ARM: Eliminate decompressor -Dstatic= PIC hack
We used to build decompressors with -Dstatic= to avoid any local data
being generated. The problem is that local data generates GOTOFF
relocations, which means we can't relocate the data relative to the
text segment.
Global data, on the other hand, goes through the GOT, and can be
relocated anywhere.
Unfortunately, with the new decompressors, this presents a problem
since they declare static data within functions, and this leads to
stack overflow.
Fix this by separating out the decompressor code into a separate file,
and removing 'static' from BSS data in misc.c.
Also, discard the .data section - this means that should we end up
with read/write initialized data, the decompressor will fail to link
and the problem will be obvious.

MM: Pass a PTE pointer to update_mmu_cache() rather than the PTE itself
On VIVT ARM, when we have multiple shared mappings of the same file
in the same MM, we need to ensure that we have coherency across all
copies. We do this via make_coherent() by making the pages
uncacheable.
This used to work fine, until we allowed highmem with highpte - we
now have a page table which is mapped as required, and is not available
for modification via update_mmu_cache().
Ralf Beache suggested getting rid of the PTE value passed to
update_mmu_cache():
On MIPS update_mmu_cache() calls __update_tlb() which walks pagetables
to construct a pointer to the pte again. Passing a pte_t * is much
more elegant. Maybe we might even replace the pte argument with the
pte_t?
Ben Herrenschmidt would also like the pte pointer for PowerPC:
Passing the ptep in there is exactly what I want. I want that
-instead- of the PTE value, because I have issue on some ppc cases,
for I$/D$ coherency, where set_pte_at() may decide to mask out the
_PAGE_EXEC.
So, pass in the mapped page table pointer into update_mmu_cache(), and
remove the PTE value, updating all implementations and call sites to
suit.

The DMA API has the notion of buffer ownership; make it explicit in the
