Commit 29bb45f25f (regmap-mmio: Use native endianness for read/write)
attempted to fix some long standing bugs in the MMIO implementation for
big endian systems caused by duplicate byte swapping in both regmap and
readl()/writel() which affected MIPS systems as when they are in big
endian mode they flip the endianness of all registers in the system, not
just the CPU. MIPS systems had worked around this by declaring regmap
using IPs as little endian which is inaccurate, unfortunately the issue
had not been reported.
Sadly the fix makes things worse rather than better. By changing the
behaviour to match the documentation it caused behaviour changes for
other IPs which broke them and by using the __raw I/O accessors to avoid
the endianness swapping in readl()/writel() it removed some memory
ordering guarantees and could potentially generate unvirtualisable
instructions on some architectures.
Unfortunately sorting out all this mess in any half way sensible fashion
was far too invasive to go in during an -rc cycle so instead let's go
back to the old broken behaviour for v4.5, the better fixes are already
queued for v4.6. This does mean that we keep the broken MIPS DTs for
another release but that seems the least bad way of handling the
situation.

drm/dp/mst: deallocate payload on port destruction
drm/dp/mst: Reverse order of MST enable and clearing VC payload table.
drm/dp/mst: move GUID storage from mgr, port to only mst branch
drm/dp/mst: change MST detection scheme

drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil
drm/mst: Add range check for max_payloads during init
drm/mst: Don't ignore the MST PBN self-test result
drm: fix missing reference counting decrease
This is needed to properly deallocate port payload
after downstream branch get unplugged.
In order to do this unplugged MST topology should
be preserved, to find first alive port on path to
unplugged MST topology, and send payload deallocation
request to branch device of found port.
For this mstb and port kref's are used in reversed
order to track when port and branch memory could be
freed.
Added additional functions to find appropriate mstb
as described above.

of 1st MST, GUID is not created for 2nd MST branch. When downstream port of
2nd MST branch send upstream request, it fails because 2nd MST branch GUID
is not available.

1. Get edid for all connected MST displays, not only on logical ports,
in the same thread as MST topology detection is done:
There are displays that have branches inside w/o logical ports.
So in case another SST display connected downstream system can
end-up in situation when 3 DOWN requests sent: two for
‘remote i2c read’ and one for ‘enum path resources’, making slots full.
2. Call notification callback in one place in the end of topology discovery/update:
This is done to reduce number of events sent to userspace in case complex
topology discovery is going, adding multiple number of connectors;
3. Remove notification callback call from short pulse interrupt processing function:
This is done in order not to block interrupt processing function, in case any
MST request will be made from it. Notification will be send from topology
discovery/update work item.

drm_fixp_from_fraction allows us to create a fixed point directly

xhci_find_next_ext_cap doesn't check for PCI hotplug removal and may use
the PCI master abort bit pattern (~0) to calculate a new PCI address
offset to read/write. The has lead to reproducable crashes when testing
surprise removal during device initialization on a Stratus platform, at
least after commit d5ddcdf4d6 ("xhci: rework xhci extended capability
list parsing functions").
The crash is repeatable on a Stratus platform when injecting hardware
faults to induce xHCI host controller hotplug during driver
initialization. If a PCI read in xhci_find_next_ext_cap returns the
master abort pattern, quirk_usb_handoff_xhci may start using a bogus
ext_cap_offset to start searching more bogus PCI addresses.

The DTSI file for the Nomadik does not properly specify how the
PL180 levelshifter is connected: the Nomadik actually needs all
the five st,sig-dir-* flags set to properly control all lines out.
Further this board supports full power cycling of the card, and
since this variant has no hardware clock gating, it needs a
ridiculously low frequency setting to keep up with the ever
overflowing FIFO.
The pin configuration set-up is a bit of a mystery, because of
course these pins are a mix of inputs and outputs. However the
reference implementation sets all pins to "output" with
unspecified initial value, so let's do that here as well.

Ensure that the take argument is a valid bucket ID before indexing the

We were indexing the buckets array without verifying the index was
within the [0,max_buckets) range. This could happen because
a multistep rule does not have enough buckets and has CRUSH_ITEM_NONE
for an intermediate result, which would feed in CRUSH_ITEM_NONE and
make us crash.

In ALSA timer core, the active timer instance is managed in
active_list linked list. Each element is added / removed dynamically
at timer start, stop and in timer interrupt. The problem is that
snd_timer_interrupt() has a thinko and leaves the element in
active_list when it's the last opened element. This eventually leads
to list corruption or use-after-free error.
This hasn't been revealed because we used to delete the list forcibly
in snd_timer_stop() in the past. However, the recent fix avoids the
double-stop behavior (in commit [f784beb75ce8: ALSA: timer: Fix link
corruption due to double start or stop]), and this leak hits reality.
This patch fixes the link management in snd_timer_interrupt(). Now it
simply unlinks no matter which stream is.

changeset 70433a152f ("media: videobuf2: Refactor vb2_fileio_data
and vb2_thread") broke videobuf2-dvb.
The root cause is that, instead of calling threadio->fnc() for
all types of events except for VB2_BUF_STATE_ERROR, it was calling
it only for VB2_BUF_STATE_DONE.
With that, the DVB thread were never called.

The vb2_thread implementation was made generic and was moved from
videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately
that clearly was never tested since it broke read() causing NULL address
references.
The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb
pointer in various core functions).
The v4l2_buffer no longer exists after moving the code into the core and
it is no longer needed. However, the vb2_thread code passed a pointer to
a vb2_buffer to the core functions were a v4l2_buffer pointer was expected
and vb2_thread expected that the vb2_buffer fields would be filled in
correctly.
This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the
pb pointer is a void pointer, so no type-checking took place.
This patch fixes this problem:
1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use
a NULL pointer here since they don't care about v4l2_buffer anyway.
2) let vb2_core_dqbuf pass back the index of the received buffer. This is
all vb2_thread needs: this index is the index into the q->bufs array
and vb2_thread just gets the vb2_buffer from there.
3) the fileio->b pointer (that originally contained a v4l2_buffer) is
removed altogether since it is no longer needed.
Tested with vivid and the cobalt driver.

The tda1004x was updating the properties cache before locking.
If the device is not locked, the data at the registers are just
random values with no real meaning.
This caused the driver to fail with libdvbv5, as such library
calls GET_PROPERTY from time to time, in order to return the
DVB stats.

xhci driver frees data for all devices, both usb2 and and usb3 the
first time usb_remove_hcd() is called, including td_list and and xhci_ring
structures.
When usb_remove_hcd() is called a second time for the second xhci bus it
will try to dequeue all pending urbs, and touches td_list which is already
freed for that endpoint.

During probe, in the device tree case, the data pointer associated to a
compatible is dereferenced. However, not all the compatibles are
associated to a private data pointer.
The generic-xhci and the xhci-platform don't need them, this patch adds a
test on the data pointer before accessing it, avoiding a kernel crash.

when ip fails to enter sleep mode, register access protection will
be disabled, at the same time if all clocks are disabled, access
register will hang up AHB bus.
the common case causes ip sleep failure is that after all ports
enter U3 but before ip enters sleep mode, a port receives a resume
signal('K'). this will happens when such as clicks mouse to try to
do remote-wakeup to stop system enter suspend.
so stop polling root hubs to avoid access xHCI register on bus
suspend, and restart it when bus resumes.

XHCI_SSIC_PORT_UNUSED quirk was applied to the xHCI host controllers
in some Intel SoC chips. With this quirk applied, SSIC port is set
to "unused" prior to xhci_suspend(). This may cause problem if host
fails to suspend. In this case, the port is set to unused without
host further entering D3, and the port will not be usable anymore.

XHCI_PME_STUCK_QUIRK. These two workarounds actually are different and
might happen on different hardwares. Need to separate them by adding a

Commit abce329c27 ("xhci: Workaround to get D3 working in Intel xHCI")
adds a workaround for a limitation of PME storm caused by SSIC port in
some Intel SoCs. This commit only handled one SSIC port, while there
are actually two SSIC ports in the chips. This patch handles both SSIC
ports. Without this fix, users still see PME storm.
