Remove spurious MSR_SE reset during kprobe processing.
single_step_exception() already does it for us. Reset it to be safe when
executing the fault_handler.

Add stricter checks during kprobe registration. Return correct error value so
insmod doesn't succeed. Also printk reason for registration failure.

Kprobes was eating the hardware instruction and data address
breakpoint exceptions. This patch fixes it; kprobes doesn't use those
exceptions at all and should ignore them.

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!
