Two small bug fixes for the code you pulled for 4.3:
- Used a SHIFT define instead of a MASK define to check if a bit is turned on
when destroying hqd. Luckily, this is in gfx7 interface file with amdgpu,
which was used only for bring-up purposes of amdgpu, so no real effect on
a running system
- Used a logical AND instead of a bitwise AND operator, when initializing
sdma virtual memory when using SDMA queues

This patch adds the gfx8 interface file between amdgpu and amdkfd. This
interface file is currently in use when running on a Carrizo-based
system.
The interface itself is represented by a pointer to struct
kfd_dev. The pointer is located inside amdgpu_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 allows us to avoid locking between
amdkfd and amdgpu.
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 amdgpu.

This patch adds an interface file between amdgpu and amdkfd. This
interface file is H/W agnostic, thus containing functions that
operate the same for any AMD APU/GPU H/W generation.
The functions in this interface mirror (some) of the functions in
radeon_kfd.c (the radeon<-->amdkfd interface file). The main functions
are:
- amdgpu_amdkfd_init - initialize the amdkfd module
- amdgpu_amdkfd_load_interface - load the H/W interface according to the
currently probed device
- amdgpu_amdkfd_device_probe - probe the device in amdkfd
- amdgpu_amdkfd_device_init - initialize the device in amdkfd
- amdgpu_amdkfd_interrupt - call the ISR of amdkfd
- amdgpu_amdkfd_suspend - suspend callback from amdgpu
- amdgpu_amdkfd_resume - resume callback from amdgpu
This patch also modifies the relevant amdgpu files, to use this new
interface.
