The current logic updates the I/O page table mode for the domain
before calling the logic to free memory used for the page table.
This results in IOMMU page table memory leak, and can be observed
when launching VM w/ pass-through devices.
Fix by freeing the memory used for page table before updati

Spinning this out of my bus ops stuff (currently 30 patches and
counting...)
From: Adrian Huang
When enabling VMD and IOMMU scalable mode, the following kernel panic
call trace/kernel log is shown in Eagle Stream platform (Sapphire Rapids
CPU) during booting:
pci :59:00.5: Adding to iommu group 42
...
vmd :59:00.5: PCI host bridge to bus 1:80
pci 1:80:01.
Hi,
This follows commit cca084692394a ("drm/i915: Use per device iommu check")
to convert intel_iommu_gfx_mapped use in agp/intel to device_iommu_mapped().
With this changed, the export intel_iommu_gfx_mapped could be removed.
Best regards,
baolu

agp/intel: Use per device iommu c
The exported symbol intel_iommu_gfx_mapped is not used anywhere in the
tree. Remove it to avoid dead code.

The IOMMU subsystem has already provided an interface to query whether
the IOMMU hardware is enabled for a specific device. This changes the
check from Intel specific intel_iommu_gfx_mapped (globally exported by
the Intel IOMMU driver) to probing the presence of IOMMU on a specific
device using the
kernel/dma/map_benchmark.c and selftests/dma/dma_map_benchmark.c
have duplicate map_benchmark definitions, which tends to lead to
inconsistent changes to map_benchmark on both sides, extract a
common header file to avoid this problem.
