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.
