HMM: introduce heterogeneous memory management v4.
This patch only introduce core HMM functions for registering a new
mirror and stopping a mirror as well as HMM device registering and
unregistering.
The lifecycle of HMM object is handled differently then the one of
mmu_notifier because unlike mmu_notifier there can be concurrent
call from both mm code to HMM code and/or from device driver code
to HMM code. Moreover lifetime of HMM can be uncorrelated from the
lifetime of the process that is being mirror (GPU might take longer
time to cleanup).
Changed since v1:
- Updated comment of hmm_device_register().
Changed since v2:
- Expose struct hmm for easy access to mm struct.
- Simplify hmm_mirror_register() arguments.
- Removed the device name.
- Refcount the mirror struct internaly to HMM allowing to get
rid of the srcu and making the device driver callback error
handling simpler.
- Safe to call several time hmm_mirror_unregister().
- Rework the mmu_notifier unregistration and release callback.
Changed since v3:
- Rework hmm_mirror lifetime rules.
- Synchronize with mmu_notifier srcu before droping mirror last
reference in hmm_mirror_unregister()
- Use spinlock for device's mirror list.
- Export mirror ref/unref functions.
- English syntax fixes.
