[PATCH v3 0/5] Clean up huge vmap and ioremap code

Hi all,

This is version three of the patches I previously posted here:

  v1: http://lkml.kernel.org/r/1536747974-25875-1-git-send-email-will.deacon@xxxxxxx
  v2: http://lkml.kernel.org/r/1538478363-16255-1-git-send-email-will.deacon@xxxxxxx

The only changes since v2 are to the commit messages.

All feedback welcome,



Will Deacon (5):
  ioremap: Rework pXd_free_pYd_page() API
  arm64: mmu: Drop pXd_present() checks from pXd_free_pYd_table()
  x86/pgtable: Drop pXd_none() checks from pXd_free_pYd_table()
  lib/ioremap: Ensure phys_addr actually corresponds to a physical
  lib/ioremap: Ensure break-before-make is used for huge p4d mappings
