Subject: [PATCH v4 14/18] x86, syscalls: Rename 32-bit specific syscalls
Date: Fri, 13 Mar 2020 15:51:40 -0400 [thread overview]
Message-ID: <20200313195144.164260-15-brgerst@gmail.com> (raw)
In-Reply-To: <20200313195144.164260-1-brgerst@gmail.com>
Rename the syscalls that only exist for 32-bit from x86_* to ia32_* to make it
clear they are for 32-bit only. Also rename the functions to match the syscall
name.
Signed-off-by: Brian Gerst <brgerst@gmail.com>
