This series to add support for Hygon CPUs and fix 11 KVM selftest failures
on Hygon architecture.

Patch 1 add CPU vendor detection for Hygon and add a global variable
"host_cpu_is_hygon" to identify if the test is running on a Hygon CPU.
It is the prerequisite for the following fixes.

Patch 2 fix x86/fix_hypercall_test test failure by altering the hypercall
instruction on Hygon CPUs.

Patch 3 fix following test failures by avoiding using the reserved
memory regions on Hygon CPUs.
- access_tracking_perf_test
- demand_paging_test
- dirty_log_perf_test
- dirty_log_test
- kvm_page_table_test
- memslot_modification_stress_test
- pre_fault_memory_test
- x86/dirty_log_page_splitting_test

Patch 4 fix x86/pmu_event_filter_test test failure by allowing the tests
for Hygon CPUs.

Patch 5 fix x86/msrs_test test failure by fixing the expectation while
writing the MSR_TSC_AUX reserved bits without RDPID support.

Zhiquan Li (5):
  KVM: x86: selftests: Add CPU vendor detection for Hygon
  KVM: x86: selftests: Alter the instruction of hypercall on Hygon
  KVM: x86: selftests: Avoid failures due to reserved memory address
    regions on Hygon
