Commit c6017e793b ("virtio: console: add locks around buffer removal
in port unplug path") added locking around the freeing of buffers in the
vq. However, when free_buf() is called with can_sleep = true and rproc
is enabled, it calls dma_free_coherent() directly, requiring interrupts
to be enabled. Currently a WARNING is triggered due to the spin locking
around free_buf, with a call stack like this:

Updating the event index has a memory barrier and causes more work
on the other side to actually signal the event. It is unnecessary
if a new buffer has already appeared on the ring, so poll once before
doing the update.

invisible, but on the new-style ring it provides a consistent 3%

The following commit 'fad7b7b27b6a (virtio_balloon: Use a workqueue
instead of "vballoon" kthread)' has added a regression. Original code with
kthread starts the thread inside probe and checks the necessity to update
balloon inside the thread immediately.
Nowadays the code behaves differently. Work is queued only on the first
command from the host after the negotiation. Thus there is a window
especially at the guest startup or the module reloading when the balloon
size is not updated until the notification from the host.
This patch adds balloon size check at the end of the probe to match
original behaviour.

Legacy virtio defines the virtqueue base using a 32-bit PFN field, with
a read-only register indicating a fixed page size of 4k.
This can cause problems for DMA allocators that allocate top down from
the DMA mask, which is set to 64 bits. In this case, the addresses are
silently truncated to 44-bit, leading to IOMMU faults, failure to read
from the queue or data corruption.
This patch restricts the coherent DMA mask for legacy PCI virtio devices
to 44 bits, which matches the specification.

When MTU is changed from 9000 to 1500 while there is burst of inbound 9000
bytes packets, adaptor sometimes delivers 9000 bytes packets to 1500 bytes
buffers. This causes memory corruption and sometimes crash.
This is because of a race condition in adaptor between "RQ disable"
clearing descriptor mini-cache and mini-cache valid bit being set by
completion of descriptor fetch. This can result in stale RQ desc being
cached and used when packets arrive. In this case, the stale descriptor
have old MTU value.
Solution is to write RQ->disable twice. The first write will stop any
further desc fetches, allowing the second disable to clear the mini-cache
valid bit without danger of a race.
Also, the check for rq->running becoming 0 after writing rq->enable to 0
is not done properly. When incoming packets are flooding the interface,
rq->running will pulse high for each dropped packet. Since the driver was
waiting for 10us between each poll, it is possible to see rq->running = 1
1000 times in a row, even though it is not actually stuck running.
This results in false failure of vnic_rq_disable(). Fix is to try more
than 1000 time without delay between polls to ensure we do not miss when
running goes low.
In old adaptors rq->enable needs to be re-written to 0 when posted_index
is reset in vnic_rq_clean() in order to keep rq->prefetch_index in sync.

In commit 2d18ac4ba7 ("tipc: extend broadcast link initialization
criteria") we tried to fix a problem with the initial synchronization
of broadcast link acknowledge values. Unfortunately that solution is
not sufficient to solve the issue.
We have seen it happen that LINK_PROTOCOL/STATE packets with a valid
non-zero unicast acknowledge number may bypass BCAST_PROTOCOL
initialization, NAME_DISTRIBUTOR and other STATE packets with invalid
broadcast acknowledge numbers, leading to premature opening of the
broadcast link. When the bypassed packets finally arrive, they are
inadvertently accepted, and the already correctly initialized
acknowledge number in the broadcast receive link is overwritten by
the invalid (zero) value of the said packets. After this the broadcast
link goes stale.
We now fix this by marking the packets where we know the acknowledge
value is or may be invalid, and then ignoring the acks from those.
To this purpose, we claim an unused bit in the header to indicate that
the value is invalid. We set the bit to 1 in the initial BCAST_PROTOCOL
synchronization packet and all initial ("bulk") NAME_DISTRIBUTOR
packets, plus those LINK_PROTOCOL packets sent out before the broadcast
links are fully synchronized.
This minor protocol update is fully backwards compatible.

it with a #define since there is only one TC supported as a default.
Guilherme Piccoli fixes an issue where if we modprobe the driver module
without enough MSI-X interrupts, then unload the module and reload it
again, the kernel would crash. So if we fail to allocate enough MSI-X

mlx4_en_DUMP_ETH_STATS took the *counter mutex* and then
called the FW command, with WRAPPED attribute. As a result, the fw command
is wrapped on the Hypervisor when it calls mlx4_en_DUMP_ETH_STATS.
The FW command wrapper flow on the hypervisor takes the *slave_cmd_mutex*
during processing.
At the same time, a VF could be in the process of coming up, and could
call mlx4_QUERY_FUNC_CAP. On the hypervisor, the command flow takes the
*slave_cmd_mutex*, then executes mlx4_QUERY_FUNC_CAP_wrapper.
mlx4_QUERY_FUNC_CAP wrapper calls mlx4_get_default_counter_index(),
which takes the *counter mutex*. DEADLOCK.
The fix is that the DUMP_ETH_STATS fw command should be called with
the NATIVE attribute, so that on the hypervisor, this command does not
enter the wrapper flow.
Since the Hypervisor no longer goes through the wrapper code, we also
simply return 0 in mlx4_DUMP_ETH_STATS_wrapper (i.e.the function succeeds,
but the returned data will be all zeroes).
No need to test if it is the Hypervisor going through the wrapper.

In the Hypervisor, there are several FW commands which are invoked
before the comm channel is initialized (in mlx4_multi_func_init).
These include MOD_STAT_CONFIG, QUERY_DEV_CAP, INIT_HCA, and others.
If any of these commands fails, say with a timeout, the Hypervisor
driver enters the internal error reset flow. In this flow, the driver
attempts to notify all slaves via the comm channel that an internal error
has occurred.
Since the comm channel has not yet been initialized (i.e., mapped via
ioremap), this will cause dereferencing a NULL pointer.
To fix this, do not access the comm channel in the internal error flow
if it has not yet been initialized.

after INIT_PORT is done and unicast steering is configured.
Before we set priv->port_up NAPI is not scheduled and
receive queues become full. Therefore we never get
new interrupts about the completions.
This issue could happen if running heavy traffic during

The resolution is to schedule NAPI once port_up is set.

rds use Kconfig option called "RDS_DEBUG" to enable rds debug messages.
This option cause the rds Makefile to add -DDEBUG to the rds gcc command
line.
When CONFIG_DYNAMIC_DEBUG is enabled, the "DEBUG" macro is used by
include/linux/dynamic_debug.h to decide if dynamic debug prints should
be sent by default to the kernel log.
rds should not enable this macro for production builds. rds dynamic
debug work as expected follow this fix.

The MAC is capable of RGMII mode and that is probably a more typical
connection type than GMII today (eg it is used by Marvell Reference
designs for several SOCs). Let DT users specify the standard
phy-connection-type = "rgmii-id";

We haven't seen a whole lot of fixes for the first two weeks since the merge
window, but here is the batch that we have at the moment.
Nothing sticks out as particularly bad or scary, it's mostly a handful of
smaller fixes to several platforms. The Uniphier reset controller changes
could probably have been delayed to 4.10, but they're not scary and just
plumbing up driver changes that went in during the merge window.
We're also adding another maintainer to Marvell Berlin platforms, to help
out when Sebastian is too busy. Yay teamwork!

This reverts commit e3f74b841d
("hv_netvsc: report vmbus name in ethtool")'
because of problem introduced by commit f9a56e5d6a0ba
("Drivers: hv: make VMBus bus ids persistent").
This changed the format of the vmbus name and this new format is too
long to fit in the bus_info field of ethtool.
