Subject: [GIT PULL] arm64 fixes for -rc3
Date: Fri, 26 Nov 2021 13:22:46 +0000 [thread overview]
Message-ID: <20211126132245.GA20204@willie-the-truck> (raw)
Hi Linus,
When you get a chance, please can you pull these three arm64 fixes? The
main one is a fix to the way in which we evaluate the macro arguments to
our uaccess routines, which we _think_ might be the root cause behind
some unkillable tasks we've seen in the Android arm64 CI farm (testing is
ongoing). In any case, it's worth fixing.
Other than that, we've toned down an over-zealous VM_BUG_ON() and fixed
ftrace stack unwinding in a bunch of cases.
Please pull.
Thanks,
Will
