Subject: [Xen-devel] [PATCH v4 0/6] Use C inlines for uaccess
Date: Wed,  4 Dec 2019 18:20:52 -0500	[thread overview]
Message-ID: <20191204232058.2500117-1-pasha.tatashin@soleen.com> (raw)

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
