These patches create a top-level function, called at IOMMU
initialization, to create a debugfs directory for the IOMMU. Under
this directory drivers may create and populate-specific directories
for their device internals.
Patch 1: general IOMMU enablement
Patch 2: basic AMD enablement to demonstra
Provide base enablement for using debugfs to expose internal data of an
IOMMU driver. When called, create the /sys/kernel/debug/iommu directory.
Emit a strong warning at boot time to indicate that this feature is
enabled.
This function is called from iommu_init, and creates the initial DebugFS

On a call to mmap an mmap provider (like an FS) can put
this flag on vma->vm_flags.
The VM_LOCAL_CPU flag tells the Kernel that the vma will be used
from a single-core only, and therefore invalidation (flush_tlb) of
PTE(s) need not be a wide CPU scheduling.
The motivation of this flag is the ZUF
