Subject: [PATCH] x86/sgx: Clean up internal includes
Date: Tue,  3 Sep 2019 21:16:35 +0300
Message-ID: <20190903181635.3937-1-jarkko.sakkinen@linux.intel.com> (raw)

Include arch.h from sgx.h and include sgx.h from other headers. Do not
include sgx.h from .c files. This makes a sane include order. Any new
header should only need to include sgx.h. The .c files must include the
modules they use.
