Subject: clean up address limit helpers
Date: Fri, 10 Jul 2020 15:57:00 +0200	[thread overview]
Message-ID: <20200710135706.537715-1-hch@lst.de> (raw)

Hi all,

in preparation for eventually phasing out direct use of set_fs(), this
series removes the segment_eq() arch helper that is only used to
implement or duplicate the uaccess_kernel() API, and then adds
descriptive helpers to force the kernel address limit.
