- Subject: [PATCH] Define SYS_futex on 32bit arches using 64-bit time_t
- Newer 32bit arches like RISCV32 and ARC are using 64bit time_t
- from get go unlike other 32bit architecture therefore aliasing __NR_futex to
- __NR_futex_time64 helps avoid the below errors
- tst_checkpoint.c:99:17: error: use of undeclared identifier 'SYS_futex'

- [ moved definitions to lapi/futex.h ]
