Subject: [34-longterm 130/260] oprofile: Add Support for Intel CPU Family 6 / Model 22 (Intel Celeron 540)

From: Patrick Simmons <linuxrocks123@...scape.net>

commit c33f543d320843e1732534c3931da4bbd18e6c14 upstream.

This patch adds CPU type detection for the Intel Celeron 540, which is
part of the Core 2 family according to Wikipedia; the family and ID pair
is absent from the Volume 3B table referenced in the source code
comments.  I have tested this patch on an Intel Celeron 540 machine
reporting itself as Family 6 Model 22, and OProfile runs on the machine
without issue.
