[PATCH 10 of 31] x86: rename paravirt_alloc_pt etc after thepagetable structure
From: Jeremy Fitzhardinge
Date: Tue Mar 18 2008 - 01:32:32 EST
Rename (alloc|release)_(pt|pd) to pte/pmd to explicitly match the name
of the appropriate pagetable level structure.
Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@xxxxxxxxxx>
