Subject: [PATCH 0/7] Simplify and fix fetch()
Date: Sun, 11 Jul 2010 18:42:28 +0300 [thread overview]
Message-ID: <1278862955-6890-1-git-send-email-avi@redhat.com> (raw)
fetch() has become a monster, with a zillion continues, breaks, and gotos.
Simplify it before Xiao adds even more.
Also fix the gpte validation race.
Avi Kivity (7):
KVM: MMU: Add link_shadow_page() helper
KVM: MMU: Use __set_spte to link shadow pages
KVM: MMU: Add drop_spte_if_large() helper
KVM: MMU: Add validate_direct_spte() helper
KVM: MMU: Add validate_indirect_spte() helper
KVM: MMU: Simplify spte fetch() function
KVM: MMU: Validate all gptes during fetch, not just those used for
new pages
