Subject: [PATCH V3 04/17] syscalls: compat: Fix the missing part for __SYSCALL_COMPAT
Date: Thu, 20 Jan 2022 15:38:57 +0800 [thread overview]
Message-ID: <20220120073911.99857-5-guoren@kernel.org> (raw)
From: Guo Ren <guoren@linux.alibaba.com>
Make "uapi asm unistd.h" could be used for architectures' COMPAT
mode. The __SYSCALL_COMPAT is first used in riscv.
