Before trace can be collected the PMU needs to get a handle
on the mmpap'ed memory that was granted. Since the collection
of traces can be done by sink buffers of various types,

This platform driver has a OF device ID table but the OF module

Hi,
These patches add the missing MODULE_DEVICE_TABLE() for OF to export
the information so modules have the correct aliases built-in and
autoloading works correctly.

Ah, _not_
This is friendlier to clients of the code, who are going to prepare
vcpu_data structs unconditionally, even if CONFIG_IRQ_REMAP is not
defined.
