Christoph Hellwig bfe00c5bbd syscalls: use uaccess_kernel in addr_limit_user_check
Patch series "clean up address limit helpers", v2.

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.

This patch (of 6):

Use the uaccess_kernel helper instead of duplicating it.

[hch@lst.de: arm: don't call addr_limit_user_check for nommu]
