This adds DMA mmap() support for the ARM architecture, as discussed
around March 2003 on the linux-arch and linux-kernel mailing lists.

Subsystems such as ALSA (for sample ring buffers) and video drivers
(for framebuffers in system memory) require this infrastructure to
provide userspace with an architecture clean method to mmap these
memory areas.

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!

Patch from Tony Lindgren

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.

Patch from George G. Davis

Convert ARM proc files to use manifest constants defined in pgtable.h
and domain.h. This is a prelude to allow renumbering domains. The
domain renumbering is required to implement support for ARMv6 MMU
super sections where domain 0 is implied. Although this is technically
only required for ARMv6, it seemed reasonable to clean up all proc
files while here.

I did a test build with and without this patch applied and confirmed
that all proc file binaries are unchanged when this patch is applied.

Repairs the breakage introduced in gcc4 fixes.  Original had expanded
to

	((struct zatm_dev *)(dev)->dev_data) = zatm_dev;

and that's what gcc4 had complained about (cast-as-lvalue).  Proper fix is,
of course,

	dev->dev_data = zatm_dev;

What we have in 2.6.10 is

	dev = (struct atm_dev *)zatm_dev;

which doesn't cause complaints, but doesn't do anything good (leak + corruption
at the very least).

Add a driver that implements the (IPoIB) IP-over-InfiniBand protocol.
This is a network device driver of type ARPHRD_INFINIBAND (and
addr_len INFINIBAND_ALEN bytes).

The ARP/ND implementation for this driver is not completely
straightforward, because InfiniBand requires an additional path lookup
be performed (through an IB-specific mechanism) after a remote
hardware address has been resolved.  We are very open to suggestions
of a better way to handle this than the current implementation.

Although IB has a special multicast group join mode intended to
support IP multicast routing (non member join), no means to identify
different multicast styles has yet been determined, so all joins by
the driver are currently full member joins.  We are looking for
guidance in how to solve this.

The IPoIB protocol/encapsulation is described in the Internet-Drafts
