Merge tag 'drm-amdkfd-next-2015-06-03' of git://people.freedesktop.org/~gabbayo/linux into drm-next

drm-amdkfd-next-2015-06-03:

- Add the H/W debugger support module, including new IOCTLs to:
  - register/unregister a process as a debugged process
  - Set address watch-point in the debugged process's GPU kernel
  - Do a wave control operation in the debugged process's waves
  See the commit messages for more details on the available operations.

  The debugged process can only perform debug operation on itself. It is
  blocked by the amdkfd+H/W from performing operations on other processes's
  waves or GPU kernels. The blocking is done by setting the VMID and PASID of
  the debugged process in the packets that are sent to the CP with the debug
  instructions.

- Add support for static user-mode queues. These queues are regular queues,
  but because they belong to the debugged process, we need to make sure the CP
  doesn't preempt them during a debug operation. Therefore, we mark them as
  static for the CP ignore them during preemption.

- Support killing all the waves when a process is terminated. This is needed
  in case a process is terminated but we can't UNMAP its queues (can occur due
  to several reasons). In that case, the CP could be stuck unless we kill all
  its waves. This function is *very* important as it provides the kernel a high
  level of control over the GPU. The reason we didn't upstream this function
  so far, is because it is implemented using the H/W debugger module functions,
  so we had to wait until we can upstream the H/W debugger module.

- Replace declaration of bitmap from unsigned long to standard DECLARE_BITMAP
