Subject: [PATCH v4 03/13] kbuild: Raise the minimum required binutils version to 2.21
Date: Wed, 16 Jan 2019 14:48:39 -0800	[thread overview]
Message-ID: <20190116224849.8617-4-chang.seok.bae@intel.com> (raw)
In-Reply-To: <20190116224849.8617-1-chang.seok.bae@intel.com>

It helps to use some new instructions directly in inline assembly.
