New Revision: 201396
URL: http://svn.freebsd.org/changeset/base/201396

Log:
  - Demapping unused kernel TLB slots has proven to work reliably so move
    the associated debugging under bootverbose.
  - Remove freebsd4_sigreturn(); given that FreeBSD 4 didn't supported
    sparc64 this only ever served as a transition aid prior to FreeBSD
    5.0 and is unused by default since COMPAT_FREEBSD4 was removed from
    GENERIC in r143072 nearly 5 years ago.
