Linus Torvalds f9a705ad1c ARM:
- New page table code for both hypervisor and guest stage-2
 - Introduction of a new EL2-private host context
 - Allow EL2 to have its own private per-CPU variables
 - Support of PMU event filtering
 - Complete rework of the Spectre mitigation
 
 PPC:
 - Fix for running nested guests with in-kernel IRQ chip
 - Fix race condition causing occasional host hard lockup
 - Minor cleanups and bugfixes
 
 x86:
 - allow trapping unknown MSRs to userspace
 - allow userspace to force #GP on specific MSRs
 - INVPCID support on AMD
 - nested AMD cleanup, on demand allocation of nested SVM state
 - hide PV MSRs and hypercalls for features not enabled in CPUID
 - new test for MSR_IA32_TSC writes from host and guest
 - cleanups: MMU, CPUID, shared MSRs
 - LAPIC latency optimizations ad bugfixes
 
 For x86, also included in this pull request is a new alternative and
 (in the future) more scalable implementation of extended page tables
 that does not need a reverse map from guest physical addresses to
 host physical addresses.  For now it is disabled by default because
 it is still lacking a few of the existing MMU's bells and whistles.
 However it is a very solid piece of work and it is already available
 for people to hammer on it.
