Subject: x86_64: Remove serialize_cpu() inline
X-Git-Tag: v3.12-rc1~25490^2~75
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e295f75410eb19d2a9733508f7f5c093767592cd;p=kernel%2Fkernel-generic.git

x86_64: Remove serialize_cpu() inline

- It was redundant with sync_core()
- It was unused
- It was broken: no input arguments to cpuid; could fault randomly
  depending on eax contents.

Now it's gone.
