Patch series "mm/highmem: Fix fallout from generic kmap_local
conversions".

The kmap_local conversion wreckaged sparc, mips and powerpc as it missed
some of the details in the original implementation.

This patch (of 4):

The recent conversion to the generic kmap_local infrastructure failed to
assign the proper pre/post map/unmap flush operations for sparc.

Sparc requires cache flush before map/unmap and tlb flush afterwards.
