The new Coherent Accelerator Interface Architecture, level 2, for the
IBM POWER9 brings new content and features:
- POWER9 Service Layer
- Registers
- Radix mode
- Process element entry
- Dedicated-Shared Process Programming Model
- Translation Fault Handling
- CAPP
- Memory Context ID
If a valid mm_struct is found the memory context id is used for each
transaction associated with the process handle. The PSL uses the
context ID to find the corresponding process element.

I'm ok with the code. However checkpatch is complaining about a
tab/space error in native.c
I already fixed it up when I applied them (and a bunch of other things).
If you have a quick respin, I also have a comment below about the
documentation.
So please send me an incremental patch to update the doco and I'll
squash it before merging the series.
cheers
Hi,
Here is a new patch which updates the documentation based
on the complet PATCH V4 7/7.
Let me know if it suits you.
Thanks
