The old style of memory interleaving swizzled upto the end of the
first even bank of memory, and then used the remainder as unswizzled on
the unpaired bank - i.e. swizzling is not constant for all memory. This
causes problems when we try to migrate memory and so the kernel prevents
migration at all when we detect L-shaped inconsistent swizzling.
However, this issue also extends to userspace who try to manually detile
into memory as the swizzling for an individual page is unknown (it
depends on its physical address only known to the kernel), userspace
cannot correctly swizzle.
Note that this is a new attempt for the previously merged one,
reverted in

If the device does not support the aliasing ppgtt, we must translate
user bind requests (PIN_USER) from LOCAL_BIND to a GLOBAL_BIND. However,
since this is device specific we cannot do this conveniently in the
upper layers and so must manage the vma->bound flags in the backend.

This patch fix a possible race after calling register_netdev. After
calling netdev_register it could be possible that netdev_ops callbacks
use the uninitialized private data of lowpan_dev. By moving the
initialization of this data before netdev_register we can be sure that
initialized private data is be used after netdev_register.

When transmitting a packet via a mac802154 driver that can sleep in
its transmit function, mac802154 defers the call to the driver's
transmit function to a per-device workqueue.
However, mac802154 uses a single global work_struct for this, which
means that if you have more than one registered mac802154 interface
in the system, and you transmit on more than one of them at the same
time, you'll very easily cause memory corruption.
This patch moves the deferred transmit processing state from global
variables to struct ieee802154_local, and this seems to fix the memory
corruption issue.

btusb currently has a generic match on USB device descriptors:
{ USB_DEVICE_INFO(0xe0, 0x01, 0x01) },
However, http://www.usb.org/developers/defined_class states:
Base Class E0h (Wireless Controller)
This base class is defined for devices that are Wireless controllers.
Values not shown in the table below are reserved. These class codes are
to be used in Interface Descriptors, with the exception of the Bluetooth
class code which can also be used in a Device Descriptor.
Add a match on the interface descriptors accordingly.
This fixes compatibility with the RTL8723AU device shown below.
This device conforms to the USB Interface Association Descriptor
specification, which requires the device to have class ef/02/01.
The extra IAD descriptor then specifies that interfaces 0 and 1
belong to the same function/driver, which is true. Provided that
the Bluetooth device class spec accepts use of the IAD, I imagine that
technically, all btusb devices should be configured like this.

Currently nf_conntrack_proto_sctp module handles only packets between
primary addresses used to establish the connection. Any packets between
secondary addresses are classified as invalid so that usual firewall
configurations drop them. Allowing HEARTBEAT and HEARTBEAT-ACK chunks to
establish a new conntrack would allow traffic between secondary
addresses to pass through. A more sophisticated solution based on the
addresses advertised in the initial handshake (and possibly also later
dynamic address addition and removal) would be much harder to implement.
Moreover, in general we cannot assume to always see the initial
handshake as it can be routed through a different path.
The patch adds two new conntrack states:
SCTP_CONNTRACK_HEARTBEAT_SENT - a HEARTBEAT chunk seen but not acked
SCTP_CONNTRACK_HEARTBEAT_ACKED - a HEARTBEAT acked by HEARTBEAT-ACK
State transition rules:
- HEARTBEAT_SENT responds to usual chunks the same way as NONE (so that
the behaviour changes as little as possible)
- HEARTBEAT_ACKED responds to usual chunks the same way as ESTABLISHED
does, except the resulting state is HEARTBEAT_ACKED rather than
ESTABLISHED
- previously existing states except NONE are preserved when HEARTBEAT or
HEARTBEAT-ACK is seen
- NONE (in the initial direction) changes to HEARTBEAT_SENT on HEARTBEAT
and to CLOSED on HEARTBEAT-ACK
- HEARTBEAT_SENT changes to HEARTBEAT_ACKED on HEARTBEAT-ACK in the
reply direction
- HEARTBEAT_SENT and HEARTBEAT_ACKED are preserved on HEARTBEAT and
HEARTBEAT-ACK otherwise
Normally, vtag is set from the INIT chunk for the reply direction and
from the INIT-ACK chunk for the originating direction (i.e. each of
these defines vtag value for the opposite direction). For secondary
conntracks, we can't rely on seeing INIT/INIT-ACK and even if we have
seen them, we would need to connect two different conntracks. Therefore
simplified logic is applied: vtag of first packet in each direction
(HEARTBEAT in the originating and HEARTBEAT-ACK in reply direction) is
saved and all following packets in that direction are compared with this
saved value. While INIT and INIT-ACK define vtag for the opposite
direction, vtags extracted from HEARTBEAT and HEARTBEAT-ACK are always
for their direction.
Default timeout values for new states are
HEARTBEAT_SENT: 30 seconds (default hb_interval)
HEARTBEAT_ACKED: 210 seconds (hb_interval * path_max_retry + max_rto)
(We cannot expect to see the shutdown sequence so that, unlike
ESTABLISHED, the HEARTBEAT_ACKED timeout shouldn't be too long.)

Some AMD systems also have non-PCI devices which can do DMA.
Those can't be handled by the AMD IOMMU, as the hardware can
only handle PCI. These devices would end up with no dma_ops,

set. SWIOTLB provides global dma_ops when it is active, so
make sure there are global dma_ops too when swiotlb is

Introduce Mellanox Technologies Switch ASICs switchdev drivers
This patchset introduces Mellanox Technologies Switch driver infrastructure
and support for SwitchX-2 ASIC.
The driver is divided into 3 logical parts:
1) Bus - implements switch bus interface. Currently only PCI bus is
implemented, but more buses will be added in the future. Namely I2C
and SGMII.
(patch #2)
2) Driver - implemements of ASIC-specific functions.
Currently SwitchX-2 ASIC is supported, but a plan exists to introduce
support for Spectrum ASIC in the near future.
(patch #4)
3) Core - infrastructure that glues buses and drivers together.
It implements register access logic (EMADs) and takes care of RX traps
and events.

Ethernet Management Datagrams (EMADs) are Ethernet packets sent between

Another use case is notifications sent from the device to the host,
letting it know about certain events, such as port up / down.
Add the ability to construct EMADs with provisions to construct and
parse the registers' payloads. Implement EMAD transaction layer
which is responsible for the reliable transmission of EMADs. Also, add

With earlier configured value sufficient number of CQEs are not

traffic load, receive notifications will take away most of the CQ
thus transmit notifications will be lost resulting in tx skbs not
being freed.
Finally SQ will be full and it will be stopped, watchdog timer
will kick in. After this fix receive notifications will not take
morethan half of CQ reserving the rest for transmit notifications.
Also changed CQ & SQ sizes from 16k to 4k.
This is also due to the receive notifications taking first half of

We chose to remove it for two reasons:
1) It requires additional instance of struct mlx5e_params on the
stack and looking forward we expect this struct to grow.
2) Sometimes we want to do additional operations (besides
just updating the priv parameters) while the netdev is stopped.
For example, updating netdev->mtu @mlx5e_change_mtu() should
