[PATCH 0/3] fix free pmd/pte page handlings on x86

[Toshi Kani <toshi.kani@hpe.com>]

This series fixes x86 ioremap free page handlings when setting up
pud/pmd maps.

Patch 01 is from Chintan's v9 01/04 patch [1], which adds a new arg 'addr'.
This avoids merge conflicts with his series.

Patch 02 adds a TLB purge (INVLPG) to purge page-structure caches that
may be cached by speculation.  See patch 2/2 for the detals.

Patch 03 disables free page handling on x86-PAE to address BUG_ON reported
by Joerg.
