clean up address limit helpers v2
From: Christoph Hellwig
Date: Tue Jul 14 2020 - 06:57:27 EST
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
