[gregkh]

The patch below does not apply to the 6.3-stable tree.
If someone wants it applied there, or to any other stable or longterm
tree, then please email the backport, including the original git commit
id to <stable@vger.kernel.org>.

To reproduce the conflict and resubmit, you may use the following commands:

git fetch https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/ linux-6.3.y
git checkout FETCH_HEAD
git cherry-pick -x 11c439a19466e7feaccdbce148a75372fddaf4e9

Subject: [PATCH] iommu/amd/pgtbl_v2: Fix domain max address

IOMMU v2 page table supports 4 level (47 bit) or 5 level (56 bit) virtual
address space. Current code assumes it can support 64bit IOVA address
space. If IOVA allocator allocates virtual address > 47/56 bit (depending
on page table level) then it will do wrong mapping and cause invalid
translation.

Hence adjust aperture size to use max address supported by the page table.

I'm not sure what happened, but it works for me:

# git fetch https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/ linux-6.3.y
From https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux
 * branch                      linux-6.3.y -> FETCH_HEAD
Auto packing the repository in background for optimum performance.
See "git help gc" for manual housekeeping.
# git co FETCH_HEAD
Note: switching to 'FETCH_HEAD'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

You are right. This applies cleanly on 6.3 stable branch. But it won't build. We
have dependency on below commit:

f594496403fa ("iommu/amd: Add 5 level guest page table support")

Sigh, nope skipped right over that. I even sent a reply when the original patch was sent saying it would need
to be changed for stable:

    For the stable releases, this will need to be PAGE_MODE_4_LEVEL
    instead of amd_iommu_gpt_level? The 6.4 merge window is when
    amd_iommu_gpt_level arrived with the 5 level page table changes.

Sorry for the noise.

[PATCH 6.3.y] iommu/amd/pgtbl_v2: Fix domain max address

[Vasant Hegde]

[ Upstream commit 11c439a19466e7feaccdbce148a75372fddaf4e9 ]

IOMMU v2 page table supports 4 level (47 bit) or 5 level (56 bit) virtual
address space. Current code assumes it can support 64bit IOVA address
space. If IOVA allocator allocates virtual address > 47/56 bit (depending
on page table level) then it will do wrong mapping and cause invalid
translation.

Hence adjust aperture size to use max address supported by the page table.
