Subject: [GIT PULL] KVM: x86: Selftests changes for 6.19

The highlights are Jim's LA57 nested VMX test, and Yosry's many changes to
extend nested VMX tests to also cover nested SVM.

The following changes since commit 211ddde0823f1442e4ad052a2f30f050145ccada:

  KVM: selftests: Make sure vm->vpages_mapped is always up-to-date (2025-11-21 10:17:05 -0800)

----------------------------------------------------------------
KVM selftests changes for 6.19:

 - Fix a math goof in mmu_stress_test when running on a single-CPU system/VM.

 - Forcefully override ARCH from x86_64 to x86 to play nice with specifying
   ARCH=x86_64 on the command line.

 - Extend a bunch of nested VMX to validate nested SVM as well.

 - Add support for LA57 in the core VM_MODE_xxx macro, and add a test to
   verify KVM can save/restore nested VMX state when L1 is using 5-level
   paging, but L2 is not.

 - Clean up the guest paging code in anticipation of sharing the core logic for
   nested EPT and nested NPT.
