Subject[PATCH] [24/139] bootmem: Add alloc_bootmem_align()
Date
2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Suresh Siddha <suresh.b.siddha@intel.com>

commit 53dde5f385bc56e312f78b7cb25ffaf8efd4735d upstream.

Add an alloc_bootmem_align() interface to allocate bootmem with
specified alignment. This is necessary to be able to allocate the
xsave area in a subsequent patch.
