Subject: [PATCH 5/11] hugetlb: add generic definition of NUMA_NO_NODE
Date: Tue, 15 Sep 2009 16:44:52 -0400 [thread overview]
Message-ID: <20090915204452.4828.83793.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20090915204327.4828.4349.sendpatchset@localhost.localdomain>
[PATCH 5/11] - hugetlb: promote NUMA_NO_NODE to generic constant
Against: 2.6.31-mmotm-090914-0157
New in V7 of series
Move definition of NUMA_NO_NODE from ia64 and x86_64 arch specific
headers to generic header 'linux/numa.h' for use in generic code.
NUMA_NO_NODE replaces bare '-1' where it's used in this series to
indicate "no node id specified". Ultimately, it can be used
to replace the -1 elsewhere where it is used similarly.
