    SubjectRe: [RFC] Fix 2.6.33 x86 regression to kgdb hw breakpoints - due to perf API changes

    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.
