In patch 1, an expanded context switching comment, and in patch 2, an adjusted commit message and movement into __initdata. I've also closed out #90, which closes one of the release blockers. All other bugs can wait until 4.18, including the totally bizarre one where using cpuid="host:virt-ssbd=1" in the xl.cfg file causes IBRS to become hidden. I confirmed this was pre-existing behaviour, but haven't investigated further. ~Andrew
