Subject: x86, centaur: Enable cx8 for VIA Eden too
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftip%2Ftip.git;a=commitdiff_plain;h=cb3f718de8301a969f8169d7d4160e73baff0b86

x86, centaur: Enable cx8 for VIA Eden too

My box with following cpuinfo needs the cx8 enabling still:

vendor_id	: CentaurHauls
cpu family	: 6
model		: 13
model name	: VIA Eden Processor 1200MHz
stepping	: 0
cpu MHz		: 1199.940
cache size	: 128 KB

This fixes valgrind to work on my box (it requires and checks
cx8 from cpuinfo).
