KVM: SVM: load control fields from VMCB12 before checking them
(CVE-2021-29657).
It also adds the following fixes:
- x86/fpu/64: Don't FNINIT in kernel_fpu_begin()
- Revert "iommu/amd: Fix performance counter initialization"
- iommu/amd: Remove performance counter pre-initialization test
- hwmon: (amd_energy) Add AMD family 19h model 30h x86 match
- hwmon: (amd_energy) Use unified function to read energy data
- hwmon: (amd_energy) Restore visibility of energy counters
For other upstream fixes, see the referenced changelogs.
