From a8f90e906783f1f815120eefe813b23cb396e9bd Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Tue, 22 Sep 2009 09:48:08 +1000 Subject: perf_event, powerpc: Fix compilation after big perf_counter rename This fixes two places in the powerpc perf_event (perf_counter) code where 'list_entry' needs to be changed to 'group_entry', but were missed in commit 65abc865 ("perf_counter: Rename list_entry -> group_entry, counter_list -> group_list"). This also changes 'event' back to 'counter' in a couple of contexts: * Field and function names that deal with the limited-function counters: it's really the hardware counters whose function is limited, not the events that they count. Hence: MAX_LIMITED_HWEVENTS -> MAX_LIMITED_HWCOUNTERS limited_event -> limited_counter freeze/thaw_limited_events -> freeze/thaw_limited_counters * The machine-specific PMU description struct (struct power_pmu): this renames 'n_event' back to 'n_counter' since it really describes how many hardware counters the machine has. (Renaming this back avoids a compile error in each of the machine-specific PMU back-ends where they initialize their power_pmu struct.)
