[ Upstream commit 8f110f530635af44fff1f4ee100ecef0bac62510 ]
Due to the audit control mutex necessary for serializing audit
userspace messages we haven't been able to block/penalize userspace
processes that attempt to send audit records while the system is
under audit pressure. The result is that privileged userspace
applications have a priority boost with respect to audit as they are
not bound by the same audit queue throttling as the other tasks on
the system.
This patch attempts to restore some balance to the system when under
audit pressure by blocking these privileged userspace tasks after
they have finished their audit processing, and dropped the audit
control mutex, but before they return to userspace.

[ Upstream commit 8c3e5b74b9e2146f564905e50ca716591c76d4f1 ]
The mmc core takes a specific path to support initializing of a
non-standard SDIO card. This is triggered by looking for the card-quirk,
MMC_QUIRK_NONSTD_SDIO.
In mmc_sdio_init_card() this gets rather messy, as it causes the code to
bail out earlier, compared to the usual path. This leads to that the OCR
doesn't get saved properly in card->ocr. Fortunately, only omap_hsmmc has
been using the MMC_QUIRK_NONSTD_SDIO and is dealing with the issue, by
assigning a hardcoded value (0x80) to card->ocr from an ->init_card() ops.
To make the behaviour consistent, let's instead rely on the core to save
the OCR in card->ocr during initialization.

The PHY settings table is supposed to be sorted by descending match
priority - in other words, earlier entries are preferred over later
entries.
The order of 1000baseKX/Full and 1000baseT/Full is such that we
prefer 1000baseKX/Full over 1000baseT/Full, but 1000baseKX/Full is
a lot rarer than 1000baseT/Full, and thus is much less likely to
be preferred.
This causes phylink problems - it means a fixed link specifying a
speed of 1G and full duplex gets an ethtool linkmode of 1000baseKX/Full
rather than 1000baseT/Full as would be expected - and since we offer
userspace a software emulation of a conventional copper PHY, we want
to offer copper modes in preference to anything else. However, we do
still want to allow the rarer modes as well.
Hence, let's reorder these two modes to prefer copper.

If userspace installs a lot of multicast groups very quickly, then
we may run out of command queue space as we send the updates in an
asynchronous fashion (due to locking concerns), and the CPU can
create them faster than the firmware can process them. This is true
even when mac80211 has a work struct that gets scheduled.
Fix this by synchronizing with the firmware after sending all those
commands - outside of the iteration we can send a synchronous echo
command that just has the effect of the CPU waiting for the prior
asynchronous commands to finish. This also will cause fewer of the
commands to be sent to the firmware overall, because the work will
only run once when rescheduled multiple times while it's running.

If protocol tunnels are already up when the driver is loaded, for
instance if the boot firmware implements connection manager of its own,
runtime PM reference count of the consumer devices behind the tunnel
might have been increased already before the device link is created but
the supplier device runtime PM reference count is not. This leads to a
situation where the supplier (the Thunderbolt driver) can runtime
suspend even if it should not because the corresponding protocol tunnel
needs to be up causing the devices to be removed from the corresponding
native bus.
Prevent this from happening by making both sides of the link runtime PM
active briefly. The pm_runtime_put() for the consumer (PCIe
root/downstream port, xHCI) then allows it to runtime suspend again but
keeps the supplier runtime resumed the whole time it is runtime active.

- The minimum width and height supported is 5x2, not 2x4, this is an
artifact from the driver's soc-camera days. Fix this incorrect
assumption.

Some uvc devices appear to require the maximum allowed USB timeout
for GET_CUR/SET_CUR requests.
So lets just bump the UVC control timeout to 5 seconds which is the
same as the usb ctrl get/set defaults:
USB_CTRL_GET_TIMEOUT 5000
USB_CTRL_SET_TIMEOUT 5000
It fixes the following runtime warnings:
Failed to query (GET_CUR) UVC control 11 on unit 2: -110 (exp. 1).
Failed to query (SET_CUR) UVC control 3 on unit 2: -110 (exp. 2).

When the CMM is enabled, an offset of 25 pixels must be subtracted from
the HDS (horizontal display start) and HDE (horizontal display end)
registers. Fix the timings calculation, and take this into account in
the mode validation.
This fixes a visible horizontal offset in the image with VGA monitors.
HDMI monitors seem to be generally more tolerant to incorrect timings,
but may be affected too.

Move the switching code into a function so that it can be re-used and
add a global TLB flush. This makes sure that usage of memory which is
not mapped in the trampoline page-table is reliably caught.
Also move the clearing of CR4.PCIDE before the CR3 switch because the
cr4_clear_bits() function will access data not mapped into the
trampoline page-table.

[ Upstream commit 57d2dbf710d832841872fb15ebb79429cab90fae ]
The GPD win and its sibling the GPD pocket (99% the same electronics in a
different case) use a PCI wifi card. But the ACPI tables on both variants
contain a bug where the SDIO MMC controller for SDIO wifi cards is enabled
despite this. This SDIO MMC controller has a PCI0.SDHB.BRC1 child-device
which _PS3 method sets a GPIO causing the PCI wifi card to turn off.
At the moment there is a pretty ugly kludge in the sdhci-acpi.c code,
just to work around the bug in the DSDT of this single design. This can
be solved cleaner/simply with a quirk overriding the _STA return of the
broken PCI0.SDHB.BRC1 PCI0.SDHB.BRC1 child with a status value of 0,
so that its power_manageable flag gets cleared, avoiding this problem.
Note that even though it is not used, the _STA method for the MMC
controller is deliberately not overridden. If the status of the MMC
controller were forced to 0 it would never get suspended, which would
cause these mini-laptops to not reach S0i3 level when suspended.

Not all ACPI-devices have a HID + UID, allow specifying quirks for
acpi_device_override_status() by path too.
Note this moves the path/HID+UID check to after the CPU + DMI checks
since the path lookup is somewhat costly.
This way this lookup is only done on devices where the other checks
match.

[ Upstream commit 1a68b346a2c9969c05e80a3b99a9ab160b5655c0 ]
Currently, acpi_bus_get_status() calls acpi_device_always_present() to
allow platform quirks to override the _STA return to report that a
device is present (status = ACPI_STA_DEFAULT) independent of the _STA
return.
In some cases it might also be useful to have the opposite functionality
and have a platform quirk which marks a device as not present (status = 0)
to work around ACPI table bugs.
Change acpi_device_always_present() into a more generic
acpi_device_override_status() function to allow this.

It turns out that there is a WMI object which controls the PWM2 device
used for the keyboard backlight and that WMI object also provides some
other useful functionality.
The upcoming lenovo-yogabook-wmi driver will offer both backlight
control and the other functionality, so there no longer is a need
to have the lpss-pwm driver binding to PWM2 for backlight control;
and this is now actually undesirable because this will cause both
the WMI code and the lpss-pwm driver to poke at the same PWM
controller.
Drop the always-present quirk for the PWM2 ACPI-device, so that the
lpss-pwm controller will no longer bind to it.

For larger (bigger than a page) and noncontiguous mobs we have
to create page tables that allow the host to find the memory.
Those page tables just used regular system memory. Unfortunately
in TTM those BO's are not allowed to be busy thus can't be
fenced and we have to fence those bo's because we don't want
to destroy the page tables while the host is still executing
the command buffers which might be accessing them.
To solve it we introduce a new placement VMW_PL_SYSTEM which
is very similar to TTM_PL_SYSTEM except that it allows
fencing. This fixes kernel oops'es during unloading of the driver
(and pci hot remove/add) which were caused by busy BO's in
TTM_PL_SYSTEM being present in the delayed deletion list in
TTM (TTM_PL_SYSTEM manager is destroyed before the delayed
deletions are executed)
