This is the fourth (and hopefully last) version of the patch-set to add the
new subsystem for compute accelerators. I removed the RFC headline as
I believe it is now ready for merging.

Compare to v3, this patch-set contains one additional patch that adds
documentation regarding the accel subsystem. I hope it's good enough for
this stage. In addition, there were few very minor fixes according to
comments received on v3.

The patches are in the following repo:
https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/accel.git/log/?h=accel_v4

As in v3, The HEAD of that branch is a commit adding a dummy driver that
registers an accel device using the new framework. This can be served
as a simple reference.

v1 cover letter:

v2 cover letter:

v3 cover letter:

Thanks,
Oded.
