Tetsuo Handa 8f9e86ee79 staging: android: ion: Bail out upon SIGKILL when allocating memory.
syzbot found that a thread can stall for minutes inside
ion_system_heap_allocate() after that thread was killed by SIGKILL [1].
Let's check for SIGKILL before doing memory allocation.

Jan Sebastian Götte 92e3e88488 Staging: fbtft: Fix GPIO handling
Commit c440eee1a7 ("Staging: fbtft: Switch to the gpio descriptor
interface") breaks GPIO handling. In several places, checks to only set
a GPIO if it was configured ended up backwards.
I have tested this fix. The fixed driver works with a ili9486
display connected to a raspberry pi via SPI.

Phil Reid b918d1c270 Staging: fbtft: Fix reset assertion when using gpio descriptor
Typically gpiod_set_value calls would assert the reset line and
then release it using the symantics of:
	gpiod_set_value(par->gpio.reset, 0);
	... delay
	gpiod_set_value(par->gpio.reset, 1);
And the gpio binding would specify the polarity.

Prior to conversion to gpiod calls the polarity in the DT
was ignored and assumed to be active low. Fix it so that
DT polarity is respected.

Phil Reid dbc4f989c8 Staging: fbtft: Fix probing of gpio descriptor
Conversion to use gpio descriptors broke all gpio lookups as
devm_gpiod_get_index was converted to use dev->driver->name for
the gpio name lookup. Fix this by using the name param. In
addition gpiod_get post-fixes the -gpios to the name so that
shouldn't be included in the call. However this then breaks the
of_find_property call to see if the gpio entry exists as all
fbtft treats all gpios as optional. So use devm_gpiod_get_index_optional
instead which achieves the same thing and is simpler.

Nishad confirmed the changes where only ever compile tested.

Linus Torvalds f632a8170a Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)

Paul Walmsley cc0e5f1ce0 scripts/spelling.txt: drop "sepc" from the misspelling list
The RISC-V architecture has a register named the "Supervisor Exception
Program Counter", or "sepc".  This abbreviation triggers checkpatch.pl's
misspelling detector, resulting in noise in the checkpatch output.  The
risk that this noise could cause more useful warnings to be missed seems
to outweigh the harm of an occasional misspelling of "spec".  Thus drop
the "sepc" entry from the misspelling list.

[akpm@linux-foundation.org: fix existing "sepc" instances, per Joe]

Linus Torvalds 1f7563f743 SCSI sg on 20190709
This topic branch covers a fundamental change in how our sg lists are
 allocated to make mq more efficient by reducing the size of the
 preallocated sg list.  This necessitates a large number of driver
 changes because the previous guarantee that if a driver specified
 SG_ALL as the size of its scatter list, it would get a non-chained
 list and didn't need to bother with scatterlist iterators is now
 broken and every driver *must* use scatterlist iterators.
 
 This was broken out as a separate topic because we need to convert all
 the drivers before pulling the trigger and unconverted drivers kept
 being found, necessitating a rebase.

Linus Torvalds e9a83bd232 It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro.  These create more
    than the usual number of simple but annoying merge conflicts with other
    trees, unfortunately.  He has a lot more of these waiting on the wings
    that, I think, will go to you directly later on.
 
  - A new document on how to use merges and rebases in kernel repos, and one
    on Spectre vulnerabilities.
 
  - Various improvements to the build system, including automatic markup of
    function() references because some people, for reasons I will never
    understand, were of the opinion that :c:func:``function()`` is
    unattractive and not fun to type.
 
  - We now recommend using sphinx 1.7, but still support back to 1.4.
 
  - Lots of smaller improvements, warning fixes, typo fixes, etc.

Merge tag 'docs-5.3' of git://git.lwn.net/linux

Pull Documentation updates from Jonathan Corbet:
 "It's been a relatively busy cycle for docs:

   - A fair pile of RST conversions, many from Mauro. These create more
     than the usual number of simple but annoying merge conflicts with
     other trees, unfortunately. He has a lot more of these waiting on
     the wings that, I think, will go to you directly later on.

   - A new document on how to use merges and rebases in kernel repos,
     and one on Spectre vulnerabilities.

   - Various improvements to the build system, including automatic
     markup of function() references because some people, for reasons I
     will never understand, were of the opinion that
     :c:func:``function()`` is unattractive and not fun to type.

   - We now recommend using sphinx 1.7, but still support back to 1.4.

   - Lots of smaller improvements, warning fixes, typo fixes, etc"

Christian Müller 0dbc8368ed drivers/staging/rtl8192u: style nonstyled comments
The coding-styles.rst states, that multiline comments should
allways contain a leading "*" in each line.
For multiline comments in general they

/*
 * should look
 * like this.
 */

For multiline comments in either net/ or drivers/net/ however,
they should

/* omit
 * the first
 * empty line.
 */

Since this file is part of a networking driver, the goal for it would
be to reside in drivers/net/ one day.

This patch changes comments, that were in neither form of the two listed
above, to have the style that is specified for drivers/net/.

Christian Müller d8718e45e2 drivers/staging/rtl8192u: drop first comment line
As stated in coding-styles.rst multiline comments should be structured in a way,
that the actual comment starts on the second line of the commented portion. E.g:

/*
 * Multiline comments
 * should look like
 * this.
 */

However, there is an exception to files in drivers/net/ and net/, where
multiline comments are prefered to look like this:

/* Mutliline comments for
 * drivers/net/ should look
 * like this.
 */

The comments in this file initially looked like the first example.
But since this file is part of a networking driver and thus should
be moved to drivers/net/ one day, this patch adjusts the comments
such that they are fitting to the style imposed for drivers/net/.

NeilBrown baa3477f06 staging: mt7621-dts: add support for second network interface
The mt7621 has two network interfaces, one that connects to an
internal switch, and one that can connect to either that switch
or an external phy, or possibly an internal phy.

The Gnubee-PC2 has an external phy for use with the second interface.

This patch add some support for the second interface to mt7621.dtsi
and add a gbpc2.dts which makes use of this.  This allows the second
interface to be used.

I don't fully understand how to configure this interface - the
documentation is thin - so there could well be room for improvement
here.
