Pull power management updates from Rafael Wysocki:
"The most significant change here is the extension of the Energy Model
to cover non-CPU devices (as well as CPUs) from Lukasz Luba.
There is also some new hardware support (Ice Lake server idle states

RAPL driver), some new functionality in the existing drivers (eg. a
new switch to disable/enable CPU energy-efficiency optimizations in
intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
devfreq), including the elimination of W=1 build warnings from cpufreq
done by Lee Jones.

- Removal of the tremendously unpopular read_barrier_depends() barrier,
which is a NOP on all architectures apart from Alpha, in favour of
allowing architectures to override READ_ONCE() and do whatever dance
they need to do to ensure address dependencies provide LOAD ->
LOAD/STORE ordering. This work also offers a potential solution if
compilers are shown to convert LOAD -> LOAD address dependencies into
control dependencies (e.g. under LTO), as weakly ordered architectures

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 and cross-arch updates from Catalin Marinas:
"Here's a slightly wider-spread set of updates for 5.9.
Going outside the usual arch/arm64/ area is the removal of
read_barrier_depends() series from Will and the MSI/IOMMU ID
translation series from Lorenzo.
The notable arm64 updates include ARMv8.4 TLBI range operations and
translation level hint, time namespace support, and perf.
Summary:
- Removal of the tremendously unpopular read_barrier_depends()
barrier, which is a NOP on all architectures apart from Alpha, in
favour of allowing architectures to override READ_ONCE() and do
whatever dance they need to do to ensure address dependencies
provide LOAD -> LOAD/STORE ordering.
This work also offers a potential solution if compilers are shown
to convert LOAD -> LOAD address dependencies into control
dependencies (e.g. under LTO), as weakly ordered architectures will
effectively be able to upgrade READ_ONCE() to smp_load_acquire().
The latter case is not used yet, but will be discussed further at
LPC.
- Make the MSI/IOMMU input/output ID translation PCI agnostic,
augment the MSI/IOMMU ACPI/OF ID mapping APIs to accept an input ID
bus-specific parameter and apply the resulting changes to the
device ID space provided by the Freescale FSL bus.
- arm64 support for TLBI range operations and translation table level

This function returns the first child object, but the returned pointer

Commit cc1c08edcc ("kconfig: qconf: don't show goback button on

This reverts commit cc1c08edcc.
Maxim Levitsky reports 'make xconfig' crashes since that commit
(https://lkml.org/lkml/2020/7/18/411)
Or, the following is simple test code that makes it crash:
menu "Menu"
config FOO
bool "foo"
default y
menuconfig BAR
bool "bar"
depends on FOO
endmenu
Select the Split View mode, and double-click "bar" in the right
window, then you will see Segmentation fault.
When 'last' is not set for symbolMode, the following code in
ConfigList::updateList() calls firstChild().
item = last ? last->nextSibling() : firstChild();
However, the pointer returned by ConfigList::firstChild() does not
seem to be compatible with (ConfigItem *), which seems another bug.
I'd rather want to reconsider whether hiding the goback icon is the
right thing to do.
In the following test code, the Split View shows "Menu2" and "Menu3"
in the right window. You can descend into "Menu3", but there is no way
to ascend back to "Menu2" from "Menu3".
menu "Menu1"
config FOO
bool "foo"
default y
menu "Menu2"
depends on FOO
menu "Menu3"
config BAZ
bool "baz"
endmenu
endmenu
endmenu
It is true that the goback button is currently not functional due to
yet another bug, but hiding the problem is not the right way to go.
Anyway, Segmentation fault is fatal. Revert the offending commit for
now, and we should find the right solution.

This reverts commit 5752ff07fd.
It added dead code to ConfigList:ConfigList().
The constructor of ConfigList has the initializer, mode(singleMode).
if (mode == symbolMode)
setHeaderLabels(QStringList() << "Item" << "Name" << "N" << "M" << "Y" << "Value");
else
setHeaderLabels(QStringList() << "Option" << "Name" << "N" << "M" << "Y" << "Value");
... always takes the else part.
The change to ConfigList::updateSelection() is strange too.
When you click the split view icon for the first time, the titles in
both windows show "Option". After you click something in the right
window, the title suddenly changes to "Item".
ConfigList::updateSelection() is not the right place to do this,
at least. It was not a good idea, I think.

Currently, qconf.moc is included from qconf.cc but they can be compiled
independently.
When you modify qconf.cc, qconf.moc does not need recompiling.
Rename qconf.moc to qconf-moc.cc, and split it out as an independent
compilation unit.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
Regenerate qconf.moc when the moc command is changed.
This also allows 'make mrproper' to clean it up. Previously, it was
not cleaned up because 'clean-files += qconf.moc' was missing.
Now 'make mrproper' correctly cleans it up because files listed in
'targets' are cleaned.

Pull v5.9 KCSAN bits from Paul E. McKenney.

Signed-off-by: Ingo Molnar <mingo@kernel.org>
The kbuild bot recently added the W=1 option, which triggered
documentation cleanups to squelch hundreds of kernel-doc warnings.
To make sure new kernel contributions don't add regressions to
kernel-doc descriptors, this patch suggests an option to treat
warnings as errors in CI/automated tests.
A -Werror command-line option is added to the kernel-doc script. When
this option is set, the script will return the number of warnings
found. The caller can then treat this positive return value as an
error and stop the build.
Using this command line option is however not straightforward when the
kernel-doc script is called from other scripts. To align with typical
kernel compilation or documentation generation, the Werror option is
also set by checking the KCFLAGS environment variable, or if
KDOC_WERROR is defined, as in the following examples:
KCFLAGS="-Wall -Werror" make W=1 sound/
KCFLAGS="-Wall -Werror" make W=1 drivers/soundwire/
KDOC_WERROR=1 make htmldocs
Note that in the last example the documentation build does not stop,
only an additional log is provided.

This is a s390 port of commit 548acf1923 ("x86/mm: Expand the
exception table logic to allow new handling options"), which is needed
for implementing BPF_PROBE_MEM on s390.
The new handler field is made 64-bit in order to allow pointing from
dynamically allocated entries to handlers in kernel text. Unlike on x86,
NULL is used instead of ex_handler_default. This is because exception
tables are used by boot/text_dma.S, and it would be a pain to preserve
ex_handler_default.
The new infrastructure is ignored in early_pgm_check_handler, since
there is no pt_regs.

-Wtype-limits is included in -Wextra which is added at W=1. It warns
(among other things) that 'comparison of an unsigned variable `< 0` is
always false. This causes noisy warnings, especially when used in
macros, hence it is more suitable for W=2.

The genpd infrastructure uses the terms master/slave, but such uses have
no external exposures (not even in Documentation/driver-api/pm/*) and are
not mandated by nor associated with any external specifications. Change
the language used through-out to parent/child.
There was one possible exception in the debugfs node
"pm_genpd/pm_genpd_summary" but its path has no hits outside of the
kernel itself when performing a code search[1], and it seems even this
single usage has been non-functional since it was introduced due to a
typo in the Python ("apend" instead of correct "append"). Fix the typo
while we're at it.

strsep() is neither standard C nor POSIX and used outside
the kernel code here. Using it here requires that the
build host supports it out of the box which is e.g.
not true for a Darwin build host and using a cross-compiler.
This leads to:
scripts/mod/modpost.c:145:2: warning: implicit declaration of function 'strsep' [-Wimplicit-function-declaration]
return strsep(stringp, "\n");
^
and a segfault when running MODPOST.
See also: https://stackoverflow.com/a/7219504
So let's replace this by strchr() instead of using strsep().
It does not hurt kernel size or speed since this code is run
on the build host.

The default implementation for setSelected() at QTreeWidgetItem
allows multiple items to be selected.
Well, this should never be possible for the configItem lists.
So, implement a function that will automatically clean any
previous selection. This simplifies the logic somewhat, while
making the selection logic to be applied atomically, avoiding
future issues on that.

The Qt5 conversion broke support for debug info links.
Restore the behaviour added by changeset
ab45d190fd ("kconfig: create links in info window").
The original approach was to pass a pointer for a data struct
via an <a href>. That doesn't sound a good idea, as, if something
gets wrong, the app could crash. So, instead, pass the name of
the symbol, and validate such symbol at the hyperlink handling
logic.

When the search dialog box finds symbols/menus that match
the search criteria, it presents all results at the window.
Clicking on a search result should make qconf to navigate
to the selected item. This works on singleMode and on
fullMode, but on splitMode, the navigation is broken.
This was partially caused by an incomplete Qt5 conversion
and by the followup patches that restored the original
behavior.
When qconf is on split mode, it has to update both the
config and the menu views. Right now, such logic is broken,
as it is not seeking using the right structures.
On qconf, the screen is split into 3 parts:
+------------+-------+
| | |
| Config | Menu |
| | |
+------------+-------+
| |
| ConfigInfo |
| |
+--------------------+
On singleMode and on fullMode, the menuView is hidden, and search
updates only the configList (which controls the ConfigView).
On SplitMode, the search logic should detect if the variable is a
leaf or not. If it is a leaf, it should be presented at the menuView,
and both configList and menuList should be updated. Otherwise, just
the configList should be updated.

There are two processed schema files:
- processed-schema-examples.yaml
Used for 'make dt_binding_check'. This is always a full schema.
- processed-schema.yaml
Used for 'make dtbs_check'. This may be a full schema, or a smaller
subset if DT_SCHEMA_FILES is given by a user.
If DT_SCHEMA_FILES is not specified, they are the same. You can copy
the former to the latter instead of running dt-mk-schema twice. This
saves the cpu time a lot when you do 'make dt_binding_check dtbs_check'
because building the full schema takes a couple of seconds.
If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated
based on the specified yaml files.
