svn commit: r230632 - in head/sys/sparc64: include sparc64

[Marius Strobl]

Author: marius
Date: Fri Jan 27 22:35:53 2012
New Revision: 230632
URL: http://svn.freebsd.org/changeset/base/230632

Log:
  - Now that we have a working OF_printf() since r230631, use it for
    implementing a simple OF_panic() that may be used during the early
    cycles when panic() isn't available, yet.
  - Mark cpu_{exit,shutdown}() as __dead2 as appropriate.
