[ Upstream commit 1a581b7216 ]
dm is a bit special in that it opens the underlying devices. Commit
89f871af1b ("dm: delay registering the gendisk") tried to accommodate
that by allowing to add the holder to the list before add_gendisk and
then just add them to sysfs once add_disk is called. But that leads to
really odd lifetime problems and error handling problems as we can't
know the state of the kobjects and don't unwind properly. To fix this
switch to just registering all existing table_devices with the holder
code right after add_disk, and remove them before calling del_gendisk.

[ Upstream commit cc26516374 ]
Currently the fallback SG allocation tries to allocate each single
page, and this tends to result in the reverse order of memory
addresses when large space is available at boot, as the kernel takes a
free page from the top to the bottom in the zone. The end result
looks as if non-contiguous (although it actually is). What's worse is
that it leads to an overflow of BDL entries for HD-audio.
For avoiding such a problem, this patch modifies the allocation code
slightly; now it tries to allocate the larger contiguous chunks as
much as possible, then reduces to the smaller chunks only if the
allocation failed -- a similar strategy as the existing
snd_dma_alloc_pages_fallback() function.
Along with the trick, drop the unused address array from
snd_dma_sg_fallback object. It was needed in the past when
dma_alloc_coherent() was used, but with the standard page allocator,
it became superfluous and never referred.

The AMT_STATE sap message handler tries to take the rtnl lock.
This means that in case the rtnl lock is already taken, sap messages

When an interface is brought up, the host requests ownership from
csme. However, since the rtnl lock is already held, if there is a
pending amt state message, the host will not be able to read the
ownership confirm message because the amt state message handler
is pending. As a result, the host fails to get ownership although
csme granted it.

after the driver started unregistering, the iwl_mei_cache->ops is

confirmed message.
Similarly, if the take ownership message arrived after the mac was
stopped or when iwl_mvm_up() failed, setting rfkill will not trigger
sending the confirm message. As a result, CSME will not take
ownership, which will result in a disconnection.

bfq_init_rq() expects a brand new allocated queue to be returned from
bfq_get_bfqq_handle_split() and unconditionally updates waker_bfqq
without resetting woken_list_node. Since we can always return oom_bfqq
when attempting to allocate, we cannot assume waker_bfqq starts as NULL.

So use this helper, which sets both.

In case the LCDIFv3 is used to drive a 4k panel via i.MX8MP HDMI bridge,
the LCDIFv3 becomes susceptible to FIFO underflows, these lead to nasty
flicker of the image on the panel, or image being shifted by half frame
horizontally every second frame. The flicker can be easily triggered by
running 3D application on top of weston compositor, like neverball or
chromium. Surprisingly glmark2-es2-wayland or glmark2-es2-drm does not
trigger this effect so easily.
Configure the FIFO Panic threshold register and enable the FIFO Panic
mode, which internally boosts the NoC interconnect priority for LCDIFv3
transactions in case of possible underflow. This mitigates the flicker
effect on 4k panels as well.

[ Upstream commit b8f6efccbb ]
When using wpa_supplicant v2.10, this driver is no longer able to
associate with any AP and fails in the EAPOL 4-way handshake while
sending the 2/4 message to the AP. The problem is not present in
wpa_supplicant v2.9 or older. The problem stems from HostAP commit
144314eaa ("wpa_supplicant: Send EAPOL frames over nl80211 where available")
which changes the way EAPOL frames are sent, from them being send
at L2 frames to them being sent via nl80211 control port.
An EAPOL frame sent as L2 frame is passed to the WiFi driver with
skb->protocol ETH_P_PAE, while EAPOL frame sent via nl80211 control
port has skb->protocol set to ETH_P_802_3 . The later happens in
ieee80211_tx_control_port(), where the EAPOL frame is encapsulated
into 802.3 frame.
The rsi_91x driver handles ETH_P_PAE EAPOL frames as high-priority
frames and sends them via highest-priority transmit queue, while
the ETH_P_802_3 frames are sent as regular frames. The EAPOL 4-way
handshake frames must be sent as highest-priority, otherwise the
4-way handshake times out.
Therefore, to fix this problem, inspect the skb control flags and
if flag IEEE80211_TX_CTRL_PORT_CTRL_PROTO is set, assume this is
an EAPOL frame and transmit the frame via high-priority queue just
like other ETH_P_PAE frames.

kobject_add_internal failed for mtd-0 with -EEXIST, don't try to register
things with the same name in the same directory.
Error registering mtd class or bdi: -17
If init_mtdchar() fails in init_mtd(), mtd_bdi will not be unregistered,
as a result, we can't load the mtd module again, to fix this by calling
bdi_unregister(mtd_bdi) after out_procfs label.
Fixes: 445caaa20c ("mtd: Allocate bdi objects dynamically")
