Hello,
This series add virtio gpu userptr support and add libhsakmt capset.
The userptr feature is used for let host access guest user space memory,
this feature is used for GPU compute use case, to enable ROCm/OpenCL native
context. It should be pointed out that we are not
From: Honglei Huang
Add interval tree to manage the userptrs to prevent repeat creation.
If the userptr exists, the ioctl will return the existing BO, and it's
offset with the create ioctl address.

Add implement for virtio gpu userptr. Current solution is pinning
all the user space memory. The UMD needs manage all the userptrs.

Add a new context named HSAKMT for compute use case.

in this series patches only HSAKMT context can use the userptr
feature. HSAKMT is a GPU compute library in HSA stack, like
the role libdrm in mesa stack.

Add mmu notifier, there are some benefits:
- UMD do not need manage the userptrs, just alloc and free user space
memory, with the MMU notifier userpters can be managed by kernel.
- Can achieve a performance improvement of 20%~30%. With the MMU notifier
UMD like OpenCL can
