Subject: [GIT PULL] VFIO updates for v6.0-rc1
Hi Linus,
There's a minor merge conflict between commit:
afe4e376ac5d ("vfio: Move IOMMU_CAP_CACHE_COHERENCY test to after we know we have a group")
added in v5.19-rc7 and commit:
3b498b665621 ("vfio: Use device_iommu_capable()")
as noted[1] by Stephen Rothwell, with a resolution provided in his next build.
There are also addition potential conflicts with kvm390[2] and s390[3]
trees, but I don't currently see pull requests on list for those yet.
Thanks!
Alex
