Linus Torvalds 20e0d85764 Merge tag 'snp_cache_coherency' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
- Add a mitigation for a cache coherency vulnerability when running an
   SNP guest which makes sure all cache lines belonging to a 4K page are
   evicted after latter has been converted to a guest-private page

[ SNP: Secure Nested Paging - not to be confused with Single Nucleotide
  Polymorphism, which is the more common use of that TLA. I am on a
  mission to write out the more obscure TLAs in order to keep track of
  them.

  Because while math tells us that there are only about 17k different
  combinations of three-letter acronyms using English letters (26^3), I
  am convinced that somehow Intel, AMD and ARM have together figured out
  new mathematics, and have at least a million different TLAs that they
  use.   - Linus ]
