From cd68098bcedd432f21013b2a3b0737b9222da363 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 8 Jul 2014 17:10:45 +1000 Subject: powerpc: Clean up MMU_FTRS_A2 and MMU_FTR_TYPE_3E In fb5a515704d7 "powerpc: Remove platforms/wsp and associated pieces", we removed the last user of MMU_FTRS_A2. So remove it. MMU_FTRS_A2 was the last user of MMU_FTR_TYPE_3E, so remove it also. This leaves some unreachable code in mmu_context_nohash.c, so remove that also.
