[PATCH 20/58] kernel/events/hw_breakpoint.c: Make hw_breakpoint_weight static

[Josh Triplett]

Commit f93a20541134fa767e8dc4eb32e956d30b9f6b92, in April 2010, added
the ability for hardware breakpoints to have variable "weight" in
allocations, and added a __weak function hw_breakpoint_weight that
architectures could override to set the weight of a breakpoint.  No
architecture has ever done so.

For now, change the function from __weak to static.  If this
functionality continues to go unused, the abstraction should probably go
away entirely.

This also eliminates a warning:

kernel/events/hw_breakpoint.c:80:27: warning: no previous prototype for âhw_breakpoint_weightâ [-Wmissing-prototypes]
