There is a seqcounter that protects against spurious allocation failures
when a task is changing the allowed nodes in a cpuset. There is no need
to check the seqcounter until a cpuset exists.

Better would be to preserve any existing settings:
AXD is Audio Processing IP by Imagination Technologies that can
decode multiple file formats and play them back.
We use alsa compress offload API to represent our audio driver.
This patch adds defs and initialisation files.

Add implementation of alsa compress offload operations.
At the moment we only support playback only.
