Subject: [PATCH 4/3] syscalls/x86: adapt syscall_wrapper.h to the new syscall stub naming convention
Date: Sun, 8 Apr 2018 22:06:58 +0200	[thread overview]
Message-ID: <20180408200658.GA29848@light.dominikbrodowski.net> (raw)
In-Reply-To: <20180408195952.GA27462@light.dominikbrodowski.net>

Make the code in syscall_wrapper.h more readable by naming the stub macros
similar to the stub they provide. While at it, fix a stray newline at the
end of the __IA32_COMPAT_SYS_STUBx macro.
