Subject: [RFC v4 11/24] RISC-V: define __NR_futex as __NR_futex_time64 for 32-bit
Date: Sat, 10 Aug 2019 01:04:00 -0000 [thread overview]
Message-ID: <e1ebc1f85efd9e75a333879033a445532c30555c.1565398513.git.alistair.francis@wdc.com> (raw)
In-Reply-To: <cover.1565398513.git.alistair.francis@wdc.com>
The futex syscall isn't avaliable on R32 so let's define it to
be futex_time64 instead.
