drm/nouveau/fb: remove ram oclass argument from base fb constructor
Introduced a unfortunate regression by using nv10 ram oclass for nv1a
hardware, causing corruption and eventually system lockup.

We must use a 64-bit for this, otherwise overflowed bits get lost, and

Issuing set_termios() from irtty_close() causes kernel Oops for
unplugged usb-serial devices.
Since no other tty_ldisc calls set_termios() on close and no tty driver
seem to check if tty->device_data is NULL or not on entry to set_termios(),
the only solution I can come up with is to remove the irtty_stop_receiver()
call, which only updates termios.

aggregator_identifier is used to assign unique aggregator identifiers
to aggregators of a bond during device enslaving.
aggregator_identifier is currently a global variable that is zeroed in
bond_3ad_initialize().
This sequence will lead to duplicate aggregator identifiers for eth1 and eth3:
create bond0
change bond0 mode to 802.3ad
enslave eth0 to bond0 //eth0 gets agg id 1
enslave eth1 to bond0 //eth1 gets agg id 2
create bond1
change bond1 mode to 802.3ad
enslave eth2 to bond1 //aggregator_identifier is reset to 0
//eth2 gets agg id 1
enslave eth3 to bond0 //eth3 gets agg id 2
Fix this by making aggregator_identifier private to the bond.

This patch removes a generic hard_header_len check from the usbnet
module that is causing dropped packages under certain circumstances
for devices that send rx packets that cross urb boundaries.
One example is the AX88772B which occasionally send rx packets that
cross urb boundaries where the remaining partial packet is sent with
no hardware header. When the buffer with a partial packet is of less
number of octets than the value of hard_header_len the buffer is
discarded by the usbnet module.
With AX88772B this can be reproduced by using ping with a packet
size between 1965-1976.
The bug has been reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=29082
This patch introduces the following changes:
- Removes the generic hard_header_len check in the rx_complete
function in the usbnet module.
- Introduces a ETH_HLEN check for skbs that are not cloned from
within a rx_fixup callback.
- For safety a hard_header_len check is added to each rx_fixup
callback function that could be affected by this change.
These extra checks could possibly be removed by someone
who has the hardware to test.
- Removes a call to dev_kfree_skb_any() and instead utilizes the
dev->done list to queue skbs for cleanup.
The changes place full responsibility on the rx_fixup callback
functions that clone skbs to only pass valid skbs to the
usbnet_skb_return function.

Added STM sensor hub vendor id in HID_SENSOR_HUB_ENUM_QUIRK to
fix report descriptors. These devices uses old FW which uses
logical 0 as minimum. In these, HID reports are not using proper
collection classes. So we need to fix report descriptors,for
such devices. This will not have any impact, if the FW uses
logical 1 as minimum.
We look for usage id for "power and report state", and modify
logical minimum value to 1.
This is a follow-up patch to commit id 875e36f8.

Add a new argument for ndo_select_queue() callback that passes a
fallback handler. This gets invoked through netdev_pick_tx();
fallback handler is currently __netdev_pick_tx() as most drivers
invoke this function within their customized implementation in
case for skbs that don't need any special handling. This fallback
handler can then be replaced on other call-sites with different
queue selection methods (e.g. in packet sockets, pktgen etc).
This also has the nice side-effect that __netdev_pick_tx() is
then only invoked from netdev_pick_tx() and export of that
function to modules can be undone.

When an error occurs in the port initialization loop, currently the
driver tries to cleanup all the ports. This results in a NULL pointer
dereference if the ports were only partially initialized.
Fix this by updating only the number of initialized ports (either
with failure or successfully), before jumping to the error path
and looping over that number in the cleanup loop.

Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.
To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.
Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

Because the offload mechanism can fall back to a standard transfer,
having two seperate initialization states is unfortunate. Let's just
have one state which does things consistently. This fixes a bug where
some preparation was missing when the fallback happened. And it makes
the code much easier to follow. To implement this, we put the check
if offload is possible at the top of the offload setup function.

Commit 8fdade4 ("net: of_mdio: parse "max-speed" property to set PHY
supported features") introduced a typo in of_set_phy_supported for the
first assignment of phydev->supported which will not effectively limit
the PHY device supported features bits if the PHY driver contains
"higher" features (e.g: max-speed = <100> and PHY driver has
PHY_GBIT_FEATURES set).
Fix this by making sure that the very first thing is to reset to sane
defaults (PHY_BASIC_FEATURES) and then progressively add speed features
as we parse them.

Pull ACPI and power management fixes from Rafael Wysocki:
"These include a fix for a recent intel_pstate regression, a fix for a
regression in the ACPI-based PCI hotplug (ACPIPHP) code introduced
during the 3.12 cycle, fixes for two bugs in the ACPI core introduced
recently and a MAINTAINERS update related to cpufreq.
Specifics:
- Fix for a recent regression in the intel_pstate driver that
introduced a race condition causing systems to crash during
initialization in some situations. This removes the affected code
altogether. From Dirk Brandewie.
- ACPIPHP fix for a regression introduced during the 3.12 cycle
causing devices to be dropped as a result of bus check
notifications after system resume on some systems due to the way
ACPIPHP interprets _STA return values (arguably incorrectly). From
Mika Westerberg.
- ACPI dock driver fix for a problem causing docking to fail due to a
check that always fails after recent ACPI core changes (found by
code inspection).
- ACPI container driver fix to prevent memory from being leaked in an
error code path after device_register() failures.
- Update of the arm_big_little cpufreq driver maintainer's e-mail
address"

Pull EDAC fixes from Borislav Petkov:
"Fix polling timeout setting through sysfs.
You're surely wondering why the patches are not based on an rc. Well,
Andrew sent you 79040cad3f82 ("drivers/edac/edac_mc_sysfs.c: poll
timeout cannot be zero sent you") already (it got in in -rc2) but it
is not enough as a fix because for one, setting too low polling
intervals (< 1sec) don't make any sense and cause unnecessary polling
load on the system.
Then, even if we set some interval, we explode with
[ 4143.094342] WARNING: CPU: 1 PID: 0 at kernel/workqueue.c:1393 __queue_work+0x1d7/0x340()
because the workqueue setup path is used also for the timeout period
resetting and we're doing INIT_DELAYED_WORK() on an already active
workqueue. Which is total bollocks. So this is taken care of by the
second patch.
I've CCed stable for those two"
