[ Upstream commit e81b889329 ]
Intel Cherry Trail Whiskey Cove extcon driver connect USB data lines to
PMIC at driver probing for further charger detection. This causes reset of
USB data sessions and removing all devices from bus. If system was
booted from Live CD or USB dongle, this makes system unusable.
Check if USB ID pin is floating and re-route data lines in this case
only, don't touch otherwise.

The `connected` value for wired devices was not properly initialized,
it must be set to `true` upon creation, because wired devices do not
generate connection events.
When a raw client (the Steam Client) uses the device, the input device
is destroyed. Then, when the raw client finishes, it must be recreated.
But since the `connected` variable was false this never happended.

For high-res (8K) or HFR (4K120) displays, using uncompressed pixel
formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the
"interesting" modes would be disabled, leaving only low-res or low
framerate modes.
This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS

[ Upstream commit f11421ba4a ]
Atomic operations that span cache lines are super-expensive on x86
(not just to the current processor, but also to other processes as all
memory operations are blocked until the operation completes). Upcoming
x86 processors have a switch to cause such operations to generate a #AC
trap. It is expected that some real time systems will enable this mode
in BIOS.
In preparation for this, it is necessary to fix code that may execute
atomic instructions with operands that cross cachelines because the #AC
trap will crash the kernel.
Since "pwol_mask" is local and never exposed to concurrency, there is
no need to set bits in pwol_mask using atomic operations.
Directly operate on the byte which contains the bit instead of using
__set_bit() to avoid any big endian concern due to type cast to
unsigned long in __set_bit().

iowrite32be() called from gve_rx_write_doorbell()/gve_tx_put_doorbell()

E.g. On ARM64, iowrite32be() calls __iowmb() which expands to dma_wmb()

[ Upstream commit 63078b6ba0 ]
The micro-USB connector on Motorola Mapphone devices can be muxed between
the SoC and the mdm6600 modem. But even when used for the SoC, configuring
the PHY with ID pin grounded will wake up the modem from idle state. Looks
like the issue is probably caused by line glitches.
We can prevent the glitches by using a previously unknown mode of the
GPIO mux to prevent the USB lines from being connected to the moden while
configuring the USB PHY, and enable the USB lines after configuring the
PHY.
Note that this only prevents waking up mdm6600 as regular USB A-host mode,
and does not help when connected to a lapdock. The lapdock specific issue
still needs to be debugged separately.

The subpacket scanning loop in rxrpc_receive_data() references the
subpacket count in the private data part of the sk_buff in the loop
termination condition. However, when the final subpacket is pasted into
the ring buffer, the function is no longer has a ref on the sk_buff and
should not be looking at sp->* any more. This point is actually marked in
the code when skb is cleared (but sp is not - which is an error).
Fix this by caching sp->nr_subpackets in a local variable and using that
instead.
Also clear 'sp' to catch accesses after that point.
This can show up as an oops in rxrpc_get_skb() if sp->nr_subpackets gets
trashed by the sk_buff getting freed and reused in the meantime.

where filters are installed on qdisc 1:0, so we can't merely
search from class 1:1 when creating class 1:3 and class 1:4. We have
to walk through all the child classes of the direct parent qdisc.
Otherwise we would miss filters those need reverse binding.

[ Upstream commit 2e24cd7555 ]
The current implementations of ops->bind_class() are merely
searching for classid and updating class in the struct tcf_result,
without invoking either of cl_ops->bind_tcf() or
cl_ops->unbind_tcf(). This breaks the design of them as qdisc's
like cbq use them to count filters too. This is why syzbot triggered
the warning in cbq_destroy_class().
In order to fix this, we have to call cl_ops->bind_tcf() and
cl_ops->unbind_tcf() like the filter binding path. This patch does
so by refactoring out two helper functions __tcf_bind_filter()
and __tcf_unbind_filter(), which are lockless and accept a Qdisc
pointer, then teaching each implementation to call them correctly.
Note, we merely pass the Qdisc pointer as an opaque pointer to
each filter, they only need to pass it down to the helper
functions without understanding it at all.

commit 2d68bb2687 upstream.
Make sure to use the current alternate setting when verifying the
storage interface descriptors to avoid submitting an URB to an invalid
endpoint.
Failing to do so could cause the driver to misbehave or trigger a WARN()
in usb_submit_urb() that kernels with panic_on_warn set would choke on.

commit bd56cea012 upstream.
The chelsio crypto driver is casting 'struct crypto_aead' directly to
'struct crypto_tfm', which is incorrect because the crypto_tfm isn't the
first field of 'struct crypto_aead'. Consequently, the calls to
crypto_tfm_set_flags() are modifying some other field in the struct.
Also, the driver is setting CRYPTO_TFM_RES_BAD_KEY_LEN in
->setauthsize(), not just in ->setkey(). This is incorrect since this
flag is for bad key lengths, not for bad authentication tag lengths.
Fix these bugs by removing the broken crypto_tfm_set_flags() calls from
->setauthsize() and by fixing them in ->setkey().

commit 264d25275a upstream.
Since commit 57ea974fb8 ("driver core: Rewrite test_async_driver_probe
to cover serialization and NUMA affinity"), running the test with NUMA
disabled results in warning messages similar to the following.
test_async_driver test_async_driver.12: NUMA node mismatch -1 != 0
If CONFIG_NUMA=n, dev_to_node(dev) returns -1, and numa_node_id()
returns 0. Both are widely used, so it appears risky to change return
values. Augment the check with IS_ENABLED(CONFIG_NUMA) instead
to fix the problem.
