Subject: [GIT PULL] arm64: fixes for -rc7
Date: Fri, 8 Jul 2016 15:49:00 +0100	[thread overview]
Message-ID: <20160708144859.GC6493@arm.com> (raw)

Hi Linus,

A couple of late fixes here, but one that we've been sitting on for a
few weeks while the details were worked out. Specifically, we now
enforce USER_DS on taking exceptions whilst in the kernel, which avoids
leaking kernel data to userspace through things like perf. The other
patch is an update to a workaround for a hardware erratum on some Cavium
SoCs.

Please pull,

Will
