Calling the undefined instruction handler functions with a
spinlock held is a recipe for must_sleep() warnings. Avoid it.

Convert the existing dma_sync_single_for_* APIs to the new range based

OMAP at least gets the return type(s) for the DMA translation functions
wrong, which can lead to subtle errors. Avoid this by moving the DMA
translation functions to asm/dma-mapping.h, and converting them to
inline functions.
Fix the OMAP DMA translation macros to use the correct argument and
result types.
Also, remove the unnecessary casts in dmabounce.c.

This patch will truncate and/or ignore memory banks if their kernel
direct mappings would (partially) overlap with the vmalloc area or
the mappings between the vmalloc area and the address space top, to
prevent crashing during early boot if there happens to be more RAM
installed than we are expecting.
Since the start of the vmalloc area is not at a fixed address (but
the vmalloc end address is, via the per-platform VMALLOC_END define),
a default area of 128M is reserved for vmalloc mappings, which can
be shrunk or enlarged by passing an appropriate vmalloc= command line
option as it is done on x86.
On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe000000,
two 512M RAM banks and vmalloc=128M (the default), this patch gives:
Truncating RAM at 20000000-3fffffff to -35ffffff (vmalloc region overlap).
Memory: 512MB 352MB = 864MB total
On a board with a 3:1 user:kernel split, VMALLOC_END at 0xfe800000,
two 256M RAM banks and vmalloc=768M, this patch gives:
Truncating RAM at 00000000-0fffffff to -0e7fffff (vmalloc region overlap).
Ignoring RAM at 10000000-1fffffff (vmalloc region overlap).

Export the four red SATA LEDs on the QNAP TS-409 that are connected
through gpio. Since the boot loader apparently sets the SATA LEDs 2-4
to red and the SATA LED can only be red or green (but not both),
exporting the red SATA LEDs (which automatically turns them off upon
boot) makes the green SATA presence/activity indication visible.

The cats_map_irq() function in the Simtec CATS support
code is mapping IRQ 255 (invalid IRQ) into what is a
supposedly valid interrupt numner which can cause problems
with other devices then seeing an interrupt they cannot
claim.
If the IRQ number if >= 255, then return -1 as this is not
something we can map.
