[PATCH 4.20 202/352] perf tools: Cast off_t to s64 to avoid warning on bionic libc

From: Greg Kroah-Hartman
Date: Mon Feb 11 2019 - 11:02:09 EST

4.20-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:
