Try make KALLSYMS_EXTRA_PASS=1 as a workaround
make[2]: *** [../Makefile:1162: vmlinux] Error 1
Setting KALLSYMS_EXTRA_PASS=1 does not help.
This is caused by the compiler inserting stubs such as *.long_branch.*
and *.plt_branch.*
$ powerpc-linux-nm -n .tmp_vmlinux.kallsyms2
[ snip ]
c00000000210c010 t 00000075.plt_branch.da9:19

...
Actually, the problem mentioned in scripts/link-vmlinux.sh comments;
"In theory it's possible this results in even more stubs, but unlikely"
is happening here, and ends up with another kallsyms step required.
scripts/kallsyms.c already ignores various compiler stubs. Let's do
similar to make kallsysms for PowerPC always succeed in 2 steps.

Commit 09854ba94c ("mm: do_wp_page() simplification") reorganized all
the code around the page re-use vs copy, but in the process also moved
the final unlock_page() around to after the wp_page_reuse() call.
That normally doesn't matter - but it means that the unlock_page() is
now done after releasing the page table lock. Again, not a big deal,
you'd think.
But it turns out that it's very wrong indeed, because once we've
released the page table lock, we've basically lost our only reference to
the page - the page tables - and it could now be free'd at any time. We
do hold the mmap_sem, so no actual unmap() can happen, but madvise can
come in and a MADV_DONTNEED will zap the page range - and free the page.
So now the page may be free'd just as we're unlocking it, which in turn
will usually trigger a "Bad page state" error in the freeing path. To
make matters more confusing, by the time the debug code prints out the
page state, the unlock has typically completed and everything looks fine
again.
This all doesn't happen in any normal situations, but it does trigger
with the dirtyc0w_child LTP test. And it seems to trigger much more
easily (but not expclusively) on s390 than elsewhere, probably because
s390 doesn't do the "batch pages up for freeing after the TLB flush"
that gives the unlock_page() more time to complete and makes the race
harder to hit.

Previously, when you double-clicked the "int", "hex", or "string" menus,
a line-edit gadget showed up to allow you to input the value, which
looked clumsy.
Also, it was buggy; the editor opened even if the config option was not
editable. For example, just try to double-click CC_VERSION_TEXT, which
has no prompt.
This commit sub-classes QStyleItemDelegate to allow users to edit
"int", "hex", "string" menus in-place. Just double-click (or press
the F2 key) in the data column. Then, an editor widget is placed on
top of the item view.
The two methods are overridden:
createEditor - process only when the data column is being accessed
and the menu is visible. Otherwise, return nullptr to disallow editing.
setModelData - take the new data from the editor, and set it to the
addressed symbol. If it was successful, update all the list windows.
Otherwise, (the reason for the failure is possibly the input data was
out of range), set the old value back to the editor.

This commit also avoids the same -fsanitize=* flags being added to
CFLAGS_UBSAN multiple times.
Prior to this commit, the ubsan flags were appended by the '+='
operator, without any initialization. Some build targets such as
'make bindeb-pkg' recurses to the top Makefile, and ended up with
adding the same flags to CFLAGS_UBSAN twice.

There was a request to preprocess the module linker script like we
do for the vmlinux one. (https://lkml.org/lkml/2020/8/21/512)
The difference between vmlinux.lds and module.lds is that the latter
is needed for external module builds, thus must be cleaned up by
'make mrproper' instead of 'make clean'. Also, it must be created
by 'make modules_prepare'.
You cannot put it in arch/$(SRCARCH)/kernel/, which is cleaned up by
'make clean'. I moved arch/$(SRCARCH)/kernel/module.lds to
arch/$(SRCARCH)/include/asm/module.lds.h, which is included from
scripts/module.lds.S.
scripts/module.lds is fine because 'make clean' keeps all the
build artifacts under scripts/.

The Snow Ridge integrated PCIe3 uncore unit can be used to collect
performance data, e.g. utilization, between PCIe devices, plugged into
the PCIe port, and the components (in M2IOSF) responsible for
translating and managing requests to/from the device. The performance
data is very useful for analyzing the performance of PCIe devices.
The device with the PCIe3 uncore PMON units is owned by the portdrv_pci
driver. Create a PCI sub driver for the PCIe3 uncore PMON units.
Here are some difference between PCIe3 uncore unit and other uncore
pci units.
- There may be several Root Ports on a system. But the uncore counters
only exist in the Root Port A. A user can configure the channel mask
to collect the data from other Root Ports.
- The event format of the PCIe3 uncore unit is the same as IIO unit of
SKX.
- The Control Register of PCIe3 uncore unit is 64 bits.
- The offset of each counters is 8, which is the same as M2M unit of
SNR.
- New MSR addresses for unit control, counter and counter config.

Some uncore counters may be located in the configuration space of a PCI
device, which already has a bonded driver. Currently, the uncore driver
cannot register a PCI uncore PMU for these counters, because, to
register a PCI uncore PMU, the uncore driver must be bond to the device.
However, one device can only have one bonded driver.
Add an uncore PCI sub driver to support such kind of devices.
The sub driver doesn't own the device. In initialization, the sub
driver searches the device via pci_get_device(), and register the
corresponding PMU for the device. In the meantime, the sub driver
registers a PCI bus notifier, which is used to notify the sub driver
once the device is removed. The sub driver can unregister the PMU
accordingly.
The sub driver only searches the devices defined in its id table. The
id table varies on different platforms, which will be implemented in the
following platform-specific patch.

It is advised to use module_name() macro instead of dereferencing mod->name
directly. This makes sense for consistencys sake and also it prevents a
hard dependency to CONFIG_MODULES.

GPIO_U is mapped to the least significant byte of input/output mask, and
the byte in "output" mask should be 0 because GPIO_U is input only. All
the other bits need to be 1 because GPIO_V/W/X support both input and
output modes.
Similarly, GPIO_Y/Z are mapped to the 2 least significant bytes, and the
according bits need to be 1 because GPIO_Y/Z support both input and
output modes.

Add a label property for the AT24 EEPROM to allow a custom name to be
used for identifying the EEPROM on a board. This is useful when there
is more than one EEPROM present.

The AT24 EEPROM driver does not initialise the 'id' field of the
nvmem_config structure and because the entire structure is not
initialised, it ends up with a random value. This causes the NVMEM
driver to append the device 'devid' value to name of the NVMEM
device. Ideally for I2C devices such as the AT24 that already have a
unique name, we would not bother to append the 'devid'. However, given
that this has always been done for AT24 devices, we cannot remove the
'devid' as this will change the name of the userspace sysfs node for
the NVMEM device. Nonetheless we should ensure that the 'id' field of
the nvmem_config structure is initialised so that there is no chance of
a random value causes problems in the future. Therefore, set the NVMEM
config.id to NVMEM_DEVID_AUTO for AT24 EEPROMs so that the 'devid' is
always appended.

After fixing mac80211 to allow larger A-MSDUs in some cases, there have been
reports of performance regressions and packet loss with some clients.
It appears that the issue occurs when the hardware is transmitting A-MSDUs
bigger than 8k. Limit the local VHT MPDU size capability to 7991, matching
the value used for MT7915 as well.

Currently, the IRQ setup for the SGPIO driver enables all interrupts in
dual-edge trigger mode. Since the default handler is handle_bad_irq, any
state change on input GPIOs will trigger bad IRQ warnings.
This change applies sensible IRQ defaults: single-edge trigger, and all
IRQs disabled.

Currently, the aspeed-sgpio driver exposes up to 80 GPIO lines,
corresponding to the 80 status bits available in hardware. Each of these
lines can be configured as either an input or an output.
However, each of these GPIOs is actually an input *and* an output; we
actually have 80 inputs plus 80 outputs.
This change expands the maximum number of GPIOs to 160; the lower half
of this range are the input-only GPIOs, the upper half are the outputs.
We fix the GPIO directions to correspond to this mapping.
This also fixes a bug when setting GPIOs - we were reading from the
input register, making it impossible to set more than one output GPIO.

When pca953x_irq_pending returns false, the pending parameter won't
