Patch from Deepak Saxena

Supersedes 2226/1

According to the IXP Programmer's Reference Manual, a read from
IRQ_STATUS can only return '1' for IRQ sources that have been
explicitly enabled in IRQ_ENABLE. So if we never enable 'invalid'
IRQ sources, we don't actually have to mask off IRQ_STATUS with
IXP2000_VALID_IRQ_MASK.

- nothing clever here: the most noticeable change is the change of
  returned value for (*init_setup) in struct ide_pci_device_s which
  goes from void to int. Anything else is editing and checking for
  errors in the output of the compiler;
- pci_disable_device() added for the error path in pci_init_sgiioc4();
- BUG() removed in amd74xx_probe(): good old printk() is enough.

- no need to overwrite the status code returned by the pci_xyz() functions;
- jump into the new century and use DMA_32BIT_MASK;
- misc cleanup in the error paths. It should not add a huge value in
  ide_pci_enable() due to the FIXME comment but it should not bite too hard
  either.

ide_setup_pci_controller() puts the device in a PCI enabled state.
The patch adds a small helper to balance it when things go wrong.

Actually the helper does not *exactly* balance the setup: if it can
not do a better job, ide_setup_pci_controller() may only enable some
BARS whereas the new counterpart will try to disable everything.

- Change the return value and the prototype of do_ide_setup_pci_device
  Due to lack of appropriate return status code, the current clients of
  do_ide_setup_pci_device() can not distinguish a failing invocation
  from a successfull one. The patch modify do_ide_setup_pci_device() so
  that it can propagate some of the errors from the lower layers.

- Make ide_setup_pci_device() aware of the change and propagate the news
  itself. I only gave a quick sight to create_proc_ide_interfaces() (and
  ide_remove_proc_entries()) but they do seem sane and it should not matter
  if it fails or not.

- ide_setup_pci_devices(): mostly the same thing than ide_setup_pci_device().

Several IDE drivers return positive values as errors in the PCI setup
code. Unfortunately the PCI layer considers positive values as success
so the driver skips the device but still claims it and things then go
downhill.

Patch from George G. Davis

Adds support for Thumb ld/st alignment fault fixups via conversion of
Thumb ld/st instruction forms into equivalent ARM instructions and
reusing ARM alignment fault handler for Thumb instructions. This
implementation was inspired by and initially based on the algorithm
found in gdb/sim/arm/thumbemu.c.

I've backed out the silly 'T' suffix on PC in this version as requested
by RMK. At this point, I prefer to avoid making any of the other changes
discussed, e.g. dump_instr() for bad instruction cases, in order to get
the basic Thumb support change committed.

Thanks!

This patch syncs the mainline kernel with the linux-omap tree.
The highlights of the patch are:
- Add OMAP board specific low-level init functions for smc91x Ethernet
- DMA audio functions by Nishant Menon
- Remove references to OMAP specific serial.h

This is an updated version of ARM patch 2331/1 with extra comments
added to the omap_get_dma_src_pos() and omap_get_dma_dst_pos() functions
as recommended by RMK.
