fadd03c # Author: Linus Torvalds <torvalds@linux-foundation.org> # Date: Sat Jun 23 21:13:05 2018 +0800 # # Merge tag 'powerpc-4.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux # # Pull powerpc fixes from Michael Ellerman: # # - a fix for hugetlb with 4K pages, broken by our recent changes for # split PMD PTL. # # - set the correct assembler machine type on e500mc, needed since # binutils 2.26 introduced two forms for the "wait" instruction. # # - a fix for potential missed TLB flushes with MADV_[FREE\|DONTNEED] etc. # and THP on Power9 Radix. # # - three fixes to try and make our panic handling more robust by hard # disabling interrupts, and not marking stopped CPUs as offline because # they haven't been properly offlined. # # - three other minor fixes. # # Thanks to: Aneesh Kumar K.V, Michael Jeanson, Nicholas Piggin. # # * tag 'powerpc-4.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: # powerpc/mm/hash/4k: Free hugetlb page table caches
