 Modified Files:
 	src/sys/arch/sh3/sh3: exception.c
 
 Log Message:
 For kernel mode address error, do not overwrite tf->tf_spc and tf->tf_r0
 *before* checking pcb->pbc_onfault != NULL.
 
 Should fix part of
 
 PR port-sh3/56382
 PR port-sh3/56401
 
 i.e., DDB will no longer wrongly indicate NULL as fault PC for kernel mode
 address error (and 0xe == EFAULT as r0).
 
 Yes, we have another bugs that cause panics described in the two PRs, but
 now we can examine them more easily :).
