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
