Subject: clean up address limit helpers v2
Date: Tue, 14 Jul 2020 12:54:59 +0200	[thread overview]
Message-ID: <20200714105505.935079-1-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.


Changes since v1:
 - drop to incorrect hunks
 - fix a commit log typo
