Pull up following revision(s) (requested by hannken in ticket #1073):
        sys/arch/x86/x86/errata.c: revision 1.23
        sys/arch/x86/include/cpufunc.h: revision 1.19
Adapt prototypes and usage of rdmsr_locked() and wrmsr_locked() to
their implementation.  Both functions don't take the passcode as
argument.
As wrmsr_locked() no longer writes the passcode to the msr the
erratum 721 on my Opteron 2356 really gets patched and cc1 no longer
crashes with SIGSEGV.
