Subject: [PATCH] x86, vmware: Remove alloc_pmd_clone hook.
Date: Mon, 23 Aug 2010 17:05:57 -0700 [thread overview]
Message-ID: <1282608357.19396.36.camel@ank32.eng.vmware.com> (raw)
Patch on top of tip/x86/vmware
VMI was the only user of the alloc_pmd_clone hook, given that VMI
is now removed we can also remove this hook.
