Subject[PATCH 0/6] hw_breakpoint: Let the user choose not to build it (and perf too)
Date
Hi,

Until now, x86 and superh32 had to always build hw_breakpoint and perf.
And powerpc and arm were always building hw_breakpoints when perf
was enabled.

After this patchset, one can simply disable hw_breakpoints if he
selected CONFIG_EXPERT. Afterward the user is free to select perf
or not. Except on SH unfortunately because that would require a
bit of change in ptrace to support singlestep failures.

Frederic Weisbecker (6):
hw_breakpoints: Split hardware breakpoints config
hw_breakpoints: Migrate breakpoint conditional build under new config
x86: Allow the user not to build hw_breakpoints
hw_breakpoints: Breakpoints arch ability don't need perf events
hw_breakpoints: Only force perf events if breakpoints are selected
hw_breakpoints: Drop remaining misplaced dependency on perf
