  KVM: selftests: Increase robustness of LLC cache misses in PMU counters test (2024-06-28 08:44:03 -0700)

----------------------------------------------------------------
KVM selftests for 6.11

 - Remove dead code in the memslot modification stress test.

 - Treat "branch instructions retired" as supported on all AMD Family 17h+ CPUs.

 - Print the guest pseudo-RNG seed only when it changes, to avoid spamming the
   log for tests that create lots of VMs.

 - Make the PMU counters test less flaky when counting LLC cache misses by
   doing CLFLUSH{OPT} in every loop iteration.
