do_debug() and do_int3() return void.
This patch fixes the CONFIG_KPROBES variant of do_int3() to return void too
and adjusts entry.S accordingly.

This makes a trap on the 'iret' that returns us to user space
cause a nice clean SIGSEGV, instead of just a hard (and silent)
exit.
That way a debugger can actually try to see what happened, and
we also properly notify everybody who might be interested about
us being gone.
This loses the error code, but tells the debugger what happened
with ILL_BADSTK in the siginfo.
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
