Subject: [x86] correct cpu cache info for Tolapai
Message-id: 20080115210229.GA30759@samurai.boston.redhat.com
O-Subject: [RHEL5.2 PATCH] correct cpu cache info for Tolapai (bz 426172)
Bugzilla: 426172

This is a one-liner to report the correct CPU cache information for the Intel
Tolapai system-on-a-chip. We have a sample board here and I verified that
/proc/cpuinfo previously reported 64KB and now properly reports 256KB.

The chip is 32-bit only, so I tested on RHEL5.1 i386 + -68 kernel with and w/o
the patch.

Please ACK.
