Don't know how realistic this can hit. * x86/fsgsbase: Fix Xen PV support * x86/process/64: Make save_fsgs_for_kvm() ready for FSGSBASE - these two are for VMMs. Some of these are already included in our azure kernels. 5.8 doesn't need them because we already synced with upstream while preparing it. [Test Case] Since we are syncing with mainline a boot test and a regression test in ACC instances should be enough to confirm the changes are working. Since these instances are not publicly available yet, Msft is helping us to test this changes. [Where problems could occur] This affects the SGX driver that is only available on ACC instances (which is not widely used yet).
