Patch from Daniel Jacobowitz
In order for userspace to find saved coprocessor registers, move them from
struct rt_sigframe into struct ucontext. Also allow space for glibc's
sigset_t, so that userspace and kernelspace can use the same ucontext
layout. Define the magic numbers for iWMMXt in the header file for easier
reference. Include the size of the coprocessor data in the magic numbers.
Also define magic numbers and layout for VFP, not yet saved.

VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense
to do this to vga_vram_base, because we're going to access memory between
vga_vram_base and vga_vram_end.
But it doesn't really make sense to map starting at vga_vram_end, because
we aren't going to access memory starting there. On ia64, which always has
to be different, ioremapping vga_vram_end gives you something completely
incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being
nonsense.
As a bonus, we often know the size up front, so we can use ioremap()
correctly, rather than giving it a zero size.

Some machine classes need to allow VFP support to be built into the
kernel, but still allow the kernel to run even though VFP isn't
present. Unfortunately, the kernel hard-codes VFP instructions
into the thread switch, which prevents this being run-time selectable.
Solve this by introducing a notifier which things such as VFP can
hook into to be informed of events which affect the VFP subsystem
(eg, creation and destruction of threads, switches between threads.)

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.

Patch from Lennert Buytenhek
The current __ixp23xx_arch_is_coherent() check assumes that the
lower byte of IXP23XX_PRODUCT_ID is identical to the lower byte of
processor_id, but this is not the case, and because of this we were
incorrectly enabling coherency on A1 stepping CPUs.
Stepping A1 of the ixp2350, which has a PRODUCT_ID of 0x401, has '02'
in the lower byte of processor_id, while A2, with a PRODUCT_ID of
0x402, has '04' in the lower byte of processor_id.
So, to check for >= A2, we really need to check the lower byte of
processor_id against >= 4.
