRQs
for the cpu in question. The only caller of cpu_irq_down is the kexec code.
On pSeries we need to do more than just teardown IRQs at kexec time, so rename
the ppc_md member to kexec_cpu_down and expand it. The pSeries code needs to
know, and other platforms might too, whether we're doing a crash shutdown (ie.
panicking) or a regular kexec, so add a flag for that.
The pSeries implementation of kexec_cpu_down does an unregister VPA call, which
tells the Hypervisor to stop writing stuff into our pacas. Without this we can
get weird memory corruption bugs when we kexec, caused by the Hypervisor
writing into the first kernel's pacas which happens to be somewhere interesting
in the second kernel's memory.

Patch from Richard Purdie
Add a driver for the extra GPIOs found on the Sharp SL-C1000 (Akita).
These GPIOs are found on a Maxim MAX7310 I2C i/o expander chip. A
generic GPIO driver for the MAX7310 was attempted but this mini
driver is a much simpler and much more effective solution avoiding
several issues and complexity the generic driver had (as discussed
on LKML).
The platform device is required so the device parent can be set
correctly which ensures the device is one of the last to suspend
and first to resume. Whilst the i2c suspend/resume calls can be
influenced, nothing guarantees this is easlier/later than the
subsystems the gpios are used on which are all independent of i2c
(sound, irda, video/backlight etc.).
