[PATCH v3 0/8] huge vmalloc mappings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Not tested on x86 or arm64, would appreciate a quick test there so I can
ask Andrew to put it in -mm. Other option is I can disable huge vmallocs
for them for the time being.

Since v2:
- Rebased on vmalloc cleanups, split series into simpler pieces.
- Fixed several compile errors and warnings
- Keep the page array and accounting in small page units because
  struct vm_struct is an interface (this should fix x86 vmap stack debug
  assert). [Thanks Zefan]

Nicholas Piggin (8):
  mm/vmalloc: fix vmalloc_to_page for huge vmap mappings
  mm: apply_to_pte_range warn and fail if a large pte is encountered
  mm/vmalloc: rename vmap_*_range vmap_pages_*_range
  lib/ioremap: rename ioremap_*_range to vmap_*_range
  mm: HUGE_VMAP arch support cleanup
  mm: Move vmap_range from lib/ioremap.c to mm/vmalloc.c
  mm/vmalloc: add vmap_range_noflush variant
  mm/vmalloc: Hugepage vmalloc mappings
