Pull smb3 fix from Steve French:
"An important smb3 fix for an regression to some servers introduced by
compounding optimization to rmdir.
This fix has been tested by multiple developers (including me) with
the usual private xfstesting, but also by the new cifs/smb3 "buildbot"
xfstest VMs (thank you Ronnie and Aurelien for good work on this
automation). The automated testing has been updated so that it will
catch problems like this in the future.
Note that Pavel discovered (very recently) some unrelated but
extremely important bugs in credit handling (smb3 flow control problem
that can lead to disconnects/reconnects) when compounding, that I
would have liked to send in ASAP but the complete testing of those two
fixes may not be done in time and have to wait for 4.21"

dmesg reports that "Your touchpad (PNP: SYN3052 SYN0100 SYN0002 PNP0f13)

I've tested the offered psmouse.synaptics_intertouch=1 with 4.18.x and
4.19.x and it seems to work well. No problems seen with suspend/resume.
Also, it appears that RMI/SMBus mode is actually required for 3-4 finger

The current implementation of elan_i2c is known to not support those
2 laptops.
A proper fix is to tweak both elantech and elan_i2c to transmit the
correct information from PS/2, which would make a bad candidate for
stable.
So to give us some time for fixing the root of the problem, disable
elan_i2c for the devices we know are not behaving properly.

The gpio IP on Armada 370 at offset 0x18180 has neither a clk nor pwm
registers. So there is no need for a clk as the pwm isn't used anyhow.
So only check for the clk in the presence of the pwm registers. This fixes
a failure to probe the gpio driver for the above mentioned gpio device.

Commit ec0daae685 ("gpio: omap: Add level wakeup handling for omap4
based SoCs") attempted to fix omap4 GPIO wakeup handling as it was
blocking deeper SoC idle states. However this caused a regression for
GPIOs during runtime having over second long latencies for Ethernet
GPIO interrupt as reportedy by Russell King <rmk+kernel@armlinux.org.uk>.
Let's fix this issue by doing a partial revert of the breaking commit.
We still want to keep the quirk handling around as it is also used for
OMAP_GPIO_QUIRK_IDLE_REMOVE_TRIGGER.
The real fix for omap4 GPIO wakeup handling involves fixes for
omap_set_gpio_trigger() and omap_gpio_unmask_irq() and will be posted
separately. And we must keep the wakeup bit enabled during runtime
because of module doing clock autogating with autoidle configured.

Disabling lock debugging due to kernel taint
....
The failures are from anyway that frees pages and empties the
per-cpu page magazines, so it's not a predictable failure or an easy
to debug failure.
generic/038 is a reliable reproducer of this problem - it has a 9 in
10 failure rate on one of my test machines. Failure on other
machines have been at random points in fstests runs but every run
has ended up tripping this problem. Hence generic/038 was used to
bisect the failure because it was the most reliable failure.
It is too close to the 4.20 release (not to mention holidays) to
try to diagnose, fix and test the underlying cause of the problem,
so reverting the commit is the only option we have right now. The
revert has been tested against a current tot 4.20-rc7+ kernel across
multiple machines running sub-page block size XFs filesystems and
none of the bad page state failures have been seen.

It is reported that commit 95f408bbc4 ("media: cx23885: Ryzen DMA

Ensure that the quirk will be applied only for the CPUs that
are known to cause problems.
A module option is added for explicit control of the behaviour.

Doing a survey of the kernel tree, this appears to be expected because
'#include <asm/irq.h>' is always after the linux includes.
This also fixes warnings of this variety (with Clang):

Remove PCI dependent code out of iort.c when CONFIG_PCI is not defined.
A quick search reveals the following functions:
1. pci_request_acs()
2. pci_domain_nr()
3. pci_is_root_bus()
4. to_pci_dev()
Both pci_domain_nr() and pci_is_root_bus() are defined in linux/pci.h.
pci_domain_nr() is a stub function when CONFIG_PCI is not set and
pci_is_root_bus() just returns a reference to a structure member which
is still valid without CONFIG_PCI set.
to_pci_dev() is a macro that expands to container_of.
pci_request_acs() is the only code that gets pulled in from drivers/pci/*.c

nr is indirectly controlled by user-space, hence leading to a
potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/gpu/drm/drm_ioctl.c:805 drm_ioctl() warn: potential spectre issue 'dev->driver->ioctls' [r]
drivers/gpu/drm/drm_ioctl.c:810 drm_ioctl() warn: potential spectre issue 'drm_ioctls' [r] (local cap)
drivers/gpu/drm/drm_ioctl.c:892 drm_ioctl_flags() warn: potential spectre issue 'drm_ioctls' [r] (local cap)
Fix this by sanitizing nr before using it to index dev->driver->ioctls
and drm_ioctls.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].
