Subject: [PATCH 0/2] Fix resume failure due to PCID
Date: Wed, 6 Sep 2017 19:54:52 -0700 [thread overview]
Message-ID: <cover.1504752689.git.luto@kernel.org> (raw)
Patch 1 is the fix. Patch 2 is a comment that would have kept me from
chasing down a false lead.
I've tested patch 2 using CPU hotplug and suspend/resume. I haven't
tested hibernation or kexec because I don't know how. (If I do
systemctl hibernate on my laptop, it happily writes out a hiberation
image somewhere and then it equally happily ignores it on the next
boot. I don't know how to test kexec.)
I haven't tested the 32-bit version. I'll try to get to that
tomorrow.
