# Commit 3bea00966eb6680410c89df764d075a8fbacc3cc # Date 2018-01-05 19:57:07 +0000 # Author Andrew Cooper <andrew.cooper3@citrix.com> # Committer Andrew Cooper <andrew.cooper3@citrix.com> x86/hvm: Rename update_guest_vendor() callback to cpuid_policy_changed() It will shortly be used for more than just changing the vendor.
