commit fa2f4c39c48f975ae1b87247fa2f71673e2838ca Author: Jan Beulich <jbeulich@xxxxxxxx> AuthorDate: Tue Dec 21 10:38:18 2021 +0100 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Tue Dec 21 10:38:18 2021 +0100 x86/perfc: conditionalize HVM and shadow counters There's no point including them when the respective functionality isn't enabled in the build. Note that this covers only larger groups; more fine grained exclusion may want to be done later on.
