[XEN,v2,10/15] x86/domain: clean up superfluous #idef-s

Message ID 67d6604e8f66468c02f0c2e60315fc9251b69beb.1715761386.git.Sergiy_Kibrik@epam.com (mailing list archive)

Series x86: make cpu virtualization support configurable | expand

Commit Message

Remove preprocessor checks for CONFIG_HVM option, because expressions covered
by these checks are already guarded by cpu_has_svm, which itself depends
on CONFIG_HVM option (via CONFIG_SVM).

No functional change intended.
