[Xen-devel] [PATCH 1/2] x86/32: no need to use set_pte_present in set_pte_vaddr



From: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>

Impact: cleanup, remove last user of set_pte_present

set_pte_vaddr() is only used to install ptes in fixmaps, and
should never be used to overwrite a present mapping.
