Subject: [PATCH v2 vfio 0/6] vfio/pds: Clean-ups and multi-region support

This series contains various clean-ups, improvements, and support
for multiple dirty tracking regions. The majority of clean-up and
improvements are in preparation for the last patch in the series,
which adds support for multiple dirty tracking regions.

Changes:

v2:
- Make use of BITS_PER_BYTE #define
- Use C99 style for loops
- Fix subject line to use vfio/pds instead of pds-vfio-pci
- Separate out some calculation fixes into another patch
  so it can be backported to 6.6-stable
- Fix bounds check in pds_vfio_get_region()

v1:

  vfio/pds: Only use a single SGL for both seq and ack
  vfio/pds: Move and rename region specific info
  vfio/pds: Pass region info to relevant functions
  vfio/pds: Move seq/ack bitmaps into region struct
  vfio/pds: Add multi-region support
