The port to Qt5 tried to preserve the same way as it used
to work with Qt3 and Qt4. However, at least with newer
versions of Qt5 (5.13), this doesn't work properly.
Change the schema by adding a vertical layout, in order
for it to start working properly again.

Both main config window and the item window have "Option"
name. That sounds weird, and makes harder to debug issues
of a window appearing at the wrong place.
So, change the title to reflect the contents of each
window.

The recommended way to initialize a null string is with
QString(). This is there at least since Qt5.5, with is
when qconf was ported to Qt5.

Nobody was opposed to raising minimum GCC version to 4.8 [1]
So, we will drop GCC <= 4.7 support sooner or later.
We always use C++ compiler for building plugins for GCC >= 4.8.
This commit drops the plugin support for GCC <= 4.7 a bit earlier,
which allows us to dump lots of code.

Currently, we disable -Wtautological-compare, which in turn disables a
bunch of more specific tautological comparison warnings that are useful
for the kernel such as -Wtautological-bitwise-compare. See clang's
documentation below for the other warnings that are suppressed by
-Wtautological-compare. Now that all of the major/noisy warnings have
been fixed, enable -Wtautological-compare so that more issues can be
caught at build time by various continuous integration setups.
-Wtautological-constant-out-of-range-compare is kept disabled under a
normal build but visible at W=1 because there are places in the kernel
where a constant or variable size can change based on the kernel
configuration. These are not fixed in a clean/concise way and the ones
I have audited so far appear to be harmless. It is not a subgroup but
rather just one warning so we do not lose out on much coverage by
default.

poly1305-x86_64-cryptogams.S is a generated file, so it should be
cleaned up by 'make clean'.
Assigning it to the variable 'targets' teaches Kbuild that it is a
generated file. However, this line is not evaluated when cleaning
because scripts/Makefile.clean does not include include/config/auto.conf.
Remove the ifneq-conditional, so this file is correctly cleaned up.

The currently minimum-supported binutils version 2.21 has the problem of
promoting symbols which are defined outside of a section into absolute.
According to Arvind:
binutils-2.21 and -2.22. An x86-64 defconfig will fail with
Invalid absolute R_X86_64_32S relocation: _etext
and after fixing that one, with
Invalid absolute R_X86_64_32S relocation: __end_of_kernel_reserve
Those two versions of binutils have a bug when it comes to handling
symbols defined outside of a section and binutils 2.23 has the proper
fix, see: https://sourceware.org/legacy-ml/binutils/2012-06/msg00155.html
Therefore, up to the fixed version directly, skipping the broken ones.
Currently shipping distros already have the fixed binutils version so
there should be no breakage resulting from this.
For more details about the whole thing, see the thread in Link.

Since we're doing a static inline dispatch here, we normally branch
based on whether or not there's an arch implementation. That would have
been fine in general, except the crypto Makefile prior used to turn
things off -- despite the Kconfig -- resulting in us needing to also
hard code various assembler things into the dispatcher too. The horror!
Now that the assembler config options are done by Kconfig, we can get
rid of the inconsistency.

We raise the minimal supported binutils version from time to time.
The last bump was commit 1fb12b35e5ff ("kbuild: Raise the minimum
required binutils version to 2.21").
We have these as-instr tests because binutils 2.21 does not support
them.
When we bump the binutils version next time, this will be a good
hint to find out which one can be dropped.
As for the Clang/LLVM builds, we require very new LLVM version,
so the LLVM integrated assembler supports all of them.

Doing this probing inside of the Makefiles means we have a maze of
ifdefs inside the source code and child Makefiles that need to make
proper decisions on this too. Instead, we do it at Kconfig time, like
many other compiler and assembler options, which allows us to set up the
dependencies normally for full compilation units. In the process, the
ADX test changes to use %eax instead of %r10 so that it's valid in both
32-bit and 64-bit mode.

You can build a user-space test program for the raid6 library code,
like this:
$ cd lib/raid6/test
$ make
The command in $(shell ...) function is evaluated by /bin/sh by default.
(or, you can specify the shell by passing SHELL=<shell> from command line)
Currently '>&/dev/null' is used to sink both stdout and stderr. Because
this code is bash-ism, it only works when /bin/sh is a symbolic link to
bash (this is the case on RHEL etc.)
This does not work on Ubuntu where /bin/sh is a symbolic link to dash.
I see lots of
/bin/sh: 1: Syntax error: Bad fd number
and
warning "your version of binutils lacks ... support"
Replace it with portable '>/dev/null 2>&1'.

It's definitely incorrect to mark the lock as taken even if
down_read_killable() failed.
This wass overlooked when we switched from down_read() to
down_read_killable() because down_read() won't fail while
down_read_killable() could.

lookup_node() uses gup to pin the page and get node information. It
checks against ret>=0 assuming the page will be filled in. However it's
also possible that gup will return zero, for example, when the thread is
quickly killed with a fatal signal. Teach lookup_node() to gracefully
return an error -EFAULT if it happens.
Meanwhile, initialize "page" to NULL to avoid potential risk of
exploiting the pointer.

A couple of misc fixes/workarounds for some issues that are causing a

Of most interest are the PCI power management and GR init WARs, which

When syzbot tries to figure out how to deduplicate bug reports, it prefers
seeing a hint about a specific bug type (we can do better than just
"UBSAN"). This lifts the handler reason into the UBSAN report line that
includes the file path that tripped a check. Unfortunately, UBSAN does
not provide function names.
