      MIPS: Loongson: Add support for perf tool · e2e13925
      Tiezhu Yang authored
      In order to use perf tool on the Loongson platform, we should enable kernel
      support for various performance events provided by software and hardware,
      so add CONFIG_PERF_EVENTS=y to loongson3_defconfig.
      
      E.g. without this patch:
      
      [loongson@localhost perf]$ ./perf list
      
      List of pre-defined events (to be used in -e):
      
        duration_time                                      [Tool event]
      
        rNNN                                               [Raw hardware event descriptor]
        cpu/t1=v1[,t2=v2,t3 ...]/modifier                  [Raw hardware event descriptor]
         (see 'man perf-list' on how to encode it)
      
        mem:<addr>[/len][:access]                          [Hardware breakpoint]

      MIPS: Rename the "Fill" cache ops to avoid build failure · a44f8309
      Huacai Chen authored
      MIPS define a "Fill" macro as a cache operation in cacheops.h, this
      will cause build failure under some special configurations because in
      seq_file.c there is a "Fill" label. To avoid this failure we rename the
      "Fill" macro to "Fill_I" which has the same coding style as other cache
      operations in cacheops.h (we think renaming the "Fill" macro is more
      reasonable than renaming the "Fill" label).
      
      Callers of "Fill" macro is also updated.
