Subject: x86_64: Set K8 CPUID flag for K8/Fam10h/Fam11h
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0bd8acd1a7fbb5492c1de8af271b6964a7fd5274;p=linux-beck.git

x86_64: Set K8 CPUID flag for K8/Fam10h/Fam11h

Previously this flag was only used on 32bit, but some shared code can use
it now.
