* sh: stub __flush_tlb_global() definition for nommu.Paul Mundt2010-08-161-0/+4
| | | | | | | This fixes up the nommu build with a stub definition for __flush_tlb_global(), now used by the reboot code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up nommu build for out-of-line pgtable changes.Paul Mundt2010-01-061-0/+4
| | | | | | | pgtable_cache_init() has been moved out-of-line, so we also need a dummy definition for it on nommu to fix up the build. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up and optimize the kmap_coherent() interface.Paul Mundt2009-09-031-1/+1
| | | | | | | | | | | | | 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.

* sh: consolidate nommu stubs in arch/sh/mm/nommu.c.Paul Mundt2009-08-151-0/+96
These were previous littered around tlb-nommu.c and pg-nommu.c, though at this point there are more stubs than are strictly TLB or page op related, so just consolidate them in a single nommu.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
