Subject: [PATCH 3/4] Move bp_type_idx to include/linux/hw_breakpoint.h

From: Palmer Dabbelt <palmer@...belt.com>

This has a "#ifdef CONFIG_*" that used to be exposed to userspace.

The names in here are so generic that I don't think it's a good idea
to expose them to userspace (or even the rest of the kernel).  There are
multiple in-kernel users, so it's been moved to a kernel header file.
