Subject: [PATCH 0/3] [PULL REQUEST] iommu/vt-d: Fixes for v6.15-rc1

Hi Joerg,

The following fixes have been queued for the Intel iommu driver. They
aim to solve the following issues:

- Fix a lockdep warning of possible circular locking dependency
- Prevent disabled posted MSIs when IRTE reverts from vCPU to host

These fixes are non-critical for v6.14-rc. Considering the upcoming
merge window, it would be fine to include them with other patches for
v6.15.

Can you please take them?

Best regards,
baolu
