Subject: [PATCH 0/3] Fix some build warnings in perf/events subsystem.

I have got these warnings when building kernel with  'W=1' options:

kernel/events/core.c:6670:6: warning: no previous prototype for 'perf_pmu_snapshot_aux' [-Wmissing-prototypes]
kernel/events/core.c:143: warning: Function parameter or member 'cpu' not described in 'cpu_function_call'
kernel/events/core.c:11924: warning: Function parameter or member 'flags' not described in 'sys_perf_event_open'
kernel/events/core.c:12382: warning: Function parameter or member 'overflow_handler' not described in 'perf_event_create_kernel_counter'
kernel/events/core.c:12382: warning: Function parameter or member 'context' not described in 'perf_event_create_kernel_counter'
kernel/events/hw_breakpoint.c:461: warning: Function parameter or member 'context' not described in 'register_user_hw_breakpoint'
kernel/events/hw_breakpoint.c:560: warning: Function parameter or member 'context' not described in 'register_wide_hw_breakpoint'

The 3-patch series will fix these warnings.

Haocheng Xie (3):
  perf core:  Make local function perf_pmu_snapshot_aux() static
  perf core: Fix some kernel-doc warnings.
  perf/hw_breakpoint: Fix kernel-doc warnings in perf hw_breakpoint
