I guess socfpga's other boards may need this patch, but I have Arria10
board only.
So add a new function socfpga_a10_cpu_kill(), keep the old function
socfpga_cpu_kill() for other boards.
I also verified CPU_HOTPLUG after applying this patch, everything seems well.

If one 'drm_gem_handle_create()' fails, we leak somes handles and some
memory.
In order to fix it:
- move the 'free(bo_state)' at the end of the function in the error
handling path. This has the side effect to also try to free it if the
first 'kcalloc' fails. This is harmless.

Found with -Wduplicate-decl-specifier, a relatively new compiler flag in
GCC7, and Clang.
list_for_each_entry() eventually calls container_of(), which
marks the loop variable as const. The first argument to
list_for_each_entry() is a type, which should not already be marked const,
otherwise the l

Hi, Michal
If the subject is "improve the log message on oom disable handling" would be
more accurate to me.
The original subject sounds the patch will adjust the code path, while it
doesn't.

Applications that consume a batch of entries in one go
can benefit from ability to return some of them back
into the ring.
Add an API for that - assuming there's space. If there's no space
naturally can't do this and have to drop entries, but this implies ring
is full

We used to dequeue one skb during recvmsg() from skb_array, this could
be inefficient because of the bad cache utilization and spinlock
touching for each packet. This patch tries to batch them by calling
batch dequeuing helpers explicitly on the exported skb array and pass
the skb back through msg_

This series tries to implement rx batching for vhost-net. This is done
by batching the dequeuing from skb_array which was exported by
underlayer socket and pass the sbk back through msg_control to finish
userspace copying. This is also the requirement for more batching
implemention on rx path.
