Sorry - i thought for a moment that it was introduced by this recent
change:
7f8b7ed: kgdb: Always process the whole breakpoint list on activate or deactivate
but it's deeper than that indeed.
Basically we have two options:
A- change kgdb to use the hw-breakpoints highlevel APIs (i'd prefer
that)
B- or keep what we had so far: kgdb overrides existing GDB (and now
perf) breakpoints
I havent noticed that hw-breakpoints lock up under kgdb.
