d471e018c0 PM / OPP: Support adjusting OPP voltages at runtime
On some SoCs the Adaptive Voltage Scaling (AVS) technique is
employed to optimize the operating voltage of a device. At a
given frequency, the hardware monitors dynamic factors and either
makes a suggestion for how much to adjust a voltage for the
current frequency, or it automatically adjusts the voltage
without software intervention. Add an API to the OPP library for
the former case, so that AVS type devices can update the voltages
for an OPP when the hardware determines the voltage should
change. The assumption is that drivers like CPUfreq or devfreq
will register for the OPP notifiers and adjust the voltage
according to suggestions that AVS makes.

eca4625c95 Revert "UPSTREAM: usb: dwc3: core: Move the mode setting to the right place"
This reverts commit 1047560640.

This commit 1047560 will reinit dwc3 controller mode
when resuming dwc3 core. Generally, this patch can be
used for "dr_mode = host", "dr_mode = peripheral" and
"dr_mode = otg".

However, rockchip dwc3 core don't support otg function,
but only support DRD mode. So on rockchip platform, we
set dr_mode to otg for DRD mode, then switch host and
peripheral dynamically by extcon notifier. Also, we will
enable dwc3 to be a wakeup source and enable usb3 power
domain in suspend mode if usb device is pluged in. So
dwc3 controller will not lost the mode when resuming dwc3
core.

a6d73821f2 CHROMIUM: xhci: stop roothub port polling timer in shutdown
The xhci hcd use the port polling timer (rh_timer) to poll the
roothub for port events. But we can't allow the USB core to poll
the port events during shutdown because the xhci controller may
be disable and can't be accessed in shutdown. If we access xhci
port registers with port polling timer after xhci shutdown, it
may cause kernel crash or unexpected behavior. So we need to stop
the port polling timer while shutdown xhci.

I can easily reproduce the issue on rk3399 platform, plug in a
Type-C hub and an USB ethernet dongle, then do reboot test,
result in a crash with the following backtrace.

33e3a9340d CHROMIUM: xhci: do shutdown only hcd is registered
On some sepcial platforms (e.g. rk3399 platform), they will call
usb_remove_hcd() to remove xhci hcd if no device connected, and
also call xhci_stop() to halt and reset xhci. So we don't need to
do the same thing in shutdown if hcd has been unregistered.

In addition to remove hcd, rk3399 platform will disable xhci power
domain in runtime suspend, if we try to access xhci registers in
shutdown, it might cause kernel crash or unexpected behavior.

9f2b1a77cc CHROMIUM: usb: xhci-plat: use usb_hcd_platform_shutdown() callback
The xhci driver provides xhci_shutdown() to be called with the main
usb_hcd (the USB3 roothub) while do reboot. But actually, xhci-plat
never call xhci_shutdwon() during reboot because it doesn't use the
usb_hcd_platform_shutdown() helper.

So we use use usb_hcd_platform_shutdown() for xhci-plat, and the
normal shutdown call trace is:
kernel_restart -> kernel_restart_prepare -> device_shutdown ->
platform_drv_shutdown -> usb_hcd_platform_shutdown -> xhci_shutdown

590a3edaa4 ARM: pxa: pxa_cplds: fix interrupt handling
commit 9ba63e3cc8 upstream.

Since its initial commit, the driver is buggy for multiple interrupts
handling. The translation from the former lubbock.c file was not
complete, and might stall all interrupt handling when multiple
interrupts occur.

This is especially true when inside the interrupt handler and if a new
interrupt comes and is not handled, leaving the output line still held,
and not creating a transition as the GPIO block behind would expect to
trigger another cplds_irq_handler() call.

For the record, the hardware is working as follows.

The interrupt mechanism relies on :
 - one status register
 - one mask register

Let's suppose the input irq lines are called :
 - i_sa1111
 - i_lan91x
 - i_mmc_cd
Let's suppose the status register for each irq line is called :
 - status_sa1111
 - status_lan91x
 - status_mmc_cd
Let's suppose the interrupt mask for each irq line is called :
 - irqen_sa1111
 - irqen_lan91x
 - irqen_mmc_cd
Let's suppose the output irq line, connected to GPIO0 is called :
 - o_gpio0

The behavior is as follows :
 - o_gpio0 = not((status_sa1111 & irqen_sa1111) |
		 (status_lan91x & irqen_lan91x) |
		 (status_mmc_cd & irqen_mmc_cd))
   => this is a N-to-1 NOR gate and multiple AND gates
 - irqen_* is exactly as programmed by a write to the FPGA
 - status_* behavior is governed by a bi-stable D flip-flop
   => on next FPGA clock :
     - if i_xxx is high, status_xxx becomes 1
     - if i_xxx is low, status_xxx remains as it is
     - if software sets status_xxx to 0, the D flip-flop is reset
       => status_xxx becomes 0
       => on next FPGA clock cycle, if i_xxx is high, status_xxx becomes
	  1 again

Also use memset instead of strncpy to set the partition's name. It's

c60955f446 perf symbols: Fixup symbol sizes before picking best ones
commit 432746f8e0 upstream.

When we call symbol__fixup_duplicate() we use algorithms to pick the
"best" symbols for cases where there are various functions/aliases to an
address, and those check zero size symbols, which, before calling
symbol__fixup_end() are _all_ symbols in a just parsed kallsyms file.

So first fixup the end, then fixup the duplicates.

Found while trying to figure out why 'perf test vmlinux' failed, see the
output of 'perf test -v vmlinux' to see cases where the symbols picked
as best for vmlinux don't match the ones picked for kallsyms.

8d31e5f994 perf symbols: Check symbol_conf.allow_aliases for kallsyms loading too
commit c97b40e4d1 upstream.

We can allow aliases to be kept, but we were checking this just when
loading vmlinux files, be consistent, do it for any symbol table loading
code that calls symbol__fixup_duplicate() by making this function check
.allow_aliases instead.

349eb2cf6d perf hists browser: Fix event group display
commit d9ea48bc4e upstream.

Milian reported that the event group on TUI shows duplicated overhead.
This was due to a bug on calculating hpp->buf position.  The
hpp_advance() was called from __hpp__slsmg_color_printf() on TUI but
it's already called from the hpp__call_print_fn macro in __hpp__fmt().
The end result is that the print function returns number of bytes it
printed but the buffer advanced twice of the length.

This is generally not a problem since it doesn't need to access the
buffer again.  But with event group, overhead needs to be printed
multiple times and hist_entry__snprintf_alignment() tries to fill the
space with buffer after it printed.  So it (brokenly) showed the last
overhead again.

The bug was there from the beginning, but I think it's only revealed
when the alignment function was added.

9c72ae999e s390/con3270: fix insufficient space padding
commit 6cd997db91 upstream.

con3270 contains an optimisation that reduces the amount of data to be
transmitted to the 3270 terminal by putting a Repeat to Address (RA)
order into the data stream. The RA order itself takes up space, so
con3270 only uses it if there's enough space left in the line
buffer. Otherwise it just pads out the line manually.

For lines that were _just_ short enough that the RA order still fit in
the line buffer, the line was instead padded with an insufficient
amount of spaces. This was caused by examining the size of the
allocated line buffer rather than the length of the string to be
displayed.

For con3270_cline_end(), we just compare against the line length. For
con3270_update_string() however that isn't available anymore, so we
check whether the Repeat to Address order is present.

8b47784918 s390/con3270: fix use of uninitialised data
commit c14f2aac7a upstream.

con3270 contains an optimisation that reduces the amount of data to be
transmitted to the 3270 terminal by putting a Repeat to Address (RA)
order into the data stream. The RA order itself takes up space, so
con3270 only uses it if there's enough space left in the line
buffer. Otherwise it just pads out the line manually.

For lines too long to include the RA order, one byte was left
uninitialised. This was caused by an off-by-one bug in the loop that
pads out the line. Since the buffer is allocated from a common pool,
the single byte left uninitialised contained some previous buffer
content. Usually this was just a space or some character (which can
result in clutter but is otherwise harmless). Sometimes, however, it
was a Repeat to Address order, messing up the entire screen layout and
causing the display to send the entire buffer content on every
keystroke.

commit d53c51f261 upstream.

Since commit 9f3d6d7 chsc_get_channel_measurement_chars is called with
interrupts disabled during resume from hibernate. Since this function
used spin_unlock_irq, interrupts have been enabled accidentally. Fix
this by using the irqsave variant.

Since we can't guarantee the IRQ-enablement state for all (future/
external) callers, change the locking in related functions to prevent
similar bugs in the future.

fcf5e5198b x86/mm: Expand the exception table logic to allow new handling options
commit 548acf1923 upstream.

Huge amounts of help from  Andy Lutomirski and Borislav Petkov to
produce this. Andy provided the inspiration to add classes to the
exception table with a clever bit-squeezing trick, Boris pointed
out how much cleaner it would all be if we just had a new field.

Linus Torvalds blessed the expansion with:

  ' I'd rather not be clever in order to save just a tiny amount of space
    in the exception table, which isn't really criticial for anybody. '

The third field is another relative function pointer, this one to a
handler that executes the actions.

We start out with three handlers:

 1: Legacy - just jumps the to fixup IP
 2: Fault - provide the trap number in %ax to the fixup code
 3: Cleaned up legacy for the uaccess error hack

90bc49cd66 dmaengine: ipu: remove bogus NO_IRQ reference
commit 86c7e68364 upstream.

A workaround for a warning introduced a use of the NO_IRQ
macro that should have been gone for a long time.

It is clear from the code that the value cannot actually
be used, but apparently there was a configuration at
some point that caused a warning, so instead of just
reverting that patch, this rearranges the code in a way that
the warning cannot reappear.

to determine if the caller was in atomic mode. Most of the mistakes
were corrected with commit 33dc85c3c6

commit a3930ed060 upstream.

Commit d88429a695 ("ASoC: dapm: Add output driver widget") added
the snd_soc_dapm_out_drv ID for the output driver widget, which is
the same as the PGA widget, with a later power sequence number.

Commit 19a2557b76 ("ASoC: dapm: Add kcontrol support for PGAs")
then added kcontrol support for PGA widgets, but failed to account
for output driver widgets. Attempts to use kcontrols with output
driver widgets result in silent failures, with the developer having
little idea about what went on.

Add snd_soc_dapm_out_drv to the switch/case block under snd_soc_dapm_pga
in dapm_create_or_share_kcontrol, since they are essentially the same.
