[PATCH 2/3] x86_64: use __PAGE_KERNEL* instead of _KERNPG_TABLEfor 2MB PTEs in memory initialization

From: Joerg Roedel
Date: Sun Dec 02 2007 - 08:22:42 EST


This minor cleanup replaces _KERNPG_TABLE with the __PAGE_KERNEL* for 2MB PTEs
in the x86_64 memory initialization code. The __PAGE_KERNEL* defines are more
appropriate for PTEs.
