Subject: [PATCH 0/3] fix free pmd/pte page handlings on x86
Date: Mon, 30 Apr 2018 11:59:22 -0600 [thread overview]
Message-ID: <20180430175925.2657-1-toshi.kani@hpe.com> (raw)
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.
