Subject: [PATCH v2 0/7] Refactor handling flow of SET_CPUID* 
Date:   Tue, 23 Jun 2020 19:58:09 +0800
Message-Id: <20200623115816.24132-1-xiaoyao.li@intel.com>

Precedence: bulk

This serial is the extended version of
https://lkml.kernel.org/r/20200528151927.14346-1-xiaoyao.li@intel.com

First two patches are bug fixing, and the others aim to refactor the flow
of SET_CPUID* as:

1. cpuid check: check if userspace provides legal CPUID settings;

2. cpuid update: Update some special CPUID bits based on current vcpu
                 state, e.g., OSXSAVE, OSPKE, ...

3. update vcpu model: Update vcpu model (settings) based on the final CPUID
                      settings. 


v2:
 - rebase to kvm/queue: a037ff353ba6 ("Merge branch 'kvm-master' into HEAD")
 - change the name of kvm_update_state_based_on_cpuid() to
   kvm_update_vcpu_model() [Sean]
 - Add patch 5 to rename kvm_x86_ops.cpuid_date() to
   kvm_x86_ops.update_vcpu_model()

v1:
https://lkml.kernel.org/r/20200529085545.29242-1-xiaoyao.li@intel.com


Xiaoyao Li (7):
  KVM: X86: Reset vcpu->arch.cpuid_nent to 0 if SET_CPUID fails
  KVM: X86: Go on updating other CPUID leaves when leaf 1 is absent
  KVM: X86: Introduce kvm_check_cpuid()
  KVM: X86: Split kvm_update_cpuid()
  KVM: X86: Rename cpuid_update() to update_vcpu_model()
  KVM: X86: Move kvm_x86_ops.update_vcpu_model() into
    kvm_update_vcpu_model()
  KVM: X86: Move kvm_apic_set_version() to kvm_update_vcpu_model()
