Subject: [ 110/128] x86/Sandy Bridge: mark arrays in __init functions as __initconst

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "H. Peter Anvin" <hpa@...ux.intel.com>

commit ab3cd8670e0b3fcde7f029e1503ed3c5138e9571 upstream.

Mark static arrays as __initconst so they get removed when the init
sections are flushed.
