In check_preempt_equal_dl(), cpudl_find() is called with a NULL
later_mask, thus cpudl_find() here doesn't check cpudl::free_cpus

This patch takles this issue by always passing a non-NULL later_mask
to cpudl_find(), thereby fixing

The lis302 has already a DT binding described in [0],

This adds support for the N900's accelerometer to

It also adds a note, that the axis values may be

Since the 2 fucntions can safely run in vmbus_connection.work_queue without
hang, we don't need to schedule new work items into the per-channel workqueue.
Actally we can even remove the per-channel workqueue now -- we'll do it
