IB/mlx5: Implements disassociate_ucontext API

Browse source

Implements the IB core disassociate_ucontext API.
The driver detaches the HW resources for a given user context to
prevent a dependency between application termination and device
disconnect. This is done by managing the VMAs that were mapped
to the HW bars such as doorbell and blueflame. When need to detach,
remap them to an arbitrary kernel page returned by the zap API.
