[PATCH 0/5] Minor cleanups to kernel pte handling

[linux@arm.linux.org.uk (Russell King - ARM Linux)]

This series of five patches cleans up the pte handling for users of
the 'TOP_PTE' - those CPUs which require special handling of cache
aliases and the like.

TOP_PTE() always was ugly, so this patch set gets rid of it, in favour
of a couple of helper functions (set_top_pte() and get_top_pte()).
set_top_pte() contains the necessary local TLB flush to ensure that
the update will be seen by the MMU.

We also centralize the virtual addresses used for these mappings into
arch/arm/mm/mm.h.

Finally, we transform pfn_pte(page_to_pfn(page), prot) to
mk_pte(page, prot) as we don't need to open-code this operation, and
we have this helper anyway.
