usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.

Commit e5dadc65f9e0 ("ppp: Fix false xmit recursion detect with two ppp
devices") dropped the xmit_recursion counter incrementation in
ppp_channel_push() and relied on ppp_xmit_process() for this task.
But __ppp_channel_push() can also send packets directly (using the
.start_xmit() channel callback), in which case the xmit_recursion
counter isn't incremented anymore. If such packets get routed back to
the parent ppp unit, ppp_xmit_process() won't notice the recursion and
will call ppp_channel_push() on the same channel, effectively creating
the deadlock situation that the xmit_recursion mechanism was supposed
to prevent.
This patch re-introduces the xmit_recursion counter incrementation in
ppp_channel_push(). Since the xmit_recursion variable is now part of
the parent ppp unit, incrementation is skipped if the channel doesn't
have any. This is fine because only packets routed through the parent
unit may enter the channel recursively.
Finally, we have to ensure that pch->ppp is not going to be modified
while executing ppp_channel_push(). Instead of taking this lock only
while calling ppp_xmit_process(), we now have to hold it for the full
ppp_channel_push() execution. This respects the ppp locks ordering
which requires locking ->upl before ->downl.

Go back to switching datapath directly in the notifier callback.
Otherwise datapath might not get switched on unregister.
No need for calling the NOTIFY_PEERS notifier since that is only for
a gratitious ARP/ND packet; but that is not required with Hyper-V
because both VF and synthetic NIC have the same MAC address.

The PF driver assumes the VF will not send another mailbox message until
the PF has written its reply to the previous message. If the VF does,
that message will be silently dropped by the PF before it writes its
reply to the mailbox. This results in a VF mailbox timeout for posted
messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.
Add a lock around the VF mailbox ops to prevent the VF from sending
another message while the PF is still processing the previous one.

When the PF receives a mailbox message from the VF, it grabs the mailbox
lock, reads the VF message from the mailbox, ACKs the message and drops
the lock.
While the PF is performing the action for the VF message, nothing
prevents another VF message from being posted to the mailbox. The
current code handles this condition by just dropping any new VF messages
without processing them. This results in a mailbox timeout in the VM
for posted messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.
Given the right sequence of VF messages and mailbox timeouts, this
condition can go on ad infinitum.
Modify the PF mailbox read method to take an 'unlock' argument that
optionally leaves the mailbox locked by the PF after reading the VF
message. This ensures another VF message is not posted to the mailbox
until after the PF has completed processing the VF message and written
its reply.

Unifies adjusted and unadjusted register value types (e.g. FRAME_POINTER is
now just a PTR_TO_STACK with zero offset).
Tracks value alignment by means of tracking known & unknown bits. This
also replaces the 'reg->imm' (leading zero bits) calculations for (what
were) UNKNOWN_VALUEs.
If pointer leaks are allowed, and adjust_ptr_min_max_vals returns -EACCES,
treat the pointer as an unknown scalar and try again, because we might be
able to conclude something about the result (e.g. pointer & 0x40 is either
0 or 0x40).

TSAUXC.DisableSystime is never set, so SYSTIM runs into a SYS WRAP
every 1100 secs on 80580/i350/i354 (40 bit SYSTIM) and every 35000
secs on 80576 (45 bit SYSTIM).
This wrap event sets the TSICR.SysWrap bit unconditionally.
However, checking TSIM at interrupt time shows that this event does not
actually cause the interrupt. Rather, it's just bycatch while the
actual interrupt is caused by, for instance, TSICR.TXTS.
The conclusion is that the SYS WRAP is actually expected, so the
"unexpected SYS WRAP" message is entirely bogus and just helps to
confuse users. Drop it.

HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the igb
driver still allowed TX packets to request HW timestamping. In this
situation, the _IGB_PTP_TX_IN_PROGRESS flag was set and would never
clear. This prevented any future HW timestamping requests to succeed.
Fix this by checking that the NIC is configured for HW TX timestamping
before accepting a HW TX timestamping request.

After add an ethertype filter, if user change the adapter speed several
times, the error "ethtool -N: etype filters are all used" is reported by
igb driver.
In older patch, function igb_nfc_filter_exit() and igb_nfc_filter_restore()
is not paried. igb_nfc_filter_restore() exist in igb_up(), but function
igb_nfc_filter_exit() is exist in __igb_close(). In the process of speed
changing, only igb_nfc_filter_restore() is called, it will take a position
of ethertype bitmap.
Reproduce steps:
Step 1: Add a etype filter by ethtool
$ethtool -N eth0 flow-type ether proto 0x88F8 action 1
Step 2: Change the adapter speed to 100M/full duplex
$ethtool -s eth0 speed 100 duplex full
Step 3: Change the adapter speed to 1000M/full duplex
ethtool -s eth0 speed 1000 duplex full
Repeat step2 and step3, then dmesg the system log, you can find the error
message, add new ethtype filter is also failed.
This fixing is move igb_nfc_filter_exit() from __igb_close() to igb_down()
to make igb_nfc_filter_restore()/igb_nfc_filter_exit() is paired.

Pull SCSI fixes from James Bottomley:
"Two small fixes, one re-fix of a previous fix and five patches sorting
out hotplug in the bnx2X class of drivers. The latter is rather
involved, but necessary because these drivers have started dropping
lockdep recursion warnings on the hotplug lock because of its
conversion to a percpu rwsem"

Fix the warning message on the parisc and IA64 architectures to show the
correct function name of the caller by using %pS instead of %pF. The
message is printed with the value of _RET_IP_ which calls
__builtin_return_address(0) and as such returns the IP address caller
instead of pointer to a function descriptor of the caller.
The effect of this patch is visible on the parisc and ia64 architectures
only since those are the ones which use function descriptors while on
all others %pS and %pF will behave the same.

Pull MTD fixes from Brian Norris:
"I missed getting these out for rc4, but here are some MTD fixes.
Just NAND fixes (in both the core handling, and a few drivers). Notes
stolen from Boris:
Core fixes:
- fix data interface setup for ONFI NANDs that do not support the SET
FEATURES command
- fix a kernel doc header
- fix potential integer overflow when retrieving timing information
from the parameter page
- fix wrong OOB layout for small page NANDs
Driver fixes:
- fix potential division-by-zero bug
- fix backward compat with old atmel-nand DT bindings
- fix ->setup_data_interface() in the atmel NAND driver"

Add extack error messages for failure paths creating vrf devices. Once
extack support is added to iproute2, we go from the unhelpful:
$ ip li add foobar type vrf
RTNETLINK answers: Invalid argument
to:
$ ip li add foobar type vrf
Error: VRF table id is missing

We allocate 'p_info->mfw_mb_cur' and 'p_info->mfw_mb_shadow' but we check
'p_info->mfw_mb_addr' instead of 'p_info->mfw_mb_cur'.
'p_info->mfw_mb_addr' is never 0, because it is initiliazed a few lines
above in 'qed_load_mcp_offsets()'.
Update the test and check the result of the 2 'kzalloc()' instead.

>From all switchdev devices only DSA requires special FDB dump. This is due
to lack of ability for syncing the hardware learned FDBs with the bridge.
Due to this it is removed from switchdev and moved inside DSA.

This is done as a preparation before removing support for MDB dump from
DSA core. The MDBs are synced with the bridge and thus there is no
need for special dump operation support.

The prepare phase for FDB add is unneeded because most of DSA devices
can have failures during bus transactions (SPI, I2C, etc.), thus, the
prepare phase cannot guarantee success of the commit stage.
The support for learning FDB through notification chain, which will be
introduced in the following patches, will provide the ability to notify
back the bridge about successful offload.
