| |
2.6.36-stable review patch. If anyone has any objections, please let us 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.
