[PATCH v4 0/6] s390x/vfio-ccw: Channel Path Handling [QEMU]

[Eric Farman <farman@linux.ibm.com>]

Here is a new pass at the channel-path handling code for vfio-ccw,
to take advantage of the corresponding kernel patches posted here:

https://lore.kernel.org/kvm/20200505122745.53208-1-farman@linux.ibm.com/

I have all the main comments from v3 addressed, though I have a
couple of additional patches that do some further cleanups
(like, a generic callback for stsch) that weren't baked enough
to include here. They're working fine, but need some cleanups
(e.g., fixups vs standalone patches) before they're ready for
submission. Just wanted to have the basic QEMU code to go with
the new KVM series.

Changes are listed in git notes for the individual patches.

v3: https://lore.kernel.org/qemu-devel/20200417023440.70514-1-farman@linux.ibm.com/
v2: https://lore.kernel.org/qemu-devel/20200206214509.16434-1-farman@linux.ibm.com/
