HP Elite Dragonfly G2 (a convertible laptop/tablet) has a reliable VGBS
method. If VGBS is not called on boot, the firmware sends an initial
0xcd event shortly after calling the BTNL method, but only if the device
is booted in the laptop mode. However, if the device is booted in the
tablet mode and VGBS is not called, there is no initial 0xcc event, and
the input device for SW_TABLET_MODE is not registered up until the user
turns the device into the laptop mode.
Call VGBS on boot on this device to get the initial state of
SW_TABLET_MODE in a reliable way.
Tested with BIOS 1.13.1.

On a HP Elite Dragonfly G2 the 0xcc and 0xcd events for SW_TABLET_MODE
are only send after the BTNL ACPI method has been called.
Likely more devices need this, so make the BTNL ACPI method unconditional
instead of only doing it on devices with a 5 button array.
Note this also makes the intel_button_array_enable() call in probe()
unconditional, that function does its own priv->array check. This makes
the intel_button_array_enable() call in probe() consistent with the calls
done on suspend/resume which also rely on the priv->array check inside
the function.

commit a3a57bf07de23fe1ff779e0fdf710aa581c3ff73 ("net: stmmac: work
around sporadic tx issue on link-up") worked around a problem with TX
sometimes not working after a link-up by avoiding a redundant write to
MAC_CTRL_REG (aka GMAC_CONFIG), since the IP appeared to have problems
with handling multiple writes to that register in some cases.
That commit however only added the work around to dwmac_lib.c (apart
from the common code in stmmac_main.c), but my systems with version
4.21a of the IP exhibit the same problem, so add the work around to
dwmac4_lib.c too.

As of today, hash extraction support is enabled for all the silicons.
Because of which we are facing initialization issues when the silicon
does not support hash extraction. During creation of the hardware
parsing table for IPv6 address, we need to consider if hash extraction
is enabled then extract only 32 bit, otherwise 128 bit needs to be
extracted. This patch fixes the issue and configures the hardware parser
based on the availability of the feature.

When adding a point to point downlink to team device, we neglected to reset
the team's flags, which were still using flags like BROADCAST and
MULTICAST. Consequently, this would initiate ARP/DAD for P2P downlink
interfaces, such as when adding a GRE device to team device. Fix this by
remove multicast/broadcast flags and add p2p and noarp flags.
After removing the none ethernet interface and adding an ethernet interface
to team, we need to reset team interface flags. Unlike bonding interface,
team do not need restore IFF_MASTER, IFF_SLAVE flags.

According to the implementation of XDP of FEC driver, the XDP path
shares the transmit queues with the kernel network stack, so it is
possible to lead to a tx timeout event when XDP uses the tx queue
pretty much exclusively. And this event will cause the reset of the
FEC hardware.
To avoid timeout in this case, we use the txq_trans_cond_update()
interface to update txq->trans_start to jiffies so that watchdog
won't generate a transmit timeout warning.

The DASD driver has certain types of requests that might be rejected by
the storage server or z/VM because they are not supported. Since the
missing support of the command is not a real issue there is no user
visible kernel error message for this.
For copy pair setups there is a specific error that IO is not allowed on
secondary devices. This error case is explicitly handled and an error
message is printed.
The code checking for the error did use a bitwise 'and' that is used to
check for specific bits. But in this case the whole sense byte has to
match.
This leads to the problem that the copy pair related error message is
erroneously printed for other error cases that are usually not reported.
This might heavily confuse users and lead to follow on actions that might
disrupt application processing.
Fix by checking the sense byte for the exact value and not single bits.

The DASD device driver has a function to requeue requests to the
blocklayer.
This function is used in various cases when basic settings for the device
have to be changed like High Performance Ficon related parameters or copy
pair settings.
The functions iterates over the device->ccw_queue and also removes the
requests from the block->ccw_queue.
In case the device is started on an alias device instead of the base
device it might be removed from the block->ccw_queue without having it
canceled properly before. This might lead to a hanging device since the
request is no longer on a queue and can not be handled properly.
Fix by iterating over the block->ccw_queue instead of the
device->ccw_queue. This will take care of all blocklayer related requests
and handle them on all associated DASD devices.

If a DASD request fails an error recovery procedure (ERP) request might
be built as a copy of the original request to do error recovery.
The ERP request gets a number of retries assigned.
This number is always 256 no matter what other value might have been set
for the original request. This is not what is expected when a user
specifies a certain amount of retries for the device via sysfs.

Quiesce and resume are functions that tell the DASD driver to stop/resume
issuing I/Os to a specific DASD.
On resume dasd_schedule_block_bh() is called to kick handling of IO
requests again. This does unfortunately not cover internal requests which
are used for path verification for example.
This could lead to a hanging device when a path event or anything else
that triggers internal requests occurs on a quiesced device.
Fix by also calling dasd_schedule_device_bh() which triggers handling of
internal requests on resume.

VXLAN-GPE does not add an extra inner Ethernet header. Take that into
account when calculating header length.
This causes problems in skb_tunnel_check_pmtu, where incorrect PMTU is
cached.
In the collect_md mode (which is the only mode that VXLAN-GPE
supports), there's no magic auto-setting of the tunnel interface MTU.
It can't be, since the destination and thus the underlying interface
may be different for each packet.
So, the administrator is responsible for setting the correct tunnel
interface MTU. Apparently, the administrators are capable enough to
calculate that the maximum MTU for VXLAN-GPE is (their_lower_MTU - 36).
They set the tunnel interface MTU to 1464. If you run a TCP stream over
such interface, it's then segmented according to the MTU 1464, i.e.
producing 1514 bytes frames. Which is okay, this still fits the lower
MTU.
However, skb_tunnel_check_pmtu (called from vxlan_xmit_one) uses 50 as
the header size and thus incorrectly calculates the frame size to be
1528. This leads to ICMP too big message being generated (locally),
PMTU of 1450 to be cached and the TCP stream to be resegmented.
The fix is to use the correct actual header size, especially for
skb_tunnel_check_pmtu calculation.

The decision whether to enable a wake irq during suspend can not be done
based on the runtime PM state directly as a driver may use wake irqs
without implementing runtime PM. Such drivers specifically leave the
state set to the default 'suspended' and the wake irq is thus never
enabled at suspend.
Add a new wake irq flag to track whether a dedicated wake irq has been
enabled at runtime suspend and therefore must not be enabled at system
suspend.
Note that pm_runtime_enabled() can not be used as runtime PM is always
disabled during late suspend.

and this value is used to set max_sectors for the synthetic SCSI
controller. However, this max transfer size may be too large for virtual
Fibre Channel devices, which are limited to 512 Kbytes. If a larger
transfer size is used with a vFC device, Hyper-V always returns an error,
and storvsc logs a message like this where the SRB status and SCSI status
are both zero:

Pull regmap fixes from Mark Brown:
"Three fixes here:
- The issues with accounting for register and padding length on raw
buses turn out to be quite widespread in custom buses.
In order to avoid disturbing anything drop the initial fixes and
fall back to a point fix in the SMBus code where the issue was
originally noticed, a more substantial refactoring of the API which
ensures that all buses make the same assumptions will follow.
- The generic regcache code had been forcing on async I/O which did
not work with the new maple tree sync code when used with SPI.
Since that was mainly for the rbtree cache and the assumptions
about hardware that drove the choice are probably not true any more
fix this by pushing the enablement of async down into the rbtree
code.
This probably also makes cache syncs for systems faster though it's
not the point.
- The test code was triggering use of the rbtree and maple tree
caches with dynamic allocation of nodes since all the testing is
with RAM backed caches with no I/O performance issues.
Just disable the locking in the tests to avoid triggering warnings
when allocation debugging is turned on, it's not really what's
being tested"
