Subject: [PATCH 4.19 171/313] perf tools: Cast off_t to s64 to avoid warning on bionic libc

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 866053bb644f754d1a93aaa9db9998fecf7a8978 ]

To avoid this warning:

    CC       /tmp/build/perf/util/s390-cpumsf.o
  util/s390-cpumsf.c: In function 's390_cpumsf_samples':
  util/s390-cpumsf.c:508:3: warning: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'off_t' [-Wformat=]
     pr_err("[%#08" PRIx64 "] Invalid AUX trailer entry TOD clock base\n",
     ^

Now the various Android cross toolchains used in the perf tools
container test builds are all clean and we can remove this:

  export EXTRA_MAKE_ARGS="WERROR=0"
