* MFC 305836: Remove 'cpu' and 'cpu_class' on amd64.jhb2016-11-081-0/+5
| | | | | | | | The 'cpu' and 'cpu_class' variables were always set to the same value on amd64 and are legacy holdovers from i386. Remove them entirely on amd64. Requested by: kib (MFC)
* Move shared variables from {amd64,i386}/initcpu.c to x86/identcpu.c.jhb2015-12-231-21/+2
| | | | | | | | While here, move the common bits of <machine/cputypes.h> to <x86/cputypes.h> as well. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D4670
