[ Upstream commit 0afcf29bab35d3785204cd9bd51693b231ad7181 ]
Reducing this noise when cross building to the Android NDK:
util/header.c: In function 'perf_header__fprintf_info': util/header.c:2710:45: warning: pointer targets in passing argument 1 of 'ctime' differ in signedness [-Wpointer-sign] fprintf(fp, "# captured on : %s", ctime(&st.st_ctime)); ^ In file included from util/../perf.h:5:0, from util/evlist.h:11, from util/header.c:22: /opt/android-ndk-r15c/platforms/android-26/arch-arm/usr/include/time.h:81:14: note: expected 'const time_t *' but argument is of type 'long unsigned int *' extern char* ctime(const time_t*) __LIBC_ABI_PUBLIC__; ^
