The default i8259 polling function (i8259_irq) is nicely generic but is
fairly costly. Platforms often provide an alternative means of polling
for an i8259 interrupt, and when using the i8259 without device tree
have typically just chained its parent interrupt to their own handler
function. In order to allow for platform-specific polling functions to
be used in cases where the driver is probed via device tree, provide an
i8259_set_poll function that accepts a pointer to an alternative poll
function that will override the default.

Mapping the parent IRQ will use a virq number which may conflict with
the hardcoded I8259A_IRQ_BASE..I8259A_IRQ_BASE+15 range that the i8259
driver expects to be free. If this occurs then we'll hit errors when
adding the i8259 IRQ domain, since one of its virq numbers will already
be in use.
Avoid this by adding the i8259 domain before mapping the parent IRQ,
such that the i8259 virq numbers become used before the parent interrupt
controller gets a chance to use any of them.

Add a driver for simple ASCII LCD displays found on the MIPS Boston,
Malta & SEAD3 development boards. The Boston display is an independent
memory mapped device with a simple memory mapped 8 byte register space
containing the 8 ASCII characters to display. The Malta display is
exposed as part of the Malta board registers, and provides 8 registers
each of which corresponds to one of the ASCII characters to display. The
SEAD3 display is slightly more complex, exposing an interface to an
S6A0069 LCD controller via registers provided by the boards CPLD.
However although the displays differ in their register interface, we
require similar functionality on each board so abstracting away the
differences within a single driver allows us to share a significant
amount of code & ensure consistent behaviour.
The driver displays the Linux kernel version as the default message, but
allows the message to be changed via a character device. Messages longer
then the number of characters that the display can show will scroll.
This provides different behaviour to the existing LCD display code for
the MIPS Malta or MIPS SEAD3 platforms in the following ways:
- The default string to display is not "LINUX ON MALTA" or "LINUX ON
SEAD3" but "Linux" followed by the version number of the kernel
(UTS_RELEASE).
- Since that string tends to be significantly longer it scrolls twice
as fast, moving every 500ms rather than every 1s.
- The LCD won't be updated until the driver is probed, so it doesn't
provide the early "LINUX" string.

they are mandatory when using the Common Clock Framework.

While the driver is probing the adapter, an error may occur before the
netdev structure is allocated and attached to pci_dev. In this case,
not only netdev isn't available, but the tg3 private structure is also
not available as it is just math from the NULL pointer, so dereferences
must be skipped.
The following trace is seen when the error is triggered:

Pull libnvdimm fixes from Dan Williams:
- Four fixes for "flush hint" support.
Flush hints are addresses advertised by the ACPI 6+ NFIT (NVDIMM
Firmware Interface Table) that when written and fenced guarantee that
writes pending in platform write buffers (outside the cpu) have been
flushed to media. They might also be used by hypervisors as a
trigger condition to flush guest-persistent memory ranges to storage.
Fix a potential data corruption issue, a broken definition of the
hint array, a wrong allocation size for the unit test implementation
of the flush hint table, and missing NULL check in an error path.
The unit test, while it did not prevent these bugs from being
merged, at least triggered occasional crashes in advance of
production usages.
- Fix handling of ACPI DSM error status results. The DSM mechanism
allows communication with platform and memory device firmware. We
correctly parse known errors, but were silently ignoring others.
Fix it to consistently fail any command with a non-zero status return
that we otherwise do not interpret / handle.

This reverts commit 62469c76007e ("net: ethernet: bcmgenet: use phydev
from struct net_device") because it causes GENETv1/2/3 adapters to
expose the following behavior after an ifconfig down/up sequence:
PING fainelli-linux (10.112.156.244): 56 data bytes
64 bytes from 10.112.156.244: seq=1 ttl=61 time=1.352 ms

64 bytes from 10.112.156.244: seq=1 ttl=61 time=752.448 ms (DUP!)
This was previously fixed by commit 5dbebbb44a6a ("net: bcmgenet:
Software reset EPHY after power on") but the commit we are reverting was
essentially making this previous commit void, here is why.
Without commit 62469c76007e we would have the following scenario after
an ifconfig down then up sequence:
- bcmgenet_open() calls bcmgenet_power_up() to make sure the PHY is
initialized *before* we get to initialize the UniMAC, this is
critical to ensure the PHY is in a correct state, priv->phydev is
valid, this code executes fine
- second time from bcmgenet_mii_probe(), through the normal
phy_init_hw() call (which arguably could be optimized out)
Everything is fine in that case. With commit 62469c76007e, we would have
the following scenario to happen after an ifconfig down then up
sequence:
- bcmgenet_close() calls phy_disonnect() which makes dev->phydev become
NULL
- when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from
bcmgenet_power_up() to initialize the internal PHY, the NULL check
becomes true, so we do not reset the PHY, yet we keep going on and
initialize the UniMAC, causing MAC activity to occur
- we call bcmgenet_mii_reset() from bcmgenet_mii_probe(), but this is
too late, the PHY is botched, and causes the above bogus pings/packets
transmission/reception to occur

There are joystick devices that do not have those axes, for example TRC
Rudder device. The device in question has ABS_Z, ABS_RX and ABS_RY axes
causing it not being detected as joystick.
This patch adds ABS_Z to the input_device_id list allowing devices with

Pull irq fixes from Thomas Gleixner:
"Three fixes for irq core and irq chip drivers:
- Do not set the irq type if type is NONE. Fixes a boot regression
on various SoCs
- Use the proper cpu for setting up the GIC target list. Discovered
by the cpumask debugging code.
- A rather large fix for the MIPS-GIC so per cpu local interrupts
work again. This was discovered late because the code falls back
to slower timers which use normal device interrupts"

The definition of the flush hint table as:
void __iomem *flush_wpq[0][0];
...passed the unit test, but is broken as flush_wpq[0][1] and
flush_wpq[1][0] refer to the same entry. Fix this to use a helper that
calculates a slot in the table based on the geometry of flush hints in
the region. This is important to get right since virtualization
solutions use this mechanism to trigger hypervisor flushes to platform
persistence.

Commit 815806e39bf6 ("regmap: drop cache if the bus transfer error")
added a call to regcache_drop_region() to error path in
_regmap_raw_write(). However that path runs with regmap lock taken,
and regcache_drop_region() tries to re-take it, causing a deadlock.
Fix that by calling map->cache_ops->drop() directly.

A timer was used to restart after the bus-off state, leading to a
relatively large can_restart() executed in an interrupt context,
which in turn sets up pinctrl. When this happens during system boot,
there is a high probability of grabbing the pinctrl_list_mutex,
which is locked already by the probe() of other device, making the
kernel suspect a deadlock condition [1].
To resolve this issue, the restart_timer is replaced by a delayed
work.
