Subject: [PATCH] cpu_x86: Add x86ModelCopySignatures helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduce a helper for copying CPU signature between two CPU models.

It's not very useful until the way we store signatures is changed in the
next patch.
