While the MMUCR.URB and ITLB/UTLB differentiation works fine for all SH-4 and later TLBs, these features are absent on SH-3. This splits out local_flush_tlb_all() in to SH-4 and PTEAEX copies while restoring the old SH-3 one, subsequently fixing up the build. This will probably want some further reordering and tidying in the future, but that's out of scope at present. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
