  "message": "[PATCH] paravirt: optimize ptep establish for pae\n\nThe ptep_establish macro is only used on user-level PTEs, for P-\u003eP mapping\nchanges.  Since these always happen under protection of the pagetable lock,\nthe strong synchronization of a 64-bit cmpxchg is not needed, in fact, not\neven a lock prefix needs to be used.  We can simply instead clear the P-bit,\nfollowed by a normal set.  The write ordering is still important to avoid the\npossibility of the TLB snooping a partially written PTE and getting a bad\nmapping installed.\n\nSigned-off-by: Zachary Amsden \u003czach@vmware.com\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
