Hi Dave,
I'm resending this pull request due to Christian's email on the ioctl patch-set.
Highlights:
- Complete overhaul to the main IOCTL function, kfd_ioctl(), according to drm_ioctl() example. This includes changing the IOCTL definitions, so it breaks compatibility with previous versions of the userspace. However, because the kernel was not officialy released yet, and this the first kernel that includes amdkfd, I assume I can still do that at this stage.
- A couple of bug fixes for the non-HWS path (used for bring-ups and debugging purposes only).
Our QA team run a test on -rc2 and didn't discover any regressions, so I don't expect an additionl pull request for 3.19 unless something unexpected will pop-up.
