Subject: [RFC][PATCH 0/2] convert s390 to generic mmu_gather
Date: Tue, 18 Sep 2018 14:51:49 +0200 [thread overview]
Message-ID: <20180918125151.31744-1-schwidefsky@de.ibm.com> (raw)
Hi Peter,
as an add-on for the TLB flushing changes two patches to make
s390 use the generic mmu_gather code as well. I let it run for
a few hours with several TLB stress tests, no fallout so far.
It certainly can use more testing but it looks ok to me.
