      perf tools: Fix time function double declaration with glibc · 00e99a49
      Thomas Renninger authored
      It's enough to include the local "debug.h" file to trigger it.
      
      man time reveals this is already declared in glibc:
      
      time - get time in seconds
      -> rename the variable.

      perf tools: Fix build by checking if extra warnings are supported · 065bef5a
      Arnaldo Carvalho de Melo authored
      The -Wstack-protector and -Wvolatile-register-var warnings, for
      instance, are not supported by gcc 3.4.6.
      
      So fix by doing the same check we already do for -fstack-protector-all.
      
      With this and the other patches in this series, perf builds unmodified
      on, for instance, RHEL4.

      perf tools: Add missing header, fixes build · a860a608
      Arnaldo Carvalho de Melo authored
      We need the definiton for __always_inline in bitops.h to fix the build
      on distros where it isn't available or compiler.h doesn't get included
      indirectly.
      
      One of the fixes needed to build perf on RHEL4 systems, for instance.

      perf tools: Fix 64 bit integer format strings · 9486aa38
      Arnaldo Carvalho de Melo authored
      Using %L[uxd] has issues in some architectures, like on ppc64.  Fix it
      by making our 64 bit integers typedefs of stdint.h types and using
      PRI[ux]64 like, for instance, git does.
      
      Reported by Denis Kirjanov that provided a patch for one case, I went
      and changed all cases.

      Where we don't have CPU_ALLOC & friends. As the tools are being used in older
      distros where the only allowed change are to replace the kernel, like RHEL4 and
      5.

      x86, hotplug: Fix powersavings with offlined cores on AMD · 93789b32
      Borislav Petkov authored
      ea530692 made a CPU use monitor/mwait
      when offline. This is not the optimal choice for AMD wrt to powersavings
      and we'd prefer our cores to halt (i.e. enter C1) instead. For this, the
      same selection whether to use monitor/mwait has to be used as when we
      select the idle routine for the machine.
      
      With this patch, offlining cores 1-5 on a X6 machine allows core0 to
      boost again.
