Pass-through devices to VM guest can get updated IRQ affinity
information via irq_set_affinity() when not running in guest mode.
Currently, AMD IOMMU driver in GA mode ignores the updated information
if the pass-through device is setup to use vAPIC regardless of guest_mode.
This could cause invalid interrupt remapping.
Also, the guest_mode bit should be set and cleared only when
SVM updates posted-interrupt interrupt remapping information.

Just a few minor fixes. Important one is the execbuf async fix (aka
ANDROID_native_sync). There was another patch for a display coherency
corner case on APL, but we've random-walked in that space too much,
and the cherry-pick looked really invasive.

The controller state is set to resetting prior to disabling the
controller, so this patch accounts for that state when deciding if it
needs to freeze the queues. Without this, an 'nvme reset /dev/nvme0'

process_prepared_discard_passdown_pt1() should cleanup
dm_thin_new_mapping in cases of error.
dm_pool_inc_data_range() can fail trying to get a block reference:
metadata operation 'dm_pool_inc_data_range' failed: error = -61
When dm_pool_inc_data_range() fails, dm thin aborts current metadata
transaction and marks pool as PM_READ_ONLY. Memory for thin mapping
is released as well. However, current thin mapping will be queued
onto next stage as part of queue_passdown_pt2() or passdown_endio().
This dangling thin mapping memory when processed and accessed in
next stage will lead to device mapper crashing.
Code flow without fix:
-> process_prepared_discard_passdown_pt1(m)
-> dm_thin_remove_range()
-> discard passdown
--> passdown_endio(m) queues m onto next stage
-> dm_pool_inc_data_range() fails, frees memory m
but does not remove it from next stage queue
-> process_prepared_discard_passdown_pt2(m)
-> processes freed memory m and crashes
One such stack:
Call Trace:

[<ffffffff81530b45>] ret_from_fork+0x25/0x30
The fix is to first take the block ref count for discarded block and
then do a passdown discard of this block. If block ref count fails,
then bail out aborting current metadata transaction, mark pool as
PM_READ_ONLY and also free current thin mapping memory (existing error
handling code) without queueing this thin mapping onto next stage of
processing. If block ref count succeeds, then passdown discard of this
block. Discard callback of passdown_endio() will queue this thin mapping
onto next stage of processing.
Code flow with fix:
-> process_prepared_discard_passdown_pt1(m)
-> dm_thin_remove_range()
-> dm_pool_inc_data_range()
--> if fails, free memory m and bail out
-> discard passdown
--> passdown_endio(m) queues m onto next stage

If we write a relocation into the buffer, we require our own implicit
synchronisation added after the start of the execbuf, outside of the
user's control. As we may end up clflushing, or doing the patch itself
on the GPU, asynchronously we need to look at the implicit serialisation
on obj->resv and hence need to disable EXEC_OBJECT_ASYNC for this
object.
If the user does trigger a stall for relocations, we make sure the stall
is complete enough so that the batch is not submitted before we complete
those relocations.

Since we may track unfenced access (GPU access to the vma that

To handle netpoll properly, the driver must only handle TX packets
during NAPI. Handling RX events cause warnings and errors in
netpoll mode. The ndo_poll_controller() method should call
napi_schedule() directly so that a NAPI weight of zero will be used
during netpoll mode.
The bnxt_en driver supports 2 ring modes: combined, and separate rx/tx.
In separate rx/tx mode, the ndo_poll_controller() method will only
process the tx rings. In combined mode, the rx and tx completion
entries are mixed in the completion ring and we need to drop the rx
entries and recycle the rx buffers.
Add a function bnxt_force_rx_discard() to handle this in netpoll mode
when we see rx entries in combined ring mode.

Passthru macvlans directly change the mac address of the lower
level device. That's OK, but after the macvlan is deleted,
the lower device is left with changed address and one needs to
reboot to bring back the origina HW addresses.
This scenario is actually quite common with passthru macvtap devices.
This patch attempts to solve this, by storing the mac address
of the lower device in macvlan_port structure and keeping track of
it through the changes.
After this patch, any changes to the lower device mac address
done trough the macvlan device, will be reverted back. Any

When a lower device of the passthru macvlan changes it's address,
passthru macvlan is supposed to change it's own address as well.
However, that doesn't happen correctly because the check in
macvlan_addr_busy() will catch the fact that the lower level
(port) mac address is the same as the address we are trying to
assign to the macvlan, and return an error. As a reasult,
the address of the passthru macvlan device is never changed.
The same thing happens when the user attempts to change the
mac address of the passthru macvlan.
The simple solution appers to be to not check against
the lower device in case of passthru macvlan device, since
the 2 addresses are _supposed_ to be the same.

The user currently gets an EBUSY error when attempting to set
the mac address on a macvlan device to the same value.
This should really be a no-op as nothing changes. Catch
the condition and return early.

Add a flag to indicate if a queue is rate-limited. Test the flag in
NAPI poll handler and avoid rescheduling the queue if true, otherwise
we risk locking up the host. The rescheduling will be done in the
timer callback function.

There are number of problems with configuration peer
network device in absence of IFLA_VETH_PEER attributes
where attributes for main network device shared with
peer.
First it is not feasible to configure both network
devices with same MAC address since this makes
communication in such configuration problematic.
This case can be reproduced with following sequence:
# ip link add address 02:11:22:33:44:55 type veth
# ip li sh
...
26: veth0@veth1: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc \
noop state DOWN mode DEFAULT qlen 1000
link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff
27: veth1@veth0: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc \
noop state DOWN mode DEFAULT qlen 1000
link/ether 00:11:22:33:44:55 brd ff:ff:ff:ff:ff:ff
Second it is not possible to register both main and
peer network devices with same name, that happens
when name for main interface is given with IFLA_IFNAME
and same attribute reused for peer.
This case can be reproduced with following sequence:
# ip link add dev veth1a type veth
RTNETLINK answers: File exists
To fix both of the cases check if corresponding netlink
attributes are taken from peer_tb when valid or
name based on rtnl ops kind and random address is used.

cpsw driver tries to get macid for am43xx SoCs using the compatible
ti,am4372. But not all variants of am43x uses this complatible like
epos evm uses ti,am438x. So use a generic compatible ti,am43 to get
macid for all am43 based platforms.

The commit ("net/phy: micrel: Add workaround for bad autoneg") fixes an
autoneg failure case by resetting the hardware. This turns off
intterupts. Things will work themselves out if the phy polls, as it will
figure out it's state during a poll. However if the phy uses only
intterupts, the phy will stall, since interrupts are off. This patch
fixes the issue by calling config_intr after resetting the phy.

The i2c-imx driver incorrectly uses readb()/writeb() to read and
write to the appropriate registers when performing a repeated start.
The appropriate imx_i2c_read_reg()/imx_i2c_write_reg() functions
should be used instead. Performing a repeated start results in
a kernel panic. The platform is imx.

Pull block fixes from Jens Axboe:
"This contains a set of fixes for xen-blkback by way of Konrad, and a
performance regression fix for blk-mq for shared tags.
The latter could account for as much as a 50x reduction in
performance, with the test case from the user with 500 name spaces. A
more realistic setup on my end with 32 drives showed a 3.5x drop. The
fix has been thoroughly tested before being committed"

Commit f406270bf73d ("ACPI / scan: Set the visited flag for all
enumerated devices") caused that two group of special SPI or I2C
devices do not enumerate. SPI and I2C devices are expected to be
enumerated by the SPI and I2C subsystems but change caused that
acpi_bus_attach() marks those devices with acpi_device_set_enumerated().
First group of devices are matched using Device Tree compatible property
with special _HID "PRP0001". Those devices have matched scan handler,
acpi_scan_attach_handler() retuns 1 and acpi_bus_attach() marks them
with acpi_device_set_enumerated().
Second group of devices without valid _HID such as "LNXVIDEO" have
device->pnp.type.platform_id set to zero and change again marks them
with acpi_device_set_enumerated().
Fix this by flagging the SPI and I2C devices during struct acpi_device
object initialization time and let the code in acpi_bus_attach() to go
through the device_attach() and acpi_default_enumeration() path for all
SPI and I2C devices.
