Re: [PATCH v6 01/17] powerpc/vas: Define macros, register fields and structures

Define macros for the VAS hardware registers and bit-fields as well
as couple of data structures needed by the VAS driver.

Changelog[v6]
	- Add some fields for FTW windows

Changelog[v4]
	- [Michael Neuling] Move VAS code to arch/powerpc; Reorg vas.h and
	  vas-internal.h to kernel and uapi versions; rather than creating
	  separate properties for window context/address entries in device
	  tree, combine them into "reg" properties; drop ->hwirq and irq_port
	  fields from vas_window as they are only needed with user space
	  windows.
	- Drop the error check for CONFIG_PPC_4K_PAGES. Instead in a
	  follow-on patch add a "depends on CONFIG_PPC_64K_PAGES".

Changelog[v3]
	- Rename winctx->pid to winctx->pidr to reflect that its a value
	  from the PID register (SPRN_PID), not the linux process id.
	- Make it easier to split header into kernel/user parts
	- To keep user interface simple, use macros rather than enum for
	  the threshold-control modes.
	- Add a pid field to struct vas_window - needed for user space
	  send windows.

Changelog[v2]
	- Add an overview of VAS in vas-internal.h
	- Get window context parameters from device tree and drop
	  unnecessary macros.

I thought we weren't exposing VAS to userspace yet?

If we are then we need to get things straight WRT copy/paste abort.
