VMD child devices must use the VMD endpoint's ID as the requester. Because
of this, there needs to be a way to link the parent VMD endpoint's IOMMU
group and associated mappings to the VMD child devices such that attaching
and detaching child devices modify the endpoint's mappings, while
preventing early detaching on a singular device removal or unbinding.
The reassignment of individual VMD child devices devices to VMs is outside
the scope of VMD, but may be implemented in the future. For now it is best
to prevent any such attempts.
Prevent VMD child devices from returning an IOMMU, which prevents it from
exposing an iommu_group sysfs directory and allowing subsequent binding by
userspace-access drivers such as VFIO.

====================
net/sched: Improve getting objects by indexes
Using current TC code, it is very slow to insert a lot of rules.
In order to improve the rules update rate in TC,
we introduced the following two changes:
1) changed cls_flower to use IDR to manage the filters.
2) changed all act_xxx modules to use IDR instead of
a small hash table
But IDR has a limitation that it uses int. TC handle uses u32.
To make sure there is no regression, we add several new IDR APIs
to support unsigned long.

Typically, each TC filter has its own action. All the actions of the
same type are saved in its hash table. But the hash buckets are too
small that it degrades to a list. And the performance is greatly
affected. For example, it takes about 0m11.914s to insert 64K rules.
If we convert the hash table to IDR, it only takes about 0m1.500s.
The improvement is huge.
But please note that the test result is based on previous patch that
cls_flower uses IDR.

Currently, all filters with the same priority are linked in a doubly
linked list. Every filter should have a unique handle. To make the
handle unique, we need to iterate the list every time to see if the
handle exists or not when inserting a new filter. It is time-consuming.
For example, it takes about 5m3.169s to insert 64K rules.
This patch changes cls_flower to use IDR. With this patch, it
takes about 0m1.127s to insert 64K rules. The improvement is huge.
But please note that in this testing, all filters share the same action.
If every filter has a unique action, that is another bottleneck.
Follow-up patch in this patchset addresses that.

VMD hardware has to share its vectors among child devices in its PCI
domain so we should allocate as many as possible rather than just ones
that can be affinitized.
pci_alloc_irq_vectors_affinity() limits the number of affinitized IRQs to
the number of present CPUs (see irq_calc_affinity_vectors()). But we'd
prefer to have more vectors, even if they aren't distributed across the
CPUs, so use pci_alloc_irq_vectors() instead.

When the user unbinds the last device of a group from a vfio bus
driver, the devices within that group should be available for other
purposes. We currently have a race that makes this generally, but
not always true. The device can be unbound from the vfio bus driver,
but remaining IOMMU context of the group attached to the container
can result in errors as the next driver configures DMA for the device.
Wait for the group to be detached from the IOMMU backend before
allowing the bus driver remove callback to complete.

In vfio_iommu_group_get() we want to increase the reference

In noiommu case, the group does not exist and is allocated.
iommu_group_add_device() increases the group ref count. However we
then call iommu_group_put() which decrements it.
This leads to a "refcount_t: underflow WARN_ON".
Only decrement the ref count in case of iommu_group_add_device

By using drm_gem_flink/drm_gem_open on an object using the same fd, it
is possible for a client to create multiple handles pointing to the same
object (tied to the same contexts and VMA), as exemplified by
igt::gem_handle_to_libdrm_bo(). Since this duplication has been possible
since forever, we cannot assume that the handle:(fpriv, object) is
unique and so must handle the multiple users of a single VMA.

Since we hold the device wakeref when writing through the GTT (otherwise
the writes would fail), we presumed that before the device sleeps those
writes would naturally be flushed and that we wouldn't need our mmio
read trick. However, that presumption seems false and a sleepy bxt seems
to require us to always manually flush the GTT writes prior to direct
access.

Sometimes we know we are the only user of the bo, but since we take a
protective pin_pages early on, an attempt to change the vmap on the
object is denied because it is busy. i915_gem_object_pin_map() cannot
tell from our single pin_count if the operation is safe. Instead we must
pass that information down from the caller in the manner of
I915_MAP_OVERRIDE.
This issue has existed from the introduction of the mapping, but was
never noticed as the only place where this conflict might happen is for
cached kernel buffers (such as allocated by i915_gem_batch_pool_get()).
Until recently there was only a single user (the cmdparser) so no
conflicts ever occurred. However, we now use it to allocate batches for
different operations (using MAP_WC on !llc for writes) in addition to the
existing shadow batch (using MAP_WB for reads).
We could either keep both mappings cached, or use a different write
mechanism if we detect a MAP_WB already exists (i.e. clflush
afterwards), but as we haven't seen this issue in the wild (it requires
hitting the GPU reloc path in addition to the cmdparser) for simplicity
just allow the mappings to be recreated.
v2: Include the i915_MAP_OVERRIDE bit in the enum so the compiler knows
about all the valid values.

Currently we're taking power_lock at each card component for assuring
the power-up sequence, but it doesn't help anything in the
implementation at the moment: it just serializes unnecessarily the
callers, but it doesn't protect about the power state change itself.
It used to have some usefulness in the early days where we managed the
PM manually. But now the suspend/resume core procedure is beyond our
hands, and power_lock lost its meaning.
This patch drops the power_lock from allover the places.
There shouldn't be any issues by this change, as it's no helper
regarding the power state change. Rather we'll get better performance
by removing the serialization; which is the only slight concern of any
behavior change, but it can't be a showstopper, after all.

net: Add support for rmnet driver
This patch series adds support for the rmnet driver which is required to
support recent chipsets using Qualcomm Technologies, Inc. modems. The data
from hardware follows the multiplexing and aggregation protocol (MAP).
This driver can be used to register onto any physical network device in
IP mode. Physical transports include USB, HSIC, PCIe and IP accelerator.
rmnet driver helps to decode these packets and queue them to network
stack (and encode and transmit it to the physical device).
v1: Same as the RFC patch with some minor fixes for issues reported by
kbuild test robot.
v1->v2: Change datatypes and remove config IOCTL as mentioned by David.
Also fix checkpatch issues and remove some unused code.
v2->v3: Move location to drivers/net and rename to rmnet. Change the
userspace - netlink communication from custom netlink to rtnl_link_ops.
Refactor some code. Use a fixed config for ingress and egress.
v3->v4: Move location to drivers/net/ethernet/qualcomm/.
Fix comments from Stephen and Jiri -
Split the ether and arp type changes into seperate patches.
Remove debug and custom logging and switch to standard netdevice log.
Remove module parameters. Refactor and change some code style issues.
v4->v5: Rename some structs and variables. Move the initializer
before the for loop start. Put the arp type in correct sequence.
v5->v6: Fix comments from Dan -
Use the upper link API. As a result, remove all the refcounting logic.
Device refcount is explicitly held on real_dev on rx_handler
registration only. Modifiy the flow control struct. Remove the unused
ethernet mode handling.
v6->v7: Fix comments from David - Add newline to end of Makefile. Remove
inline from .c files. Move the module init/exit to rmnet config. Fix an
error reported by kbuild test robot for an unused file.
v7->v8: Use a smaller value for ETH_P_MAP as mentioned by David. Change
netdev_info to netdev_dbg as mentioned by Andew. Fix comments from
Stephen regarding netdev_priv and sparse related errors of using 0 as NULL
v8->v9: Fix comments from David - Remove the CFLAG rule. Change the way
rmnet devices are freed. Instead of using a workqueue to unregister devices
individually, go through the list and free all devices within the rtnl_lock().
v9->v10: Actually fix the locking as mentioned by David. The locking scheme is
mentioned in a comment in rmnet_config.c. Change comment near MAP type
definition as mentioned by Dan. Refactor some code.

Before this patch if you truncated a file to a smaller size it
wasn't freeing all the blocks properly. There are two reasons.
First, the metapath comparison was not comparing previous heights.
I added a function, mp_eq_to_hgt, which checks the metapath at
all heights prior to the target height.
Second, in function find_nonnull_ptr, it needed to zero out all
pointers for heights following the target height. Translated into
decimal integer terms, this way a number like 299, when incremented,
becomes 300, not 399. The 2 gets incremented to 3, and the following
digits need to be reset.
These two things allow the truncate state machine to properly find
the blocks it needs to delete.

process is removing the neigh entries and the hash table containing them.
However, a representor neigh entry might be linked to the uplink port
hash table and if the uplink nic is cleaned first the cleaning of the
representor will end up in null deref.
Fix that by unloading the representors in the opposite order of load.

Currently if vxlan tunnel ipv6 src isn't supplied the driver fails to
resolve it as part of the route lookup. The resulting encap header
is left with a zeroed out ipv6 src address so the packets are sent
with this src ip.
Use an appropriate route lookup API that also resolves the source
ipv6 address if it's not supplied.

Currently, increasing the number of combined channels is changing
the RSS spread to use the new created channels.
Prevent the RSS spread change in case the user explicitly declare it,
to avoid overriding user configuration.
Tested:
when RSS default:
# ethtool -L ens8 combined 4
RSS spread will change and point to 4 channels.
# ethtool -X ens8 equal 4
# ethtool -L ens8 combined 6
RSS will not change after increasing the number of the channels.

Function mlx5e_dealloc_rx_wqe is using page pointer value as an
indication to valid DMA mapping. In case that the mapping failed, we
released the page but kept the dangling pointer. Store the page pointer
only after the DMA mapping passed to avoid invalid page DMA unmap.
