Description Jarod Wilson 2011-01-11 16:34:51 UTC

Description of problem:
The upstream kernel includes new memory allocation helper functions, vzalloc and vzalloc_node, which as one might guess, do the equivalent of vmalloc + memset 0. Multiple driver backport efforts for RHEL6.1 will benefit from these helper functions being generically available in the RHEL6 kernel.

Backport is a straight-forward drop-in of upstream commit e1ca7788dec6773b1a2bce51b7141948f2b8bccf, which applies with only minor line offset differences.
