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.
