The whole point behind adding driver_deferred_probe_force_trigger() in
commit 716a7a2596 ("driver core: fw_devlink: Add support for batching
fwnode parsing") was to skip the check for driver_deferred_probe_enable.
Otherwise, it's identical to driver_deferred_probe_trigger().
Delete the check in driver_deferred_probe_force_trigger() so that
fw_devlink_pause() and fw_devlink_resume() can kick off deferred probe
as intended. Without doing this forced deferred probe trigger, some
platforms seem to be crashing during boot because they assume probe
order of devices.

The fw_devlink_pause() and fw_devlink_resume() APIs allow batching the
parsing of the device tree nodes when a lot of devices are added. This
will significantly cut down parsing time (as much a 1 second on some
systems). So, use them when adding devices for all the top level device
tree nodes in a system.

The amount of time spent parsing fwnodes of devices can become really
high if the devices are added in an non-ideal order. Worst case can be
O(N^2) when N devices are added. But this can be optimized to O(N) by
adding all the devices and then parsing all their fwnodes in one batch.
This commit adds fw_devlink_pause() and fw_devlink_resume() to allow
doing this.

Commit 4dbe191c04 ("driver core: Add device links from fwnode only for
the primary device") skipped linking a fwnode's secondary device to
the suppliers listed in its fwnode.
However, a fwnode's secondary device can't be found using
get_dev_from_fwnode(). So, there's no point in trying to see if devices
waiting for suppliers might want to link to a fwnode's secondary device.
This commit removes that unnecessary step for devices that aren't a
fwnode's primary device and also moves the code to a more appropriate
part of the file.

Sometimes, more than one (generally two) device can point to the same
fwnode. However, only one device is set as the fwnode's device
(fwnode->dev) and can be looked up from the fwnode.
Typically, only one of these devices actually have a driver and actually
probe. If we create device links for all these devices, then the
suppliers' of these devices (with the same fwnode) will never get a
sync_state() call because one of their consumer devices will never probe
(because they don't have a driver).
So, create device links only for the device that is considered as the
fwnode's device.
One such example of this is the PCI bridge platform_device and the
corresponding pci_bus device. Both these devices will have the same
fwnode. It's the platform_device that is registered first and is set as
the fwnode's device. Also the platform_device is the one that actually
probes. Without this patch none of the suppliers of a PCI bridge
platform_device would get a sync_state() callback.

[ Upstream commit 79dde73cf9 ]
ugeth_quiesce/activate are used to halt the controller when there is a
link change that requires to reconfigure the mac.
The previous implementation called netif_device_detach(). This however
causes the initial activation of the netdevice to fail precisely because
it's detached. For details, see [1].
A possible workaround was the revert of commit
net: linkwatch: add check for netdevice being present to linkwatch_do_dev
However, the check introduced in the above commit is correct and shall be
kept.
The netif_device_detach() is thus replaced with
netif_tx_stop_all_queues() that prevents any tranmission. This allows to
perform mac config change required by the link change, without detaching
the corresponding netdevice and thus not preventing its initial
activation.

[ Upstream commit ac8372f3b4 ]
On s390, the layout of normal and large ptes (i.e. pmds/puds) differs.
Therefore, set_huge_pte_at() does a conversion from a normal pte to
the corresponding large pmd/pud. So, when converting an empty pte, this
should result in an empty pmd/pud, which would return true for
pmd/pud_none().
However, after conversion we also mark the pmd/pud as large, and
therefore present. For empty ptes, this will result in an empty pmd/pud
that is also marked as large, and pmd/pud_none() would not return true.
There is currently no issue with this behaviour, as set_huge_pte_at()
does not seem to be called for empty ptes. It would be valid though, so
let's fix this by not marking empty ptes as large in set_huge_pte_at().
This was found by testing a patch from from Anshuman Khandual, which is
currently discussed on LKML ("mm/debug: Add more arch page table helper

stack_trace_save+0x50/0x68
stack_trace_call+0x15a/0x3b8

__do_execve_file.isra.0+0x7d8/0x860
__s390x_sys_execve+0x56/0x68
system_call+0xdc/0x2d8
Note random "0x3e0007e3c98" stack value as ftraced function caller. This
value causes either imprecise unwinder result or unwinding failure.
That "0x3e0007e3c98" comes from r14 of ftraced function stack frame, which
it haven't had a chance to initialize since the very first instruction
calls ftrace code ("ftrace_caller"). (ftraced function might never
save r14 as well). Nevertheless according to s390 ABI any function
is called with stack frame allocated for it and r14 contains return
address. "ftrace_caller" itself is called with "brasl %r0,ftrace_caller".
So, to fix this issue simply always save traced function caller onto
ftraced function stack frame.

commit 38152ea37d upstream.
Currently, setting a bridge's self PVID to other value and deleting
the default VID 1 renders untagged ports of that VLAN unable to talk to
the CPU port:
bridge vlan add dev br0 vid 2 pvid untagged self
bridge vlan del dev br0 vid 1 self
bridge vlan add dev sw0p0 vid 2 pvid untagged
bridge vlan del dev sw0p0 vid 1
# br0 cannot send untagged frames out of sw0p0 anymore
That is because the CPU port is set to security mode and its PVID is
still 1, and untagged frames are dropped due to VLAN member violation.
Set the CPU port to fallback mode so untagged frames can pass through.

Fix for non-working buttons on knock-off USB dongles for Sony
controllers. These USB dongles are used to connect older Sony DA/DS1/DS2
controllers via USB and are common on Amazon, AliExpress, etc. Without
the patch, the square, X, and circle buttons do not function. These
dongles used to work prior to kernel 4.10 but removing the global DS3
report fixup in commit e19a267b99 ("HID: sony: DS3 comply to Linux gamepad
spec") exposed the problem.
Many people reported the problem on the Ubuntu forums and are working
around the problem by falling back to the 4.9 hid-sony driver.
The problem stems from these dongles incorrectly reporting their button
count as 13 instead of 16. This patch fixes up the report descriptor by
changing the button report count to 16 and removing 3 padding bits.

[ Upstream commit d8ef4b38cb ]
This reverts commit 9a9e97b2f1 ("cgroup: Add memory barriers to plug
cgroup_rstat_updated() race window").
The commit was added in anticipation of memcg rstat conversion which needed
synchronous accounting for the event counters (e.g. oom kill count). However,
the conversion didn't get merged due to percpu memory overhead concern which
couldn't be addressed at the time.
Unfortunately, the patch's addition of smp_mb() to cgroup_rstat_updated()
meant that every scheduling event now had to go through an additional full
barrier and Mel Gorman noticed it as 1% regression in netperf UDP_STREAM test.
There's no need to have this barrier in tree now and even if we need
synchronous accounting in the future, the right thing to do is separating that
out to a separate function so that hot paths which don't care about
synchronous behavior don't have to pay the overhead of the full barrier. Let's
revert.

The ABI representation can now contain multiple anonymous data
structures embedded in a enclosing data structure. Hence update the
representation.

commit a068aab422 upstream.
kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object. Previous
commit "b8eb718348b8" fixed a similar problem.
Fixes: 07699f9a7c ("bonding: add sysfs /slave dir for bond slave devices.")
