[RESEND PATCH v4 0/5] Clean up huge vmap and ioremap code

[Will Deacon <will.deacon@arm.com>]

Hi all,

This is a resend of version four of the patches I previously posted here:

  v1: http://lkml.kernel.org/r/1536747974-25875-1-git-send-email-will.deacon@arm.com
  v2: http://lkml.kernel.org/r/1538478363-16255-1-git-send-email-will.deacon@arm.com
  v3: http://lkml.kernel.org/r/1539188584-15819-1-git-send-email-will.deacon@arm.com
  v4: http://lkml.kernel.org/r/1543252067-30831-1-git-send-email-will.deacon@arm.com

The only difference from v4 is that I have added Sean's Reviewed-by to the
core change.

Andrew, please can you take this via your tree for 4.21?

Thanks,

Will
