  KVM: selftests: Compare insn opcodes directly in fix_hypercall_test (2022-09-29 12:54:02 -0400)

----------------------------------------------------------------
A small fix to the reported set of supported CPUID bits, and selftests fixes:

* Skip tests that require EPT when it is not available

* Do not hang when a test fails with an empty stack trace

* avoid spurious failure when running access_tracking_perf_test in a KVM guest

* work around GCC's tendency to optimize loops into mem*() functions, which
  breaks because the guest code in selftests cannot call into PLTs

* fix -Warray-bounds error in fix_hypercall_test
