BugLink: https://bugs.launchpad.net/bugs/1792957 == SRU Justification == This patch has been requested by IBM. It provides a mode where all vCPUs on a core must be the same VM. This is intended for use in security-conscious settings where users are concerned about possible side-channel attacks between threads which could perhaps enable one VM to attack another VM on the same core, or the host. == Fix == linux-next commit: aa2278644ae5 ("KVM: PPC: Book3S HV: Provide mode where all vCPUs on a core must be the same VM") == Regression Potential == Low. Changes limited to powerpc. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug.
