[Devel] [PATCH 00/16] add tsc_scale and fix VM pause/resume

[Roman Kagan]

From: Denis Plotnikov <dplotnikov at virtuozzo.com>

The set of patches:
1. adds tsc_scaling functionality for VMX
2. generalizes a number of functions responsible for tsc writing and
   reading
3. fix VM pause/resume issue #PSBM-54338 by switching to using
   of cached tsc_offset

Haozhong Zhang (12):
  KVM: x86: Collect information for setting TSC scaling ratio
  KVM: x86: Add a common TSC scaling ratio field in kvm_vcpu_arch
  KVM: x86: Add a common TSC scaling function
  KVM: x86: Replace call-back set_tsc_khz() with a common function
  KVM: x86: Replace call-back compute_tsc_offset() with a common
    function
  KVM: x86: Move TSC scaling logic out of call-back adjust_tsc_offset()
  KVM: x86: Move TSC scaling logic out of call-back read_l1_tsc()
  KVM: x86: Use the correct vcpu's TSC rate to compute time scale
  KVM: VMX: Enable and initialize VMX TSC scaling
  KVM: VMX: Setup TSC scaling ratio when a vcpu is loaded
  KVM: VMX: Use a scaled host TSC for guest readings of MSR_IA32_TSC
  KVM: VMX: Dump TSC multiplier in dump_vmcs()

Luiz Capitulino (2):
  kvm: x86: add tsc_offset field to struct kvm_vcpu_arch
  kvm: x86: drop read_tsc_offset()

Paolo Bonzini (2):
  KVM: x86: declare a few variables as __read_mostly
  KVM: x86: drop TSC offsetting kvm_x86_ops to fix KVM_GET/SET_CLOCK
