Merge tag 'amdkfd-fixes-2015-01-06' of git://people.freedesktop.org/~gabbayo/linux into drm-fixes
- 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).
* tag 'amdkfd-fixes-2015-01-06' of git://people.freedesktop.org/~gabbayo/linux:
drm/amdkfd: rewrite kfd_ioctl() according to drm_ioctl()
drm/amdkfd: reformat IOCTL definitions to drm-style
drm/amdkfd: Do copy_to/from_user in general kfd_ioctl()
drm/amdkfd: unmap VMID<-->PASID when relesing VMID (non-HWS)
drm/radeon: Assign VMID to PASID for IH in non-HWS mode
drm/radeon: do not leave queue acquired if timeout happens in kgd_hqd_destroy()
drm/amdkfd: Load mqd to hqd in non-HWS mode
drm/amd: Fixing typos in kfd<->kgd interface
