  powerpc/mm/hash/4k: Free hugetlb page table caches correctly. (2018-06-20 09:13:25 +1000)

- ------------------------------------------------------------------
powerpc fixes for 4.18 #2

 - 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.
