It took me a while to understand this code enough to be confident this
is the right solution. Note that CONFIG_HAVE_MIXED_BREAKPOINTS_REGS is
purely dependent on the architecture and could be replaced with something
that checks for x86||sh but it should be safe to assume that the
enum should never have been part of the uapi header.
