Check within geneve_xmit_skb/geneve6_xmit_skb that sk_buff structure
is large enough to include IPv4 or IPv6 header, and reject if not. The
geneve_xmit_skb portion and overall idea was contributed by Eric Dumazet.

When the probe fails, we must disable the regulator that was previously
enabled.
This patch is a follow-up to commit ac88c531a5b3
("net: davicom: Fix regulator not turned off on failed probe") which missed
one case.

MHI changes for v5.13
core:
- Added support for Flash Programmer execution environment which allows the
host machine (like x86) to flash the modem firmware to NAND or eMMC in the
modem. The MHI bus will expose EDL channels (34, 35) and then the opensource
QDL tool [1] can be used to flash the firmware from the host.
- Added an internal helper for polling the MHI registers with a retry interval.
This helper is used now to poll for the MHI ready state in MHI STATUS
register.
- Various fixes for issues found during the bringup of SDX24/SDX55 based Quectel
and Telit modems.
- Updates to the Execution environment handling for proper downloading of the
AMSS image from SBL (Secondary Bootloader) mode.
- Added support for sending STOP channel command to the MHI device and also made
changes to the MHI core for proper handling of stop and restart.
- Fixed the runtime_pm handling in the core by forcing the device to be in wake
mode until TX completion and allowing it to suspend for RX.
- Added sanity checks for values read from the device to avoid crash if those
are corrupted somehow.
- Fixed warnings generated by sparse (W=2)
- Couple of kernel doc cleanups in mhi.h
pci_generic:
- Added support for runtime PM and generic PM
- Added Firehose channels for flashing the firmware
- Added support for modems such as Quectel EM1XXGR-L, SDX24, SDX65, Foxconn
T99W175 exposing relevant channels.

This tag contains habanalabs driver changes for v5.13:
- Add support to reset device after the user closes the file descriptor.
Because we support a single user, we can reset the device (if needs to)
after a user closes its file descriptor to make sure the device is in
idle and clean state for the next user.
- Add a new feature to allow the user to wait on interrupt. This is needed
for future ASICs
- Replace GFP_ATOMIC with GFP_KERNEL wherever possible and add code to
support failure of allocating with GFP_ATOMIC.
- Update code to support the latest firmware image:
- More security features are done in the firmware
- Remove hard-coded assumptions and replace them with values that are
sent to the firmware on loading.
- Print device unusable error
- Reset device in case the communication between driver and firmware
gets out of sync.
- Support new PCI device ids for secured GAUDI.
- Expose current power draw through the INFO IOCTL.
- Support resetting the device upon a request from the BMC (through F/W).
- Always use only a single MSI in GAUDI, due to H/W limitation.
- Improve data-path code by taking out code from spinlock protection.
- Allow user to specify custom timeout per Command Submission.
- Some enhancements to debugfs.
- Various minor changes and improvements.

When async binder buffer got exhausted, some normal oneway transactions
will also be discarded and may cause system or application failures. By
that time, the binder debug information we dump may not be relevant to
the root cause. And this issue is difficult to debug if without the
backtrace of the thread sending spam.
This change will send BR_ONEWAY_SPAM_SUSPECT to userspace when oneway
spamming is detected, request to dump current backtrace. Oneway spamming
will be reported only once when exceeding the threshold (target process
dips below 80% of its oneway space, and current process is responsible for
either more than 50 transactions, or more than 50% of the oneway space).
And the detection will restart when the async buffer has returned to a
healthy state.

In case a platform doesn't provide explicit flush-hints but provides an
explicit flush callback via ND_REGION_ASYNC region flag, then
nvdimm_has_flush() still returns '0' indicating that writes do not
require flushing. This happens on PPC64 with patch at [1] applied, where
'deep_flush' of a region was denied even though an explicit flush
function was provided.
Fix this by adding a condition to nvdimm_has_flush() to test for the
ND_REGION_ASYNC flag on the region and see if a 'region->flush' callback
is assigned.

the value of RX_HEAD_PADDING, this may result in ethernet frames
that are too short (cut off at the end), or too long (garbage added
to the end).
Fix by calculating the ethernet frame length correctly. For added
clarity, use the ETH_FCS_LEN constant in the calculation.
Many thanks to Heiner Kallweit for suggesting this solution.

[<vendor>,]nr-gpios property is used by some GPIO drivers[0] to indicate
the number of GPIOs present on a system, not define a GPIO. nr-gpios is
not configured by #gpio-cells and can't be parsed along with other
"*-gpios" properties.
nr-gpios without the "<vendor>," prefix is not allowed by the DT
spec[1], so only add exception for the ",nr-gpios" suffix and let the
error message continue being printed for non-compliant implementations.

When we suspend the VM, the VDPA interface will be reset. When the VM is
resumed again, clear_virtqueues() will clear the available and used
indices resulting in hardware virqtqueue objects becoming out of sync.
We can avoid this function alltogether since qemu will clear them if
required, e.g. when the VM went through a reboot.
Moreover, since the hw available and used indices should always be
identical on query and should be restored to the same value same value
for virtqueues that complete in order, we set the single value provided
by set_vq_state(). In get_vq_state() we return the value of hardware
used index.

When feature VIRTIO_NET_F_MTU is negotiated on mlx5_vdpa,
22 extra bytes worth of MTU length is shown in guest.
This is because the mlx5_query_port_max_mtu API returns
the "hardware" MTU value, which does not just contain the
Ethernet payload, but includes extra lengths starting
from the Ethernet header up to the FCS altogether.
Fix the MTU so packets won't get dropped silently.

drivers/usb/core/hub.c: usb_new_device() contains the following:
/* By default, forbid autosuspend for all devices. It will be
* allowed for hubs during binding.
*/
usb_disable_autosuspend(udev);
So for anything which is not a hub, such as btusb devices, autosuspend is
disabled by default and we must call usb_enable_autosuspend(udev) to
enable it.
This means that the "Fix the autosuspend enable and disable" commit,
which drops the usb_enable_autosuspend() call when the enable_autosuspend
module option is true, is completely wrong, revert it.
This reverts commit 7bd9fb058d77213130e4b3e594115c028b708e7e.

In addition, we shouldn't print unknown error in case of known errors.
Moreover, in case of warnings/info, we shouldn't return -EIO that will

When trying to debug program, the user often needs to
dump large parts of the device's DRAM, which can reach to tens of GBs.
Because reading from the device's internal memory through the PCI BAR
is extremely slow, the debug can take hours.
Instead, we can provide the user to copy data through one of the DMA
engines. This will make the operation much faster.
Currently, only GAUDI is supported.
In GAUDI, we need to find a PCI DMA engine that is IDLE and set the
DMA as secured to be able to bypass our MMU as we currently don't
map the temporary buffer to the MMU.
Example bash one-line to dump entire HBM to file (~2 minutes):
for (( i=0x0; i < 0x800000000; i+=0x8000000 )); do \
printf '0x%x\n' $i | sudo tee /sys/kernel/debug/habanalabs/hl0/addr ; \
echo 0x8000000 | sudo tee /sys/kernel/debug/habanalabs/hl0/dma_size ; \
sudo cat /sys/kernel/debug/habanalabs/hl0/data_dma >> hbm.txt ; done

Since we moved the SOB reset flow to workqueue and
not part of the fence release flow, we might reach a
scenario where new context is created while we in the middle
of resetting the SOB.
in such cases the reset may fail due to idle check.
This will mess up the streams sync since the SOB value is invalid.
so we protect this area with a mutex, to delay context creation.
