[PATCHv2 0/4] New Ion ioctls

From: Laura Abbott

Hi,

This is a follow up to my previous series[1] for Ion ioctls. I've changed the
focus slightly based on the feedback. The ID remapping was less useful than I
originally thought and without that addition there isn't much benefit to have
a new alloc ioctl. The ABI check and query interface still seem beneficial.
There was some discussion on where exactly these types of ioctls would be
called. I expect the answer will depend on exactly how it's integrated.

Long term, I'd still like to fix the ABI to not be a checklist of botching
up ioctls but that focus will come later.

Changes from v1:
- Rebased
- Dropped RFC
- Dropped ID remapping and dependent logic
- Changed query logic to only need one ioctl
- Fixed alignment of query ioctl structure
