[v2 0/2] test capability for remote task

[Jike Song]

Sometimes vfio iommu type1 needs to pin memory for a remote task other
than current, thereby needs to test the CAP_IPC_LOCK capability for
that task.

The proper routine for this purpose is has_capability(), but it is
not yet exported for modules. None of currently exported capability-
testing symbols allows a specified task. So here in this series
has_capability() is exported then used in the vfio iommu type1 driver.



v2: -> Add Serge's Acked-by to PATCH [1/2]
    -> Remove the change in vfio_pin_pages_remote, since it's now guaranteed the 'current' process


Hi Alex,

I kept EXPORT_SYMBOL other than EXPORT_SYMBOL_GPL, since I'm still
worry about changing the type of existing exports in 'capability.c'.
I'm new to open-source fearing of violating GPL :)
