+Subject: [PATCH] perf: Alias SYS_futex with SYS_futex_time64 on 32-bit arches
+ with 64bit time_t
+
+glibc does not define SYS_futex for 32bit architectures using 64bit
+time_t e.g. riscv32, therefore perf fails to compile as it does not find
+SYS_futex in C library headers, define it to SYS_futex_time64 when it
+exists
+
+Upstream-Status: Pending
