Hi,

That's v2 of Kristina's 52-bit PA series, posted here:

http://lkml.kernel.org/r/1513184845-8711-1-git-send-email-kristina.martsenko@arm.com

I addressed the comments raised on the list and I plan to push it into
-next soon.

Changes in v2:

- Folded patches 7 and 8 from the original series into 1
- Definitions for TCR_IPS_*
- Renamed some asm macros and functions
- __create_hyp_mappings() changed to avoid passing an extra arg
- More code comments
- Added Reviewed/Tested tags I've got so far

Thanks,

Catalin
