Subject: [git pull] IOMMU Updates for Linux v5.19
Hi Linus,
Apologies for the late pull request, I know you prefer the main stuff in
the first week. Some vacation and a public holiday came in between here.
So here are the IOMMU updates for 5.19. Some patches are probably
arleady merged via the VFIO tree, namely everyting from the
vfio-notifier-fix topic branch.
Also, there will be a merge conflict in MAINTAINERS and
drivers/iommu/amd/iommu.c. The latter one is resolved by removing the
function in question, for the former I attached my resolution.
With that in mind:
The following changes since commit 42226c989789d8da4af1de0c31070c96726d990c:
Linux 5.18-rc7 (2022-05-15 18:08:58 -0700)
are available in the Git repository at:
