Subject: [PATCH v2 0/3] Use C inlines for uaccess

Changelog
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 changes.

Pavel Tatashin (3):
  arm/arm64/xen: use C inlines for privcmd_call
  arm64: remove uaccess_ttbr0 asm macros from cache functions
  arm64: remove the rest of asm-uaccess.h
