another fix that was causing issues.
We are still tracking one crash in v4.12-rc7, but only one person has

In case a VLAN device is enslaved to a bridge we shouldn't create a
router interface (RIF) for it when it's configured with an IP address.
This is already handled by the driver for other types of netdevs, such
as physical ports and LAG devices.
If this IP address is then removed and the interface is subsequently
unlinked from the bridge, a NULL pointer dereference can happen, as the
original 802.1d FID was replaced with an rFID which was then deleted.
To reproduce:
$ ip link set dev enp3s0np9 up
$ ip link add name enp3s0np9.111 link enp3s0np9 type vlan id 111
$ ip link set dev enp3s0np9.111 up
$ ip link add name br0 type bridge
$ ip link set dev br0 up
$ ip link set enp3s0np9.111 master br0
$ ip address add dev enp3s0np9.111 192.168.0.1/24

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

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.

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

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.

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.

The function, skb_complete_tx_timestamp(), used to allow passing in a
NULL pointer for the time stamps, but that was changed in commit
62bccb8cdb ("net-timestamp: Make the
clone operation stand-alone from phy timestamping"), and the existing
call sites, all of which are in the dp83640 driver, were fixed up.
Even though the kernel-doc was subsequently updated in commit
7a76a021cd ("net-timestamp: Update
skb_complete_tx_timestamp comment"), still a bug fix from Manfred
Rudigier came into the driver using the old semantics. Probably
Manfred derived that patch from an older kernel version.
This fix should be applied to the stable trees as well.

All the other accesses to superblock fields new in 1.9.0 were reviewed
