Subject: x86, amd: Move BSP code to cpu_dev helper
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8fa8b035085e7320c15875c1f6b03b290ca2dd66;p=linux-beck.git

x86, amd: Move BSP code to cpu_dev helper

Move code which is run once on the BSP during boot into the cpu_dev
helper.

[ hpa: removed bogus cpu_has -> static_cpu_has conversion ]
