Merge tag 'vfio-v6.18-rc1' of https://github.com/awilliam/linux-vfio
Pull VFIO updates from Alex Williamson:
- Use fdinfo to expose the sysfs path of a device represented by a vfio
device file (Alex Mastro)
- Mark vfio-fsl-mc, vfio-amba, and the reset functions for
vfio-platform for removal as these are either orphaned or believed to
be unused (Alex Williamson)
- Add reviewers for vfio-platform to save it from also being marked for
removal (Mostafa Saleh, Pranjal Shrivastava)
- VFIO selftests, including basic sanity testing and minimal userspace
drivers for testing against real hardware. This is also expected to
provide integration with KVM selftests for KVM-VFIO interfaces (David
Matlack, Josh Hilke)
- Fix drivers/cdx and vfio/cdx to build without CONFIG_GENERIC_MSI_IRQ
(Nipun Gupta)
- Fix reference leak in hisi_acc (Miaoqian Lin)
- Use consistent return for unsupported device feature (Alex Mastro)
- Unwind using the correct memory free callback in vfio/pds (Zilin
Guan)
- Use IRQ_DISABLE_LAZY flag to improve handling of pre-PCI2.3 INTx and
resolve stalled interrupt on ppc64 (Timothy Pearson)
- Enable GB300 in nvgrace-gpu vfio-pci variant driver (Tushar Dave)
- Misc:
- Drop unnecessary ternary conversion in vfio/pci (Xichao Zhao)
- Grammatical fix in nvgrace-gpu (Morduan Zang)
- Update Shameer's email address (Shameer Kolothum)
- Fix document build warning (Alex Williamson)
