[GIT PULL] arm64: fix for -rc3

[Will Deacon]

Hi Linus,

Just one small fix here, preventing a VM_WARN_ON when a !present PMD/PUD
is "freed" as part of a huge ioremap() operation. The correct behaviour
is to skip the free silently in this case, which is a little weird (the
function is a bit of a misnomer), but it follows the x86 implementation.

I also renewed the expiry dates on my gpg subkeys this week, so you might
need to re-fetch them if you can find a working keyserver.

Cheers,

Will
