KVM selftests updates for 6.2

Browse source

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; atomics 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.
