Hi Sean,

I tested your patch with the RC2 today but unfortunately the kernel 
doesn't link after compiling.

Error messages:

   LD      .tmp_vmlinux.kallsyms1
`.exit.text' referenced in section `__bug_table' of crypto/algboss.o: 
defined in discarded section `.exit.text' of crypto/algboss.o

make[1]: *** [scripts/Makefile.vmlinux:34: vmlinux] Error 1
make: *** [Makefile:1252: vmlinux] Error 2

Maybe it is not an issue because of the patch because the RC1 compilied 
and linked with the patch.

@Dave
Please test the RC1 with Sean's patch.
