[PATCH v8 0/5] KVM: selftests: Add AMD PMU Host/Guest test

[Sean Christopherson]

This is the selftests portion of the mediated PMU Host-Only/Guest-Only series.
My plan is to get this into 7.2-rc1, but after the other KVM x86 pull requests
have been merged by Paolo (several unpleasant conflicts across multiple
branches).  I'll either send a separate pull request, or see if Paolo wants
to apply them directly.

v8:
 - Add a kvm_is_mediated_pmu_enabled() helper.
 - Drop the AMD Family check.

v7: https://lore.kernel.org/all/20260527234711.4175166-1-yosry@xxxxxxxxxx

Jim Mattson (1):
  KVM: selftests: Add svm_pmu_host_guest_test for Host-Only/Guest-Only
    bits

Sean Christopherson (1):
  KVM: selftests: Add a helper to query enable_mediated_pmu module param

Yosry Ahmed (3):
  KVM: selftests: Refactor allocating guest stack into a helper
  KVM: selftests: Allocate a dedicated guest page for x86 L2 guest stack
  KVM: selftests: Drop L1-provided stacks for L2 guests on x86
