Subject[PATCH v4 0/6] Use C inlines for uaccess
Date
Changelog:

v4:
- Split the first patch into two as Julien Grall
- Also as Mark Rutland suggested removed alternatives
from __asm_flush_cache_user_range.
v3:
- Added Acked-by from Stefano Stabellini
- Addressed comments from Mark Rutland
v2:
- Addressed Russell King's concern by not adding
uaccess_* to ARM.
- Removed the accidental change to xtensa

Convert the remaining uaccess_* calls from ASM macros to C inlines.

These patches apply against linux-next. I boot tested ARM64, and
compile tested ARM change
