I split the previous patch series "[PATCH 0/4] add support for vNVDIMM" into two parts. This is the first part that enables clflushopt/clwb/pcommit instructions for HVM guests.
Changes in v3: * Remove unnecessary hypervisor code for clflushopt and clwb in patch 1. * Move the code refactoring in hvm_cpuid() to patch 2. * Replace checking host cpuid by checking VMX capabilities for pcommit. * Add a tag 'XEN' in the title to address Ian Campbell's comment in the corresponding QEMU patch series. Changes in v2: * Refactor modifications in hvm_cpuid() per Andrew Cooper's comments.
