      x86: Fix jump label with RO/NX module protection crash · 89696913
      由 matthieu castet 提交于 
      If we use jump table in module init, there are marked
as removed in __jump_table section after init is done.

But we already applied ro permissions on the module, so
we can't modify a read only section (crash in
remove_jump_label_module_init).

Make the __jump_table section rw.

      perf tools: Fix time function double declaration with glibc · 00e99a49
      由 Thomas Renninger 提交于 
      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
      由 Arnaldo Carvalho de Melo 提交于 
      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
      由 Arnaldo Carvalho de Melo 提交于 
      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
      由 Arnaldo Carvalho de Melo 提交于 
      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.
