profile_pc() used thread_saved_fp() with the current task.  However,
thread_saved_fp() only returns sane values when called for threads
which are presently sleeping, so this caused an oops.  Instead, use
regs->ARM_fp, which correspond with the frame pointer.

Remove asm/smp.h include, use linux/smp.h instead.
Add linux/cpu.h include.

This removes ipi_count from the globally visible per-cpu cpu data
structure.

Provide /proc/irq/*/smp_affinity support, and add necessary methods
to allow a machine to route the interrupt to the desired CPU.

Add the beginnings of SMP support to the ARM architecture, providing
smp.c, smp.h, and cpu.h.  Convert setup.c to use per-cpu for
topology initialisation.

Patch from Lennert Buytenhek

Instead of 'struct sys_timer', the ixdp2400 code has 'struct timer' and the enp2611 has just 'struct', preventing compilation for both machine types.  This patch fixes it up.

Patch from Deepak Saxena

Our case statments are looking at the devfn, but the existing code
does a switch(PCI_SLOT(dev->devfn)). This causes all PCI devices 
behind the first bridge to be configured with IRQ 0. Bad.

Reduce local variable (large struct) stack usage in zoran_do_ioctl() from 1028
bytes to 324 bytes (on x86-32) by declaring & using only 1 "struct
zoran_jpg_settings" instead of 5 instances of it.  Reduced from 5 * 180 bytes
to 1 * 180 bytes, plus other locals in each case.

Attached patch fixes the writing of APP (application-specific) and COM
(comment) markers in the JPEG stream as generated by the zr36050 or zr36060
encoders, both part of the zr36067 driver.

During separating those bits out of the main zoran driver, we accidently
removed the interface through which applications can adapt those markers,
replacing them by unchangeable (static) markers.  Some video formats,
particularly Quicktime and AVI, require specific container-specific markers in
the stream for interlaced streams.  Those markers specify field order and
such.

The attached patch re-adds this feature so that decoders depending on those
container-specific markers for correct playback will work correctly.

Both the r128 and radeon fb drivers do bad things with the PCI BAR
corresponding to their option ROM.  They incorrectly use the host address
instead of the BAR address to enable the ROM, and then incorrectly lose the
original value on unmap.  This patch fixes both problems.  Tested on Altix.

Handle 24bit on big-endian by leaving the hardware in RGB and using the
colour offset to reverse red/blue.  Leaving the hardware in RGB means that
fbi displays images correctly (abeit fortuitously) and the console is
correct, thanks to a recent patch to the console code correcting an endian
bug in fbcon_putc().

A collection of changes that taken together makes the driver work correctly on
big-endian systems, specifically Sparc.

- Remove old PM2FB_BE_APERTURE define and use __BIG_ENDIAN
  throughout. PM2FB_BE_APERTURE wasn't defined on Sparc; this
  was incorrect.
- Replace colour mode magic numbers with suitable constants,
  and tidy colour mode handling. Use BGR not RGB at 24bit on
  big-endian.
- Replace aperture magic numbers with constants. Rearrange code to
  emphasise second aperture is not used. Add short explanations
  of aperture settings for big endian.
- Update comments to note that the driver now works on Sparc.
- Revisit 32bit depth colour offsets and ensure transp is set.

It contains all changes done behind my back by other people (viro,
torvalds, adaplas) in the meantime. Furthermore,

- all remaining sparse warnings were fixed (mainly caused by the ROM code)

- problems with very old and brand new BIOSes from SiS were fixed,

- LCD setup was simplified, allowing more display modes than before,

- UMC/charter bridge type handling was added,

- a code clean-up was performed, the new FB_BLANK-flags were taken over,
VBLANK status info was corrected, etc.
