+Subject: [PATCH] selftests: timers: Fix clock_adjtime for newer 32-bit arches
+
+Newer 32-bit architectures e.g. riscv32 are using 64-bit time_t
+from get go, they have not wired __NR_clock_adjtime at all
+valid-adjtimex testcase fails to compile on such architectures.
+if this condition is found then use 64-bit adjtime syscall
