Paul Mundt	0906a3ad33	sh: Fix up and optimize the kmap_coherent() interface. This fixes up the kmap_coherent/kunmap_coherent() interface for recent changes both in the page fault path and the shared cache flushers, as well as adding in some optimizations. One of the key things to note here is that the TLB flush itself is deferred until the unmap, and the call in to update_mmu_cache() itself goes away, relying on the regular page fault path to handle the lazy dcache writeback if necessary.

Paul Mundt	c0b96cf639	sh: Provide _PAGE_SPECIAL for 32-bit. Allocate one of the unused PTE bits for _PAGE_SPECIAL directly. This is prep work for fast gup and the zero page revival. Signed-off-by: Paul Mundt <lethal@linux-sh.org>	2009-07-22 16:50:57 +09:00
Paul Mundt	f15cbe6f1a	sh: migrate to arch/sh/include/ This follows the sparc changes `a439fe51a1`. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault.
