sparc64: Make corrupted user stacks more debuggable.
Right now if we get a corrupted user stack frame we do a
do_exit(SIGILL) which is not helpful.
If under a debugger, this behavior causes the inferior process to
exit. So the register and other state cannot be examined at the time
of the event.
Instead, conditionally log a rate limited kernel log message and then
force a SIGSEGV.
With bits and ideas borrowed (as usual) from powerpc.
