The old patch series was queued in KVM/queue for a while and finally

What are fixed in this series:
1. An missing of -1: if ((entry->eax & 0xff) != (1 << (depth_bit - 1)))
2. Removed exit bit check in cpu_has_vmx_arch_lbr(void), moved it to
setup_vmcs_config().
3. A redundant check kvm_cpu_cap_has(X86_FEATURE_ARCH_LBR) in
kvm_check_cpuid().
4. KUT/selftest failures due to lack of MSR_ARCH_LBR_CTL and
MSR_ARCH_LBR_DEPTH in kvm_set_msr_common() before validate pmu msrs.
5. Calltrace in L1 when L1 tried to vmcs_write64(GUEST_IA32_LBR_CTL,
0) in vmx_vcpu_reset(), use cpu_has_vmx_arch_lbr() instead.
6. Removed VM_ENTRY_LOAD_IA32_LBR_CTL and VM_EXIT_CLEAR_IA32_LBR_CTL
from exec_control in nested case.
Hi, Sean,
Could you kindly review this post and give some comments on the series
so that I can prepare next version?
Thanks!
