Revert commit ff4da2e262.
It broke APM suspend, probably because APM doesn't switch back to a VT
when suspending.
Tracked down by Matt Mackall <mpm@selenic.com>
Rafael sayeth:
"It only fixed the theoretical issue that a quick-handed user could
switch to X after processes have been frozen and before the devices
are suspended.
With the current userland suspend tools it shouldn't be necessary."

ia32_setup_arg_pages would ignore the passed in random stack top
and use its own static value.
Now it uses the 8bit of randomness native i386 would use too.
This indirectly fixes mmap randomization for 32bit processes too,
which depends on the stack randomization.
Should also give slightly better virtual cache colouring and
possibly better performance with HyperThreading.

Some driver wants to use CMSPAR, but it was missing on alpha and powerpc.
This adds it, with the same value as every other architecture uses.

Using asm-generic/dma-mapping.h does not work because pushing
the call down to pci_alloc_coherent() causes the gfp_t argument
of dma_alloc_coherent() to be ignored.
Fix this by implementing things directly, and adding a gfp_t
argument we can use in the internal call down to the PCI DMA
implementation of pci_alloc_coherent().
This fixes massive memory corruption when using the sound driver
layer, which passes things like __GFP_COMP down into these
routines and (correctly) expects that to work.

This patch enables agpgart on a Via "PT880 Ultra" based motherboard
(Asus P4V800D-X). The PCI ID of the PT880 Ultra is 0x0308 instead of
0x0258 of the PT880.
The patched via-agp passes testgart.

Andy added code to buddy allocator which does not require the zone's
endpoints to be aligned to MAX_ORDER. An issue is that the buddy allocator
requires the node_mem_map's endpoints to be MAX_ORDER aligned. Otherwise
__page_find_buddy could compute a buddy not in node_mem_map for partial
MAX_ORDER regions at zone's endpoints. page_is_buddy will detect that
these pages at endpoints are not PG_buddy (they were zeroed out by bootmem
allocator and not part of zone). Of course the negative here is we could
waste a little memory but the positive is eliminating all the old checks
for zone boundary conditions.
SPARSEMEM won't encounter this issue because of MAX_ORDER size constraint
when SPARSEMEM is configured. ia64 VIRTUAL_MEM_MAP doesn't need the logic
either because the holes and endpoints are handled differently. This
leaves checking alloc_remap and other arches which privately allocate for
node_mem_map.

Fix some outstanding issues with the pxa2xx_spi driver when running on a
PXA270:
- Wrong timeout calculation in the setup function due to different
peripheral clock rates in the PXAxxx family.
- Bad handling of SSSR_TFS interrupts in interrupt_transfer function.
- Added locking to interface between the pump_messages workqueue and the
pump_transfers tasklet.
Much thanks to Juergen Beisert for the extensive testing on the PXA270.
