asm-generic: optimize generic uaccess for 8-byte loads and stores
(2019-04-23 21:51:41 +0200)
----------------------------------------------------------------
asm-generic: kill <asm/segment.h> and improve nommu generic uaccess helpers
Christoph Hellwig writes:
This is a series doing two somewhat interwinded things. It improves
the asm-generic nommu uaccess helper to optionally be entirely generic
and not require any arch helpers for the actual uaccess. For the
generic uaccess.h to actually be generically useful I also had to kill
off the mess we made of <asm/segment.h>, which really shouldn't exist
on most architectures.

Christoph Hellwig (4):
asm-generic: don't include <asm/segment.h> from <asm/uaccess.h>
arch: mostly remove <asm/segment.h>
asm-generic: provide entirely generic nommu uaccess
asm-generic: optimize generic uaccess for 8-byte loads and stores
