This patch only renames macro, with no code logic impacted. Two purpose to rename macro: 1. Align some macro name in PageTables1G.asm and PageTables2M.asm, so that these two files can be easily combined later. 2. Some Macro names such as PDP are not accurate, since 4 level page entry also uses this macro. PAGE_NLE (no leaf entry) is better Cc: Eric Dong <eric.dong@intel.com> Reviewed-by: Ray Ni <ray.ni@intel.com> Cc: Rahul Kumar <rahul1.kumar@intel.com> Tested-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Cc: Debkumar De <debkumar.de@intel.com> Cc: Catharine West <catharine.west@intel.com> Signed-off-by: Zhiguang Liu <zhiguang.liu@intel.com>
