Subject: perf trace: Add getrandom beautifier related defines for older systems
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a355a61e43484ac02553b34b5f84ee84ca765fd6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

perf trace: Add getrandom beautifier related defines for older systems

Were the detached tarball (make perf-tar-src-pkg) build was failing because
those definitions aren't available in the system headers.

On RHEL7, for instance:

  builtin-trace.c: In function ‘syscall_arg__scnprintf_getrandom_flags’:
  builtin-trace.c:1113:14: error: ‘GRND_RANDOM’ undeclared (first use in this function)
    P_FLAG(RANDOM);
                ^
  builtin-trace.c:1114:14: error: ‘GRND_NONBLOCK’ undeclared (first use in this function)
    P_FLAG(NONBLOCK);
              ^
