You don't have to. Just reorder the patches as suggested by Sam. (First,
make everybody ignore the return value, then change these return types
to void.)
BTW you can mention in this commit log, that this change is possible
after a3123fd0a4a5. That commit made tty_standard_install to always
return 0.

Although this doesn't get into the Linux kernel coding style

Many drivers with tty use the tty_stand_install(). But, there is no
need to handle the error, since it always returns 0. So, change the
return type of tty_standard_install() and tty_port_install() to void
type and remove unnecessary exception handling where we use these
functions.

In lparcfg_write we hard code kbuf_sz and then use this as the variable
length of kbuf creating a variable length array. Since we're hard coding
the length anyway just define the array using this as the length and
remove the need for kbuf_sz, thus removing the variable length array.

* [PATCH 1/2] powerpc/prom: Remove VLA in prom_check_platform_support()
From: Suraj Jitindar Singh @ 2018-09-05 2:09 UTC (permalink / raw)
To: linuxppc-dev; +Cc: mpe, mikey, joel, Suraj Jitindar Singh
In-Reply-To: <20180905020951.10372-1-sjitindarsingh@gmail.com>
In prom_check_platform_support() we retrieve and parse the
"ibm,arch-vec-5-platform-support" property of the chosen node.
Currently we use a variable length array however to avoid this use an
array of constant length 8.
This property is used to indicate the supported options of vector 5
bytes 23-26 of the ibm,architecture.vec node. Each of these options
is a pair of bytes, thus for 4 options we have a max length of 8 bytes.

__builtin_ctz(val) is undefined for val == 0.

If running maddhd does not work, will running it in kernel mode work?
I think you should *actually* emulate it.
(Same for the next patch, "darn", but emulation of that is much more
interesting).

The mod instruction has special cases that aren't handled by this C code,
too (divide by 0, or signed division of the most negative number by -1).
For the mod intruction the behaviour is undefined in those cases, but you
probably should force some specific behaviour. You don't want the kernel
to execute a trap instruction, etc. :-)

* Regression from patch 'tty: hvc: hvc_poll() break hv read loop'
From: Jason Gunthorpe @ 2018-09-04 17:48 UTC (permalink / raw)
To: Nicholas Piggin, Michael Ellerman
Cc: linuxppc-dev, linux-kernel, Leon Romanovsky
Hi Nicholas,
I am testing 4.19-rc2 and I see bad behavior with my qemu hvc0
console..
Running interactive with qemu (qemu-2.11.2-1.fc28) on the console
providing hvc0, using options like:
-nographic
-chardev stdio,id=stdio,mux=on,signal=off
-mon chardev=stdio
-device isa-serial,chardev=stdio
-device virtio-serial-pci
-device virtconsole,chardev=stdio
I see the hvc0 console hang regularly, ie doing something like 'up
arrow' in bash causes the hvc0 console to hang. Prior kernels worked
OK.
Any ideas? I'm not familiar with this code.. Thanks!

Subject: [PATCH] tty: hvc: hvc_poll() break hv read loop
Avoid looping with the spinlock held while there is read data
being returned from the hv driver. Instead note if the entire
size returned by tty_buffer_request_room was read, and request
another read poll.
This limits the critical section lengths, and provides more
even service to other consoles in case there is a pathological
condition.

I agree. Perhaps we should have a 00-DESCRIPTION file in each
directory, and each file could start with a:
DESCRIPTION: <one line description here>
and then these files could be generated by those that have these tags.

"dt-bindings: soc: ..." for the subject
It is obvious reading the diff you are removing fsl,#rcpm-wakeup-cell.
What is not obvious is why? The commit msg should answer that.
You also are mixing several things in this patch like adding ls1012
which you don't mention. Please split.
