Merge tag 'kvm-selftests-6.2-1' of https://github.com/kvm-x86/linux into HEAD

KVM selftests updates for 6.2

perf_util:
 - Add support for pinning vCPUs in dirty_log_perf_test.
 - Add a lightweight psuedo RNG for guest use, and use it to randomize
   the access pattern and write vs. read percentage in the so called
   "perf util" tests.
 - Rename the so called "perf_util" framework to "memstress".

ucall:
 - Add a common pool-based ucall implementation (code dedup and pre-work
   for running SEV (and beyond) guests in selftests.
 - Fix an issue in ARM's single-step test when using the new pool-based
   implementation; LDREX/STREX don't play nice with single-step exceptions.

init:
 - Provide a common constructor and arch hook, which will eventually be
   used by x86 to automatically select the right hypercall (AMD vs. Intel).

x86:
 - Clean up x86's page tabe management.
 - Clean up and enhance the "smaller maxphyaddr" test, and add a related
   test to cover generic emulation failure.
 - Clean up the nEPT support checks.
 - Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
