  KVM: x86: Consolidate guest enter/exit logic to common helpers (2021-05-05 22:54:12 +0200)

----------------------------------------------------------------
- Fix guest vtime accounting so that ticks happening while the guest is running
can also be accounted to it. Along with a consolidation to the guest-specific context
tracking helpers.

- Provide for the host NMI handler running after a VMX VMEXIT to be able to run
on the kernel stack correctly.

- Initialize MSR_TSC_AUX when RDPID is supported and not RDTSCP (virt relevant -
  real hw supports both)

- A code generation improvement to TASK_SIZE_MAX through the use of alternatives

- The usual misc. and related cleanups and improvements
