Subject: [PATCH V9 07/20] syscalls: compat: Fix the missing part for __SYSCALL_COMPAT
Date: Tue, 22 Mar 2022 22:39:50 +0800 [thread overview]
Message-ID: <20220322144003.2357128-8-guoren@kernel.org> (raw)
In-Reply-To: <20220322144003.2357128-1-guoren@kernel.org>
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.
