The cursor_set2 hook provides the cursor hotspot position within the
cursor image. When the hotspot position changes, we can adjust the cursor
position such that the hotspot doesn't move on the screen. This prevents
the cursor from appearing to intermittently jump around on the screen
when the position of the hotspot within the cursor image changes.

This patch adds the interface between the radeon driver and the amdkfd driver.
The interface implementation is contained in radeon_kfd.c and radeon_kfd.h.
The interface itself is represented by a pointer to struct
kfd_dev. The pointer is located inside radeon_device structure.
All the register accesses that amdkfd need are done using this interface. This
allows us to avoid direct register accesses in amdkfd proper, while also
avoiding locking between amdkfd and radeon.
The single exception is the doorbells that are used in both of the drivers.
However, because they are located in separate pci bar pages, the danger of
sharing registers between the drivers is minimal.
Having said that, we are planning to move the doorbells as well to radeon.
v3:
Add interface for sa manager init and fini. The init function will allocate a
buffer on system memory and pin it to the GART address space via the radeon sa
manager.
All mappings of buffers to GART address space are done via the radeon sa
manager. The interface of allocate memory will use the radeon sa manager to sub
allocate from the single buffer that was allocated during the init function.
Change lower_32/upper_32 calls to use linux macros
Add documentation for the interface
v4:
Change ptr field type in kgd_mem from uint32_t* to void* to match to type that
is returned by radeon_sa_bo_cpu_addr
v5:
Change format of mqd structure to work with latest KV firmware
Add support for AQL queues creation to enable working with open-source HSA
runtime.
Move generic kfd-->kgd interface and other generic kgd definitions to a generic
header file that will be used by AMD's radeon and amdgpu drivers

Implementing a lock for selecting and accessing shader engines and arrays.

radeon and amdkfd share the doorbell aperture.
radeon sets it up, takes the doorbells required for its own rings
and reports the setup to amdkfd.
radeon reserved doorbells are at the start of the doorbell aperture.

To support HSA on KV, we need to limit the number of vmids and pipes
that are available for radeon's use with KV.
This patch reserves VMIDs 8-15 for amdkfd (so radeon can only use VMIDs
0-7) and also makes radeon thinks that KV has only a single MEC with a single
pipe in it
v3: Use define for static vmid allocation in radeon

Merge tag 'v3.18-rc4' into drm-next
backmerge to get vmwgfx locking changes into next as the
conflict with per-plane locking.
Just a bit of OCD cleanup on headers - this function isn't the core
interface any more but just a helper for drivers who haven't yet
transitioned to universal planes. Put the declaration at the right
spot and sprinkle necessary #includes over all drivers.
Maybe this helps to encourage driver maintainers to do the switch.
v2: Fix #include ordering for tegra, reported by 0-day builder.
v3: Include required headers, reported by Thierry.
