This fixes up the nommu build with a stub definition for
__flush_tlb_global(), now used by the reboot code.

Paul Mundt 56d45b62ce sh: Fix up nommu build for out-of-line pgtable changes.
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.

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 aae4d1428c sh: consolidate nommu stubs in arch/sh/mm/nommu.c.
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.
