Prepare for 2 HWs that sharing pgtable in different power-domains.
When there are 2 M4U HWs, it may has problem in the flush_range in which
we get the pm_status via the m4u dev, BUT that function don't reflect the
real power-domain status of the HW since there may be other HW also use
that power-domain.
DAM allocation is often done while the allocating device is runtime
suspended. In such a case the iommu will also be suspended and partial
flushing of the tlb will not be executed.
Therefore, we add a tlb_flush_all in the pm_runtime_resume to make
sure the tlb is always clean.
In other case, the iommu's power should be active via device

100GbE Intel Wired LAN Driver Updates 2022-03-03
Jacob Keller says:
This series refactors the ice networking driver VF storage from a simple
static array to a hash table. It also introduces krefs and proper locking
and protection to prevent common use-after-free and concurrency issues.
There are two motivations for this work. First is to make the ice driver
more resilient by preventing a whole class of use-after-free bugs that can
occur around concurrent access to VF structures while removing VFs.
The second is to prepare the ice driver for future virtualization work to
support Scalable IOV, an alternative VF implementation compared to Single
Root IOV. The new VF implementation will allow for more dynamic VF creation
and removal, necessitating a more robust implementation for VF storage that
can't rely on the existing mechanisms to prevent concurrent access
violations.
The first few patches are cleanup and preparatory work needed to make the
conversion to the hash table safe. Following this preparatory work is a
patch to migrate the VF structures and variables to a new sub-structure for
code clarity. Next introduce new interface functions to abstract the VF
storage. Finally, the driver is actually converted to the hash table and
kref implementation.

For various reasons based on the allocator behaviour and typical
use-cases at the time, when the max32_alloc_size optimisation was
introduced it seemed reasonable to couple the reset of the tracked
size to the update of cached32_node upon freeing a relevant IOVA.
However, since subsequent optimisations focused on helping genuine
32-bit devices make best use of even more limited address spaces, it
is now a lot more likely for cached32_node to be anywhere in a "full"
32-bit address space, and as such more likely for space to become
available from IOVAs below that node being freed.
At this point, the short-cut in __cached_rbnode_delete_update() really
doesn't hold up any more, and we need to fix the logic to reliably
provide the expected behaviour. We still want cached32_node to only move
upwards, but we should reset the allocation size if *any* 32-bit space
has become available.

from the CPU queue when the next PTP packet arrives. So initialize "err"
