In some cases of fw_down it was called because there was a
fw_generation change, and the firmware is already back up.
In order to keep the down time to a minimum, don't wait for
the next watchdog polling cycle, fire another watchdog off
as soon as we can - an out-of-cycle check won't hurt, and
may well speed up the recovery.

The patch breaks userspace implementations (e.g. fdutils) and introduces
regressions in behaviour. Previously, it was possible to O_NDELAY open a
floppy device with no media inserted or with write protected media without
an error. Some userspace tools use this particular behavior for probing.
It's not the first time when we revert this patch. Previous revert is in
commit f2791e7eadf4 (Revert "floppy: refactor open() flags handling").
This reverts commit 8a0c014cd20516ade9654fc13b51345ec58e7be8.

Add entry for CFG80211 to reflect that it is currently being worked on
and is a desirable feature to have for this driver. Leave entries for
LIB80211 and MAC80211 in case anyone else wishes to work on them - they
can always be removed later, but MAC80211 in particular would certainly
be good to aim for. Also, include an entry for improving error handling,

The kernel provides a "/proc/sys/net/ipv6/conf/<iface>/mtu"
file, which can temporarily record the mtu value of the last
received RA message when the RA mtu value is lower than the
interface mtu, but this proc has following limitations:
(1) when the interface mtu (/sys/class/net/<iface>/mtu) is
updeated, mtu6 (/proc/sys/net/ipv6/conf/<iface>/mtu) will
be updated to the value of interface mtu;
(2) mtu6 (/proc/sys/net/ipv6/conf/<iface>/mtu) only affect
ipv6 connection, and not affect ipv4.
Therefore, when the mtu option is carried in the RA message,
there will be a problem that the user sometimes cannot obtain
RA mtu value correctly by reading mtu6.
After this patch set, if a RA message carries the mtu option,
you can send a netlink msg which nlmsg_type is RTM_GETLINK,
and then by parsing the attribute of IFLA_INET6_RA_MTU to
get the mtu value carried in the RA message received on the
inet6 device. In addition, you can also get a link notification
when ra_mtu is updated so it doesn't have to poll.
In this way, if the MTU values that the device receives from
the network in the PCO IPv4 and the RA IPv6 procedures are
different, the user can obtain the correct ipv6 ra_mtu value
and compare the value of ra_mtu and ipv4 mtu, then the device
can use the lower MTU value for both IPv4 and IPv6.

driver probe list
Enabling interrupts via device tree for the internal PHYs on the
mv88e6390 DSA switch does not work. The driver insists to use poll mode.
Stage one debugging shows that the fwnode_mdiobus_phy_device_register
function calls fwnode_irq_get properly, and phy->irq is set to a valid
interrupt line initially.
But it is then cleared.
Stage two debugging shows that it is cleared here:
phy_probe:
/* Disable the interrupt if the PHY doesn't support it
* but the interrupt is still a valid one
*/
if (!phy_drv_supports_irq(phydrv) && phy_interrupt_is_valid(phydev))
phydev->irq = PHY_POLL;
Okay, so does the "Marvell 88E6390 Family" PHY driver not have the
.config_intr and .handle_interrupt function pointers? Yes it does.
Stage three debugging shows that the PHY device does not attempt a probe
against the "Marvell 88E6390 Family" driver, but against the "mv88x3310"
driver.
Okay, so why does the "mv88x3310" driver match on a mv88x6390 internal
PHY? The PHY IDs (MARVELL_PHY_ID_88E6390_FAMILY vs
MARVELL_PHY_ID_88X3310) are way different.
Stage four debugging has us looking through:
phy_device_register
-> device_add
-> bus_probe_device
-> device_initial_probe
-> __device_attach
-> bus_for_each_drv
-> driver_match_device
-> drv->bus->match
-> phy_bus_match
Okay, so as we said, the MII_PHYSID1 of mv88e6390 does not match the
mv88x3310 driver's PHY mask & ID, so why would phy_bus_match return...
Ahh, phy_bus_match calls a shortcircuit method,
phydrv->match_phy_device, and does not even bother to compare the PHY ID
if that is implemented.
So of course, we go inside the marvell10g.c driver and sure enough, it
implements .match_phy_device and does not bother to check the PHY ID.
What's interesting though is that at the end of the device_add() from
phy_device_register(), the driver for the internal PHYs _is_ the proper
"Marvell 88E6390 Family". This is because "mv88x3310" ends up failing to
probe after all, and __device_attach_driver(), to quote:
/*
* Ignore errors returned by ->probe so that the next driver can try
* its luck.
*/
The next (and only other) driver that matches is the 6390 driver. For
this one, phy_probe doesn't fail, and everything expects to work as
normal, EXCEPT phydev->irq has already been cleared by the previous
unsuccessful probe of a driver which did not implement PHY interrupts,
and therefore cleared that IRQ.
Okay, so it is not just Marvell 6390 that has PHY interrupts broken.
Stuff like Atheros, Aquantia, Broadcom, Qualcomm work because they are
lexicographically before Marvell, and stuff like NXP, Realtek, Vitesse
are broken.
This goes to show how fragile it is to reset phydev->irq = PHY_POLL from
the actual beginning of phy_probe itself. That seems like an actual bug
of its own too, since phy_probe has side effects which are not restored
on probe failure, but the line of thought probably was, the same driver
will attempt probe again, so it doesn't matter. Well, looks like it
does.
Maybe it would make more sense to move the phydev->irq clearing after
the actual device_add() in phy_device_register() completes, and the
bound driver is the actual final one.
(also, a bit frightening that drivers are permitted to bypass the MDIO
bus matching in such a trivial way and perform PHY reads and writes from
the .match_phy_device method, on devices that do not even belong to
them. In the general case it might not be guaranteed that the MDIO
accesses one driver needs to make to figure out whether to match on a
device is safe for all other PHY devices)

bnxt may discard packets if Rx completions are consumed
in an attempt to let netpoll make progress. It should be
extremely rare in practice but nonetheless such events
should be counted.
Since completion ring memory is allocated dynamically use
a similar scheme to what is done for HW stats to save them.
Report the stats in rx_dropped and per-netdev ethtool
counter. Chances that users care which ring dropped are
very low.
v3: only save the stat to rx_dropped on reset,
rx_total_netpoll_discards will now only show drops since
last reset, similar to other "total_discard" counters.

The recursion protection for eventfd_signal() is based on a per CPU
variable and relies on the !RT semantics of spin_lock_irqsave() for
protecting this per CPU variable. On RT kernels spin_lock_irqsave() neither
disables preemption nor interrupts which allows the spin lock held section
to be preempted. If the preempting task invokes eventfd_signal() as well,
then the recursion warning triggers.
Paolo suggested to protect the per CPU variable with a local lock, but
that's heavyweight and actually not necessary. The goal of this protection
is to prevent the task stack from overflowing, which can be achieved with a
per task recursion protection as well.
Replace the per CPU variable with a per task bit similar to other recursion
protection bits like task_struct::in_page_owner. This works on both !RT and
RT kernels and removes as a side effect the extra per CPU storage.
No functional change for !RT kernels.

commit 3ba7f53f8bf1 ("ice: don't remove netdev->dev_addr from uc sync
list") introduced calls to netif_addr_lock_bh() and
netif_addr_unlock_bh() in the driver's ndo_set_mac() callback. This is
fine since the driver is updated the netdev's dev_addr, but since this
is a spinlock, the driver cannot sleep when the lock is held.
Unfortunately the functions to add/delete MAC filters depend on a mutex.
This was causing a trace with the lock debug kernel config options
enabled when changing the mac address via iproute.

Fix this by only locking when changing the netdev->dev_addr. Also, make
sure to restore the old netdev->dev_addr on any failures.

When we enabled auxiliary input/output support for the E810 device, we
forgot to add logic to restart the output when we change time. This is
important as the periodic output will be incorrect after a time change
otherwise.
This unfortunately includes the adjust time function, even though it
uses an atomic hardware interface. The atomic adjustment can still cause
the pin output to stall permanently, so we need to stop and restart it.
Introduce wrapper functions to temporarily disable and then re-enable
the clock outputs.

This reverts commit 0092a1e3f7636ff4e202a41b0320690699247e22
This should be reverted in the char-misc-next branch to make merging
with Linus's branch possible due to issues with the mhi code that was
found in the networking tree.

This seems to be a false alarm because hex_attr size is always smaller
than n->length. This patch fix this warning by allocation hex_attr with

If CONFIG_PM_OPP=n, of_get_required_opp_performance_state() always
returns -EOPNOTSUPP, and all drivers for devices that are part of a PM
Domain fail to probe with:
failed to set required performance state for power-domain foo: -95
probe of bar failed with error -95
Fix this by treating -EOPNOTSUPP the same as -ENODEV.

in favor of dm-crypt (which supports the same broken algorithms if
needed) in Linux 2.6.4 (released in March 2004), and support for it has
been entirely removed from losetup in util-linux 2.23 (released in April
2013). Add a warning and a deprecation schedule.
