Subject: [PATCH 4.4 21/99] MIPS: Build microMIPS VDSO for microMIPS kernels
Date: Sun, 5 Jun 2016 14:40:54 -0700 [thread overview]
Message-ID: <20160605213905.040748412@linuxfoundation.org> (raw)
In-Reply-To: <20160605213902.974592018@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: James Hogan <james.hogan@imgtec.com>
commit bb93078e655be1e24d68f28f2756676e62c037ce upstream.
MicroMIPS kernels may be expected to run on microMIPS only cores which
don't support the normal MIPS instruction set, so be sure to pass the
-mmicromips flag through to the VDSO cflags.
Fixes: ebb5e78cc634 ("MIPS: Initial implementation of a VDSO")
