Subject: [27/90] x86: Add new Intel CPU cache size descriptors

2.6.31-stable review patch.  If anyone has any objections, please let us know.

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

From: Dave Jones <davej@...hat.com>

commit 85160b92fbd35321104819283c91bfed2b553e3c upstream.

The latest rev of Intel doc AP-485 details new cache descriptors
that we don't yet support. 12MB, 18MB and 24MB 24-way assoc L3
caches.
