Subject: [PATCH v2 0/2] ia64: prevent irq migration race in __cpu_disable path
Date: Mon, 9 Feb 2009 11:13:38 -0700 [thread overview]
Message-ID: <20090209181338.GD19064@ldl.fc.hp.com> (raw)
This is v2 of my attempt to prevent an oops while offlining CPUs.
The change is that the patch becomes a full revert of Paul's
original patch, along with a long changelog that explains the
situation as best as I can determine. It's not 100% satisfactory
to me right now, but the testing we've done supports the patch.
The 2nd patch in the series is mostly cosmetic, and removes a
redundant call to cpu_clear() that we no longer need().
Tony, if you agree with the rationale in 1/2, then this series is
a candidate for .29.
stable team, if Tony pushes upstream for .29, then this series
should be applied to the .27 and .28 stable series.
Thanks.
