Mostly, a kmalloc_node(GFP_NOFS) is appropriate, though occasionally

This patch introduces 4 alternatives to LIBCFS_CPT_ALLOC():
kmalloc_cpt()
kzalloc_cpt()
kvmalloc_cpt()
kvzalloc_cpt().
Each takes a size, gfp flags, and cpt number.
Almost every call to LIBCFS_CPT_ALLOC() passes lnet_cpt_table()
as the table. This patch embeds that choice in the k*alloc_cpt()
macros, and opencode kzalloc_node(..., cfs_cpt_spread_node(..))

staging: fsl-dpaa2/eth: Use affine DPIO services
Use the newly added DPIO service API to map cpu-affine DPIO services
to channels.
The DPAA2 Ethernet driver already had mappings of frame queues and
channels to cpus, but had no control over the DPIOs used. We can
now ensure full affinity of hotpath hardware resources to cores,
which improves performance and almost eliminates some resource
contentions (e.g. enqueue/dequeue busy counters should be close to
zero from now on).
Making the pull channel operation core affine brings the most
significant benefits. This ensures the same DPIO service will be
used for all dequeue commands issued for a certain frame queue,
which is in line with the way hardware is optimized.
Additionally, we also use affine DPIOs for the frame enqueue and
buffer release operations in order to avoid resource contention.
dpaa2_io_service_register() and dpaa2_io_service_rearm()
functions receive an affine DPIO as argument mostly for uniformity,
but this doesn't change the previous functionality.

staging: fsl-mc/dpio: Add dpaa2_io_service_select() API
All DPIO service API functions receive a dpaa2_io service pointer
as parameter (NULL meaning any service will do) which indicates
the hardware resource to be used to execute the specified command.
There isn't however any available API for obtaining such a service
reference that could be used further, effectively forcing the users
to always request a random service for DPIO operations.
(The DPIO driver holds internally an array mapping services to cpus,
and affine services can be indirectly requested by a couple of API
functions: dpaa2_io_service_register and dpaa2_io_service_rearm
use the cpu id provided by the user to select the corresponding
service)
This patch adds a function for selecting a DPIO service based on
the specified cpu id. If the user provides a "don't care" value
for the cpu, we revert to the default behavior and return the next
DPIO, taken in a round-robin fashion from a list of available
services.

Coccinelle suggested to use BUG_ON instead of if condition followed by BUG
but BUG_ON should be used in situations where integrity of the system is no
longer guaranteed. In this case, as suggested by Stefan Wahren, vchiq isn't
critical.
Since it is not critical, BUG_ON should be avoided.
