A new user flag is required to make memory map hint mandatory, in
contrast to the current situation where it is best effort.
This is due to the requirement to map certain data to specific

Add support for pre-determined driver-reserved device VA address ranges.
This is needed for future ASIC support where some contents must be
mapped into these pre-determined ranges because the H/W will be
configured using these ranges.
In case the user asks to map a VA without a hint address, avoid
allocating the device VA from the reserved ranges.
Make sure the validation checks of the hint address take into account
situation where the DRAM page size is not pow of 2.

The SD/OE pin may be configured to enable output when high or low, and
to shutdown the device when high. This behavior is controller by the SH
and SP bits of the Primary Source and Shutdown Register (and to a lesser
extent the OS and OE bits). By default, both bits are 0 (unless set by
OTP memory), but they may need to be configured differently, depending
on the external circuitry controlling the SD/OE pin.

'clk_init_data' for gates is setting up 'CLK_IS_CRITICAL'
flag for all of them. This was being doing because some
drivers of this SoC might not be ready to use the clock
and we don't wanted the kernel to disable them since default
behaviour without clock driver was to set all gate bits to
enabled state. After a bit more testing and checking driver
code it is safe to remove this flag and just let the kernel
to disable those gates that are not in use. No regressions
seems to appear.

This driver exposes hardware sensors of the Aquacomputer D5 Next
watercooling pump, which communicates through a proprietary USB HID
protocol.
Available sensors are pump and fan speed, power, voltage and current, as
well as coolant temperature. Also available through debugfs are the serial
number, firmware version and power-on count.
Attaching a fan is optional and allows it to be controlled using
temperature curves directly from the pump. If it's not connected,
the fan-related sensors will report zeroes.
The pump can be configured either through software or via its physical
interface. Configuring the pump through this driver is not implemented,
as it seems to require sending it a complete configuration. That
includes addressable RGB LEDs, for which there is no standard sysfs
interface. Thus, that task is better suited for userspace tools.
This driver has been tested on x86_64, both in-kernel and as a module.

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.

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 functions get_online_cpus() and put_online_cpus() have been
deprecated during the CPU hotplug rework. They map directly to
cpus_read_lock() and cpus_read_unlock().
Replace deprecated CPU-hotplug functions with the official version.
The behavior remains unchanged.

Pull block fixes from Jens Axboe:
- Revert the mq-deadline priority handling, it's causing serious
performance regressions. While experimental patches exists to fix
this up, it's too late to do so now. Revert it and re-do it properly
for 5.15 instead.
- Fix a NULL vs IS_ERR() regression in this release (Dan)
- Fix a mq-deadline accounting regression in this release (Bart)
- Mark cryptoloop as deprecated. It's broken and dm-crypt fully
supports it, and it's actively intefering with loop. Plan on removal
for 5.16 (Christoph)

We can't split write behind bio with more than BIO_MAX_VECS sectors,
