Hi, this series is based on Cédric Le Goater's vfio cleanup series:
https://github.com/legoater/qemu/commits/vfio-10.1
The series contains patches to vfio to prepare for the vfio-user
implementation. A previous version of these patches can be found at
https://lore.kernel.org/all/7dd34008-e0f1-4eed
Add a helper similar to vfio_device_get_region_info() and use it
everywhere.
Replace a couple of needless allocations with stack variables.
As a side-effect, this fixes a minor error reporting issue in the call
from vfio_msix_early_setup().

Split out parts of TYPE_VFIO_PCI into a base TYPE_VFIO_PCI_BASE. The
base type contains properties generic to all vfio-pci implementations
(although we have not yet introduced another subclass).
Note that currently there is no need for additional data for
TYPE_VFIO_PCI, so it shares the same C str
For vfio-user, device operations such as IRQ handling and region
read/writes are implemented in userspace over the control socket, not
ioctl() or read()/write() to the vfio kernel driver; add an ops vector
to generalize this, and implement vfio_device_io_ops_ioctl for
interacting with the kernel vf
Pass through the MemoryRegion to DMA operation handlers of vfio
containers. The vfio-user container will need this later.

Instead of requesting region information on demand with
VFIO_DEVICE_GET_REGION_INFO, maintain a cache: this will become
necessary for performance for vfio-user, where this call becomes a
message over the control socket, so is of higher overhead than the
traditional path.
We will also need it to ge
The vfio-user container will later need to hook into these callbacks;
set up vfio to use them, and optionally pass them through to the
container.

Various bits of code that call vfio device APIs should consistently use
the "return -errno" approach for passing errors back, rather than
presuming errno is (still) set correctly.
