New Revision: 362841
URL: https://svnweb.freebsd.org/changeset/base/362841
Log:
Move ID reading signatures to a better header
The functions to read the common user and kernel ID registers should be
in cpu.h rather than undefined.h as they are related to CPU details and
used by undefined instruction handlers.
