Subject: [PATCH 06/12] KVM: PPC: Book3S HV: Remove bogus update of thread IDs in HV KVM
Date: Tue, 28 Aug 2012 22:35:42 +1000 [thread overview]
Message-ID: <20120828123542.GG7258@bloggs.ozlabs.ibm.com> (raw)
In-Reply-To: <20120828123043.GA7258@bloggs.ozlabs.ibm.com>
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
When making a vcpu non-runnable we incorrectly changed the
thread IDs of all other threads on the core, just remove that
code.
