        src/sys/arch/mips/conf [matt-nb5-mips64]: kern.ldscript
        src/sys/arch/mips/include [matt-nb5-mips64]: locore.h
        src/sys/arch/mips/mips [matt-nb5-mips64]: locore.S mips_fixup.c
            mips_machdep.c spl_stubs.c

Log Message:
Rework how fixups are processed.  Inside of generating a table, we just
scan kernel text for jumps to locations between (__stub_start, __stub_end]
and if found, we actually decode the instructions in the stub to find out
where the stub would eventually jump to and then patch the original jump
to jump directly to it bypassing the stub.  This is slightly slower than
the previous method but it's a simplier and new stubs get automagically
handled.
