Subject: [PATCH 3/3] x86/syscalls: Don't sdjust CFLAGS for syscall tables
Date: Mon, 24 May 2021 14:17:07 -0400	[thread overview]
Message-ID: <20210524181707.132844-4-brgerst@gmail.com> (raw)
In-Reply-To: <20210524181707.132844-1-brgerst@gmail.com>

The syscall_*.c files only contain data (the syscall tables).  There
is no need to adjust CFLAGS for tracing and stack protector since they
contain no code.
