57b3006492 ACPI / LPSS: Save/restore LPSS private registers also on Lynxpoint
My assumption in commit b53548f9d9 ("spi: pxa2xx: Remove LPSS private
register restoring during resume") that Intel Lynxpoint and compatible
based chipsets may not need LPSS private registers saving and restoring
over suspend/resume cycle turned out to be false on Intel Broadwell.

Curtis Malainey sent a patch bringing above change back and reported the
LPSS SPI Chip Select control was lost over suspend/resume cycle on
Broadwell machine.

Instead of reverting above commit lets add LPSS private register
saving/restoring also for all LPSS SPI, I2C and UART controllers on
Lynxpoint and compatible chipset to make sure context is not lost in
case nothing else preserves it like firmware or if LPSS is always on.

Fixes: b53548f9d9 ("spi: pxa2xx: Remove LPSS private register restoring during resume")

Fixed pep8/flake8 python style code for lsvmbus tool.

The TAB indentation was on purpose ignored (pep8 rule W191) to make
sure the code is complying with the Linux code guideline.
The following command doe not show any warnings now:
pep8 --ignore=W191 lsvmbus
flake8 --ignore=W191 lsvmbus

b6143d10d2 arm64: ftrace: Ensure module ftrace trampoline is coherent with I-side
The initial support for dynamic ftrace trampolines in modules made use
of an indirect branch which loaded its target from the beginning of
a special section (e71a4e1beb ("arm64: ftrace: add support for far
branches to dynamic ftrace")). Since no instructions were being patched,
no cache maintenance was needed. However, later in be0f272bfc ("arm64:
ftrace: emit ftrace-mod.o contents through code") this code was reworked
to output the trampoline instructions directly into the PLT entry but,
unfortunately, the necessary cache maintenance was overlooked.

Add a call to __flush_icache_range() after writing the new trampoline
instructions but before patching in the branch to the trampoline.

a90118c445 x86/boot: Save fields explicitly, zero out everything else
Recent gcc compilers (gcc 9.1) generate warnings about an out of bounds
memset, if the memset goes accross several fields of a struct. This
generated a couple of warnings on x86_64 builds in sanitize_boot_params().

Fix this by explicitly saving the fields in struct boot_params
that are intended to be preserved, and zeroing all the rest.

[ tglx: Tagged for stable as it breaks the warning free build there as well ]

19bce474c4 ALSA: usb-audio: Fix a stack buffer overflow bug in check_input_term
`check_input_term` recursively calls itself with input from
device side (e.g., uac_input_terminal_descriptor.bCSourceID)
as argument (id). In `check_input_term`, if `check_input_term`
is called with the same `id` argument as the caller, it triggers
endless recursive call, resulting kernel space stack overflow.

This patch fixes the bug by adding a bitmap to `struct mixer_build`
to keep track of the checked ids and stop the execution if some id
has been checked (similar to how parse_audio_unit handles unitid
argument).

a982eeb09b io_uring: fix an issue when IOSQE_IO_LINK is inserted into defer list
This patch may fix two issues:

First, when IOSQE_IO_DRAIN set, the next IOs need to be inserted into
defer list to delay execution, but link io will be actively scheduled to
run by calling io_queue_sqe.

Second, when multiple LINK_IOs are inserted together with defer_list,
the LINK_IO is no longer keep order.

   |   LINK_IO   |      ----> insert to defer_list  -----------

99c79f6692 io_uring: fix manual setup of iov_iter for fixed buffers
Commit bd11b3a391 ("io_uring: don't use iov_iter_advance() for fixed
buffers") introduced an optimization to avoid using the slow
iov_iter_advance by manually populating the iov_iter iterator in some
cases.

However, the computation of the iterator count field was erroneous: The
first bvec was always accounted for an extent of page size even if the
bvec length was smaller.

In consequence, some I/O operations on fixed buffers were unable to
operate on the full extent of the buffer, consistently skipping some
bytes at the end of it.

edfbcb321f usb: add a hcd_uses_dma helper
The USB buffer allocation code is the only place in the usb core (and in
fact the whole kernel) that uses is_device_dma_capable, while the URB
mapping code uses the uses_dma flag in struct usb_bus.  Switch the buffer
allocation to use the uses_dma flag used by the rest of the USB code,
and create a helper in hcd.h that checks this flag as well as the
CONFIG_HAS_DMA to simplify the caller a bit.

    c) the error path in combination with driver removal causes
       imbalanced calls to the clk_*() and pm_()* APIs

a) happens because the original intended return value is
   overwritten (with 0) by the return code of
   regulator_disable() in ci_hdrc_imx_probe()'s error path
b) happens because ci_pdev is -EPROBE_DEFER, which causes
   ci_hdrc_remove_device() to OOPS

Fix a) by being more careful in ci_hdrc_imx_probe()'s error
path and not overwriting the real error code

Fix b) by calling the respective cleanup functions during
remove only when needed (when ci_pdev != NULL, i.e. when
everything was initialised correctly). This also has the
side effect of not causing imbalanced clk_*() and pm_*()
API calls as part of the error code path.

6caf0be40a USB: serial: option: Add Motorola modem UARTs
On Motorola Mapphone devices such as Droid 4 there are five USB ports
that do not use the same layout as Gobi 1K/2K/etc devices listed in
qcserial.c. So we should use qcaux.c or option.c as noted by
Dan Williams <dan.j.williams@intel.com>.

As the Motorola USB serial ports have an interrupt endpoint as shown
with lsusb -v, we should use option.c instead of qcaux.c as pointed out
by Johan Hovold <johan@kernel.org>.

The ff/ff/ff interfaces seem to always be UARTs on Motorola devices.
For the other interfaces, class 0x0a (CDC Data) should not in general
be added as they are typically part of a multi-interface function as
noted earlier by Bjørn Mork <bjorn@mork.no>.

However, looking at the Motorola mapphone kernel code, the mdm6600 0x0a
class is only used for flashing the modem firmware, and there are no
other interfaces. So I've added that too with more details below as it
works just fine.

The ttyUSB ports on Droid 4 are:

ttyUSB0 DIAG, CQDM-capable
ttyUSB1 MUX or NMEA, no response
ttyUSB2 MUX or NMEA, no response
ttyUSB3 TCMD
ttyUSB4 AT-capable

The ttyUSB0 is detected as QCDM capable by ModemManager. I think
it's only used for debugging with ModemManager --debug for sending
custom AT commands though. ModemManager already can manage data
connection using the USB QMI ports that are already handled by the
qmi_wwan.c driver.

To enable the MUX or NMEA ports, it seems that something needs to be
done additionally to enable them, maybe via the DIAG or TCMD port.
It might be just a NVRAM setting somewhere, but I have no idea what
NVRAM settings may need changing for that.

The TCMD port seems to be a Motorola custom protocol for testing
the modem and to configure it's NVRAM and seems to work just fine
based on a quick test with a minimal tcmdrw tool I wrote.

The voice modem AT-capable port seems to provide only partial
support, and no PM support compared to the TS 27.010 based UART
wired directly to the modem.

The UARTs added with this change are the same product IDs as the
Motorola Mapphone Android Linux kernel mdm6600_id_table. I don't
have any mdm9600 based devices, so I have only tested these on
mdm6600 based droid 4.

Then for the class 0x0a (CDC Data) mode, the Motorola Mapphone Android
Linux kernel driver moto_flashqsc.c just seems to change the
port->bulk_out_size to 8K from the default. And is only used for
flashing the modem firmware it seems.

I've verified that flashing the modem with signed firmware works just
fine with the option driver after manually toggling the GPIO pins, so
I've added droid 4 modem flashing mode to the option driver. I've not
added the other devices listed in moto_flashqsc.c in case they really
need different port->bulk_out_size. Those can be added as they get
tested to work for flashing the modem.

After this patch the output of /sys/kernel/debug/usb/devices has
the following for normal 22b8:2a70 mode including the related qmi_wwan
interfaces:
