Subject: [PATCH v2 0/4] huge vmalloc mappings
Date: Mon, 13 Apr 2020 22:52:59 +1000	[thread overview]
Message-ID: <20200413125303.423864-1-npiggin@gmail.com> (raw)

We can get a significant win with larger mappings for some of the big
global hashes.

Since RFC, relevant architectures have added p?d_leaf accessors so no
real arch changes required, and I changed it not to allocate huge
mappings for modules and a bunch of other fixes.

Nicholas Piggin (4):
  mm/vmalloc: fix vmalloc_to_page for huge vmap mappings
  mm: Move ioremap page table mapping function to mm/
  mm: HUGE_VMAP arch query functions cleanup
  mm/vmalloc: Hugepage vmalloc mappings
