Using a spinlock in the VLAN action causes performance issues when the VLAN
action is used on multiple cores. Rewrote the VLAN action to use RCU read

Hi all,
Here is a problem:
Here is a machine with several NUMA nodes and some of them are hot-pluggable,
It's not good for kernel to be extracted in the memory region of movable node.
But in current code, I print the address choosen by kaslr and found it may be
placed in movable node sometimes. To

The VLAN action maintains one set of stats across all cores, and uses a
spinlock to synchronize updates to it from the same. Changed this to use a
per-CPU stats context instead.

We currently returns the same error code (-EFAULT) to indicate two
different error cases:
1. a bug in vfio-ccw implementation has been found.
2. a buggy channel program has been detected.
This brings difficulty for userland program (specifically Qemu) to
handle.
Let's use -EFAULT to only indicate

If the count field of a ccw is zero, there is no need to
try to pin page(s) for it. Let's check the count value
before starting pinning operations.
