The system physical address (SPA) of an error is not a stable value. It
will change depending on the location of the memory: parts can be
swapped. And it will change depending on memory topology: NUMA nodes
and/or interleaving can be adjusted.
Therefore, the SPA value is not part of the "FRU Memory Poison" record
format. And it will not be saved to persistent storage.
However, the SPA values can be helpful during debug and for system
admins during run time.
Save the SPA values in a separate structure. This is updated when
records are restored and when new errors are saved.
[ bp: Make error messages more user friendly and add and correct
comments. ]

The existing I/O page fault handler currently locates the PCI device by
calling pci_get_domain_bus_and_slot(). This function searches the list
of all PCI devices until the desired device is found. To improve lookup
efficiency, replace it with device_rbtree_find() to search the device
within the probed device rbtree.
The I/O page fault is initiated by the device, which does not have any
synchronization mechanism with the software to ensure that the device
stays in the probed device tree. Theoretically, a device could be released
by the IOMMU subsystem after device_rbtree_find() and before
iopf_get_dev_fault_param(), which would cause a use-after-free problem.
Add a mutex to synchronize the I/O page fault reporting path and the IOMMU
release device path. This lock doesn't introduce any performance overhead,
as the conflict between I/O page fault reporting and device releasing is
very rare.

Use a red-black tree(rbtree) to track devices probed by the driver's
probe_device callback. These devices need to be looked up quickly by
a source ID when the hardware reports a fault, either recoverable or
unrecoverable.
Fault reporting paths are critical. Searching a list in this scenario
is inefficient, with an algorithm complexity of O(n). An rbtree is a
self-balancing binary search tree, offering an average search time
complexity of O(log(n)). This significant performance improvement
makes rbtrees a better choice.
Furthermore, rbtrees are implemented on a per-iommu basis, eliminating
the need for global searches and further enhancing efficiency in
critical fault paths. The rbtree is protected by a spin lock with
interrupts disabled to ensure thread-safe access even within interrupt
contexts.

Commit 2f26e0a9c986 ("iommu/vt-d: Add basic SVM PASID support") added a
special treatment to mandate that no page faults may be outstanding for
the PASID after intel_svm_unbind_mm() is called, as the PASID will be
released and reused after unbind.
This is unnecessary anymore as no outstanding page faults have been
ensured in the driver's remove_dev_pasid path:
- Tear down the pasid entry, which guarantees that new page faults for
the PASID will be rejected by the iommu hardware.
- All outstanding page faults have been responded to.
- All hardware pending faults are drained in intel_drain_pasid_prq().
Remove this unnecessary code.

This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1].
Here the multiplication is obviously safe because DMAR_LATENCY_NUM
is the number of latency types defined in the "latency_type" enum.
enum latency_type {
DMAR_LATENCY_INV_IOTLB = 0,
DMAR_LATENCY_INV_DEVTLB,
DMAR_LATENCY_INV_IEC,
DMAR_LATENCY_PRQ,
DMAR_LATENCY_NUM
};
However, using kcalloc() is more appropriate [2] and improves
readability. This patch has no effect on runtime behavior.

Commit 62edf5dc4a524 ("intel-iommu: Restore DMAR_BROKEN_GFX_WA option for
broken graphics drivers") was introduced 24 years ago as a temporary
workaround for graphics drivers that used physical addresses for DMA and
avoided DMA APIs. This workaround was disabled by default.
As 24 years have passed, it is expected that graphics driver developers
have migrated their drivers to use kernel DMA APIs. Therefore, this
workaround is no longer required and could been removed.
The Intel iommu driver also provides a "igfx_off" option to turn off
the DMA translation for the graphic dedicated IOMMU. Hence, there is
really no good reason to keep this config option.

Forward skbs sent from one netdevsim port to its connected netdevsim
port using dev_forward_skb, in a spirit similar to veth.
Add a tx_dropped variable to struct netdevsim, tracking the number of
skbs that could not be forwarded using dev_forward_skb().
The xmit() function accessing the peer ptr is protected by an RCU read
critical section. The rcu_read_lock() is functionally redundant as since
v5.0 all softirqs are implicitly RCU read critical sections; but it is
useful for human readers.
If another CPU is concurrently in nsim_destroy(), then it will first set
the peer ptr to NULL. This does not affect any existing readers that
dereferenced a non-NULL peer. Then, in unregister_netdevice(), there is
a synchronize_rcu() before the netdev is actually unregistered and
freed. This ensures that any readers i.e. xmit() that got a non-NULL
peer will complete before the netdev is freed.
Any readers after the RCU_INIT_POINTER() but before synchronize_rcu()
will dereference NULL, making it safe.
The codepath to nsim_destroy() and nsim_create() takes both the newly
added nsim_dev_list_lock and rtnl_lock. This makes it safe with
concurrent calls to linking two netdevsims together.

Currently QCA808x driver does not fill the possible_interfaces.
2.5G QCA808x support SGMII and 2500Base-X while 1G model only supports
SGMII, so fill the possible_interfaces accordingly.

There are 2 versions of QCA808x, one 2.5G capable and one 1G capable.
Currently, this matter only in the .get_features call however, it will
be required for filling supported interface modes so lets add a helper
that can be reused.

It is now possible to disable BQL, but that causes the cpsw driver to break:
drivers/net/ethernet/ti/am65-cpsw-nuss.c:297:28: error: no member named 'dql' in 'struct netdev_queue'
297 | dql_avail(&netif_txq->dql),
There is already a helper function in net/sch_generic.h that could
be used to help here. Move its implementation into the common
linux/netdevice.h along with the other bql interfaces and change
both users over to the new interface.
