From be97d758e5728099e95fe229866d5c6c900d3092 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 2 Apr 2010 16:13:27 +0900 Subject: sh: Fix up the SH-3 build for recent TLB changes. 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.
