Subject: [PATCH 0/2] x86/hvm: Improvements to HAP superpage feature detection
Date: Tue, 22 Sep 2015 18:33:01 +0100 [thread overview]
Message-ID: <1442943183-3529-1-git-send-email-andrew.cooper3@citrix.com> (raw)
Two small patches which reduce the runtime overhead of detecting HAP
superpages by moving more initialisation into __init.
Noticed while reviewing "x86/p2m: use large pages for MMIO mappings".
Andrew Cooper (2):
x86/hvm: Refine hap_has_{2mb,1gb} checks
x86/hvm: Fold opt_hap_{2mb,1gb} into hap_capabilities
