Subject: [PATCH 00/14] arm64: 4.17 backport of the SSBD mitigation patches
Date: Fri, 20 Jul 2018 10:47:08 +0100	[thread overview]
Message-ID: <20180720094722.702-1-marc.zyngier@arm.com> (raw)

This is the backport of the arm64 SSBD patches to 4.17. Not much to
say here, this is basically what went into 4.18.

4.14 and 4.9 to follow.

Thanks,

	M.
