# Merge: 7ab366e 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.
