Subject: [GIT PULL] arm64: Fixes for -rc4
Date: Fri, 18 Oct 2019 00:43:49 +0100 [thread overview]
Message-ID: <20191017234348.wcbbo2njexn7ixpk@willie-the-truck> (raw)
Hi Linus,
Please pull these arm64 fixes for -rc4. The main thing here is a
long-awaited workaround for a CPU erratum on ThunderX2 which we have
developed in conjunction with engineers from Cavium/Marvell. At the moment,
the workaround is unconditionally enabled for affected CPUs at runtime
but we may add a command-line option to disable it in future if performance
numbers show up indicating a significant cost for real workloads.
The other fixes are summarised in the tag.
Note that the workaround code ended up being based on -rc2, so I had a
bit of a faff trying to generate the right diffstat for this pull request
after merging that branch into our fixes branch based on -rc1. In the end
I had to emulate the pull locally because I couldn't figure out how to
drive request-pull correctly despite the shortlog being correct. I'd love
to know what I should've done instead.
Thanks,
Will
