[git pull] amdkfd next 4.15 (part 2)

[Oded Gabbay]

Hi Dave,

Second pull request for 4.15 merge window.

highlights include:

- Usermode Events
The current events code implemented some data structures (waitqueue, fifo)
that were already implemented in the kernel. The patches below addresses
this issue by replacing them with the standard kernel implementation.
In addition, they simplify allocation of events IDs and memory for the events.

The patches also increase the maximum number of events while maintaining
compatibility with the older userspace library.

- Remove radeon support
Because Kaveri is fully supported in amdgpu and because current and future
versions of userspace libraries will only support amdgpu, we removed radeon
support from kfd. Current users can move to amdgpu while using the same
userspace libraries.

- Various bug fixes and cleanups

Thanks,
Oded
