[PATCH 0/5] Add support for IBRS & IBPB KVM support.

[Ashok Raj]

The following patches are based on v3 from Tim Chen

https://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg1582043.html

This patch set supports exposing MSR_IA32_SPEC_CTRL and MSR_IA32_PRED_CMD
for user space.

Thomas is steam blowing v3 :-).. but I didn't want to keep holding this
much longer for the rebase to be complete in tip/x86/pti.

Ashok Raj (4):
  x86/ibrs: Introduce native_rdmsrl, and native_wrmsrl
  x86/ibrs: Add new helper macros to save/restore MSR_IA32_SPEC_CTRL
  x86/ibrs: Add direct access support for MSR_IA32_SPEC_CTRL
  x86/feature: Detect the x86 feature Indirect Branch Prediction Barrier

Paolo Bonzini (1):
  x86/svm: Direct access to MSR_IA32_SPEC_CTRL
