Subject: [PATCH v2 0/5] Clean up huge vmap and ioremap code

Hi all,

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

  http://lkml.kernel.org/r/1536747974-25875-1-git-send-email-will.deacon@arm.com

Changes since v1 include:

  * Fixed increment of the physical address around the mapping loops
  * Added Reviewed-by tags from Toshi

All feedback welcome,

Will

  x86: pgtable: Drop pXd_none() checks from pXd_free_pYd_table()
  lib/ioremap: Ensure phys_addr actually corresponds to a physical
    address
  lib/ioremap: Ensure break-before-make is used for huge p4d mappings
