Commit 2ccdd1e77d doesn't add
v7wbi_possible_flags and v7wbi_always_flags to possible_tlb_flags and
always_tlb_flags. This causes the L2 cache flush in clean_pmd_entry()
(intended for Feroceon only) to execute on ARMv7, and the CPU hangs.
This patch is required for OMAP3 boards to boot.

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).

The existing code tries to get the pmd for the temporary page table
by doing:
pgd = pgd_alloc(&init_mm);
pmd = pmd_offset(pgd, PHYS_OFFSET);
Since we have a two level page table, pmd_offset() is a no-op, so
this just has a casting effect from a pgd to a pmd - the address
argument is unused. So this can't work.
Normally, we'd do:
pgd = pgd_offset(&init_mm, PHYS_OFFSET);
...
pmd = pmd_offset(pgd, PHYS_OFFSET);
to get the pmd you want. However, pgd_offset() takes the mm_struct,
not the (unattached) pgd we just allocated. So, instead use:
pgd = pgd_alloc(&init_mm);
pmd = pmd_offset(pgd + pgd_index(PHYS_OFFSET), PHYS_OFFSET);
