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
‘hw_breakpoint_weight’ [-Wmissing-prototypes]
