Linus Torvalds 5e2d059b52 powerpc updates for 4.19
Notable changes:
 
  - A fix for a bug in our page table fragment allocator, where a page table page
    could be freed and reallocated for something else while still in use, leading
    to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for
    a powerpc only refcount.
 
  - Fixes to our pkey support. Several are user-visible changes, but bring us in
    to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer
    for reporting many of these.
 
  - A series to improve the hvc driver & related OPAL console code, which have
    been seen to cause hardlockups at times. The hvc driver changes in particular
    have been in linux-next for ~month.
 
  - Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
 
  - Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use
    anywhere other than as a paper weight.
 
  - An optimised memcmp implementation using Power7-or-later VMX instructions
 
  - Support for barrier_nospec on some NXP CPUs.
 
  - Support for flushing the count cache on context switch on some IBM CPUs
    (controlled by firmware), as a Spectre v2 mitigation.
 
  - A series to enhance the information we print on unhandled signals to bring it
    into line with other arches, including showing the offending VMA and dumping
    the instructions around the fault.
