Subject: x86/common.c: Make have_cpuid_p() a global function
X-Git-Tag: next-20130218~38^2~58^2~9
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d288e1cf8e62f3e4034f1f021f047009c4ac0b3c;p=karo-tx-linux.git

x86/common.c: Make have_cpuid_p() a global function

Remove static declaration in have_cpuid_p() to make it a global function. The
function will be called in early loading microcode.
