Patch from Andrew Victor
This patch adds the core Power Management support for the AT91RM9200
processor. It will support suspend-to-RAM and standby modes.
The suspend-to-RAM functionality is not 100% complete. The code that
needs to be execute from the internal SRAM to restore the system is
outstanding. For now we just fall through to Standby mode.
The AT91-specific at91_suspend_entering_slow_clock() function will
eventually be replaced by clk_must_disable() once that functionality is
added to mainline clock API.

This adds the platform device for SSP/SPI controller, and declares

to populate the connector needed to use this instead of the ucb1400
chip, but it can always be used as a temperature sensor.
In short, this is probably most useful as an example of how to
provide the configuration data used by the pxa2xx_spi driver.

There's not much point in splitting the sigmask between two different

These two members appear to be surplus to requirements. Discussing
this issue with glibc folk:

| We can kill them. I checked with Phil B. about them last week, and he
| didn't remember any reason they still needed to be there. And nothing
| should know where they are on the stack. Unfortunately, doing this
| will upset GDB, which knows that the saved registers are 0x88 bytes
| above the stack pointer on entrance to an rt signal trampoline; but,
| since puc and pinfo are quite recognizable, I can adapt GDB to support
| the new layout if you want to remove them.
So remove them.

Patch from Paul Brook
The old-abi sys_syscall syscall is broken when called from Thumb mode. It
assumes the syscall number is an Arm syscall number (ie. starts from
__NR_OABI_SYSCALL_BASE). In thumb mode syscall numbers start from zero.
The patch below fixes this by clearing the nigh bits of the syscall number
instead of inverting them. Technically this means we accept some invalid
syscall numbers, but I can't see how that could be a problem. The two sets of
numbers far apart that unimplemented syscalls should still be rejected.
