Date: Thu Aug 23 14:55:01 2018 -0700 # # Merge branch 'tlb-fixes' # # Merge fixes for missing TLB shootdowns. # # This fixes a couple of cases that involved us possibly freeing page # table structures before the required TLB shootdown had been done. # # There are a few cleanup patches to make the code easier to follow, and # to avoid some of the more problematic cases entirely when not necessary. # # To make this easier for backports, it undoes the recent lazy TLB # patches, because the cleanups and fixes are more important, and Rik is # ok with re-doing them later when things have calmed down. # # The missing TLB flush was only delayed, and the wrong ordering only # happened under memory pressure (and in theory under a couple of other # fairly theoretical situations), so this may have been all very unlikely # to have hit people in practice. # # But getting the TLB shootdown wrong is _so_ hard to debug and see that I # consider this a crticial fix. # # Many thanks to Jann Horn for having debugged this. # # * tlb-fixes: # x86/mm: Only use tlb_remove_table() for paravirt # mm: mmu_notifier fix for tlb_end_vma # mm/tlb, x86/mm: Support invalidating TLB caches for RCU_TABLE_FREE # mm/tlb: Remove tlb_remove_table() non-concurrent condition # mm: move tlb_table_flush to tlb_flush_mmu_free # x86/mm/tlb: Revert the recent lazy TLB patches # < /opt/cross/kisskb/gcc-4.6.3-nolibc/i386-linux/bin/i386-linux-gcc --version #
