[PATCH 0/2] Last level (leaf) TLBI support

[Catalin Marinas]

AArch64 introduces TLBI operations that only invalidate the last level
of a page table (block entry). The first patch in the series is just a
minor clean-up to avoid defining too many functions. The second patch
introduces the last level TLBI support for flush_tlb_page() and
tlb_flush(). The flush_tlb_range() function cannot be changed since it
is used in THP code for collapsing multiple small pages into a huge
page.

Catalin Marinas (2):
  arm64: Clean up __flush_tlb(_kernel)_range functions
  arm64: Use last level TLBI for user pte changes
