Subject: [PATCH 2/3] x86_64: use __PAGE_KERNEL* instead of _KERNPG_TABLE for 2MB PTEs in memory initialization
Date: Tue, 4 Dec 2007 16:23:50 +0100 [thread overview]
Message-ID: <1196781831199-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <11967818313616-git-send-email-joerg.roedel@amd.com>
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.
