Since IOMMU map entries store a reference to the domain in which they
reside, there is no need to pass the domain to iommu_gas_free_entry(),
iommu_gas_free_space(), and iommu_gas_free_region().
Push down the acquisition and release of the IOMMU domain lock into
iommu_gas_free_space() and iommu_gas_free_region().
Both of these changes allow for simplifications in the callers of the
functions without really complicating the functions themselves.
Moreover, the latter change eliminates the direct use of the IOMMU
domain lock from the x86-specific DMAR code.

If iommu_gas_match_one has to adjust for a boundary crossing, its
check against maxaddr includes 'offset' in its calculation, to ensure
that the allocated memory does not exceed the max address. However, if
there's no boundary crossing adjustment, then the maxaddr check
disregards 'offset'. Fix that.

Eliminate a possible case of use-after-free in an error handling path
after a mapping failure. Specifically, eliminate IOMMU_MAP_ENTRY_QI_NF
and instead perform the IOTLB invalidation synchronously. Otherwise,
when iommu_domain_unload_entry() is called and told not to free the
IOMMU map entry, the caller could free the entry before dmar_qi_task()

In the extremely unlikely case that the iommu_gas_map_region() call in
bus_dma_iommu_load_ident() failed, we would attempt to unmap the failed
entry twice, first in iommu_gas_map_region(), and a second time in the
caller. Once is enough, and twice is problematic because it leads to a
second RB_REMOVE call on the same tree node. Like it or not, RB_TREE
does not handle that possibility.

After the device reset, the LLQ configuration descriptor wasn't passed
to the hardware. On a 6-generation AWS instances (like C6gn), it is
required to pass the LLQ descriptor after the device reset, otherwise
the hardware will be missing the LLQ configuration resulting in
performance degradation.
This patch reconfigures the LLQ each time the ena_device_init() is
called. This means that the LLQ descriptor will be passed during the
initial configuration and after a reset.
The ena_map_llq_mem_bar() function call was moved before the
ena_device_init() call, to make sure that the mem bar is available.

During probe the driver created a temporary buffer to which the value of
DEVICE_DESC constant was printed. This buffer was then copied to the
device structure using device_set_desc_copy. Since the value of this
string is exactly the same for every device using the ENA driver, using
sprintf is unnecessary, and device_set_desc can be used instead.

Copying ENI metrics was done in callout context, this caused the driver
to panic when sample_interval was set to a value other than 0, as the
admin queue call which was executed could sleep while waiting on
a condition variable. Taskqueue, unlike callout, allows for sleeping, so
moving the function to a separate taskqueue fixes the problem.
ena_timer_service is still responsible for scheduling the taskqueue.
Stop draining the callout during ena_up/ena_down. This was done to
prevent a race between ena_up/down and ena_copy_eni_metrics admin queue
calls. Since ena_metrics_task is protected by ENA_LOCK there is no
possibility of a race between ena_up/down and ena_metrics_task.
Remove a comment about locking in ena_timer_service. With ENI metrics
in a separate task this comment became obsolete.
