Subject: hugetlb-add-pte_huge-macro.patch removed from -mm tree
Date: Mon, 05 Sep 2005 02:24:17 -0700 [thread overview]
Message-ID: <200509050925.j859PvWn000459@shell0.pdx.osdl.net> (raw)
The patch titled
hugetlb: add pte_huge() macro
has been removed from the -mm tree. Its filename is
hugetlb-add-pte_huge-macro.patch
Patches currently in -mm which might be from agl@us.ibm.com are
From: Adam Litke <agl@us.ibm.com>
This patch adds a macro pte_huge(pte) for i386/x86_64 which is needed by a
patch later in the series. Instead of repeating (_PAGE_PRESENT |
_PAGE_PSE), I've added __LARGE_PTE to i386 to match x86_64.
