[PATCH 06/32] acpi: kacpi*_wq don't need WQ_MEM_RECLAIM

[Tejun Heo]

ACPI workqueues aren't used during memory reclaming.  Use
alloc_workqueue() to create workqueues w/o rescuers.

If the purpose of the separation between kacpid_wq and kacpi_notify_wq
was to give notifications better response time, kacpi_notify_wq can be
dropped and kacpi_wq can be created with higher @max_active.

Only compile tested.  Please feel free to take it into the subsystem
tree or simply ack - I'll route it through the wq tree.

Thanks.

Feel free to add my 
Signed-off-by: Dave Jones <davej@redhat.com> 
to this.

I looked it over, and didn't see anything objectionable.

As the patch is going through wq tree, I added Acked-by instead of
Signed-off-by.

Thank you.
