Patch series "Clean W=1 build warnings for mm/".
This is a janitorial only. During development of a tool to catch build
warnings early to avoid tripping the Intel lkp-robot, I noticed that mm/
is not clean for W=1. This is generally harmless but there is no harm in
cleaning it up. It disrupts git blame a little but on relatively obvious
lines that are unlikely to be git blame targets.
This patch (of 13):
make W=1 generates the following warning for vmscan.c
mm/vmscan.c:1814: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
It is not a kerneldoc comment and isolate_lru_pages() is a static

Currently most platforms define FIRST_USER_ADDRESS as 0UL duplication the
same code all over. Instead just define a generic default value (i.e 0UL)
for FIRST_USER_ADDRESS and let the platforms override when required. This
makes it much cleaner with reduced code.
The default FIRST_USER_ADDRESS here would be skipped in <linux/pgtable.h>
when the given platform overrides its value via <asm/pgtable.h>.

for (i = 0; i < count; i++, (u16 *)buf++)
^ ~~~~~
1 warning generated.
It appears the intention was to cast the void pointer to a u16 pointer
so that the data could be iterated through like an array of u16 values.
However, the cast happens after the increment because a cast is an
rvalue, whereas the post-increment operator only works on lvalues, so
the loop does not iterate as expected. This is not a bug in practice
because count is not greater than one at the moment but this could
change in the future so this should be fixed.
Replace the cast with a temporary variable of the proper type, which is
less error prone and fixes the iteration. Do the same thing for the
'u8 *' below this if block.

When using s2idle on a variety of AMD notebook systems, they are
experiencing spurious events that the EC or SMU are in the wrong
state leading to a hard time waking up or higher than expected
power consumption.
These events only occur when the EC GPE is inadvertently set as a wakeup
source. Originally the EC GPE was only set as a wakeup source when using
the intel-vbtn or intel-hid drivers in commit 10a08fd65e ("ACPI: PM:
Set up EC GPE for system wakeup from drivers that need it") but during
testing a reporter discovered that this was not enough for their ASUS
Zenbook UX430UNR/i7-8550U to wakeup by lid event or keypress.
Marking the EC GPE for wakeup universally resolved this for that
reporter in commit b90ff3554a ("ACPI: PM: s2idle: Always set up EC GPE
for system wakeup").
However this behavior has lead to a number of problems:
* On both Lenovo T14 and P14s the keyboard wakeup doesn't work, and
sometimes the power button event doesn't work.
* On HP 635 G7 detaching or attaching AC during suspend will cause
the system not to wakeup
* On Asus vivobook to prevent detaching AC causing resume problems
* On Lenovo 14ARE05 to prevent detaching AC causing resume problems
* On HP ENVY x360 to prevent detaching AC causing resume problems
As there may be other Intel systems besides ASUS Zenbook UX430UNR/i7-8550U
that don't use intel-vbtn or intel-hid, avoid these problems by only
universally marking the EC GPE wakesource on non-AMD systems.

If a writeback of the superblock fails with an I/O error, the buffer
is marked not uptodate. However, this can cause a WARN_ON to trigger
when we attempt to write superblock a second time. (Which might
succeed this time, for cerrtain types of block devices such as iSCSI
devices over a flaky network.)
Try to detect this case in flush_stashed_error_work(), and also change
__ext4_handle_dirty_metadata() so we always set the uptodate flag, not
just in the nojournal case.
Before this commit, this problem can be repliciated via:
1. dmsetup create dust1 --table '0 2097152 dust /dev/sdc 0 4096'
2. mount /dev/mapper/dust1 /home/test
3. dmsetup message dust1 0 addbadblock 0 10
4. cd /home/test
5. echo "XXXXXXX" > t
After a few seconds, we got following warning:

In testing out under development json-schema 2020-12 support, there's a
few issues with 'unevaluatedProperties' and the graph schema. If
'graph.yaml#/properties/port' is used, then neither the port nor the
endpoint(s) can have additional properties. 'graph.yaml#/$defs/port-base'
needs to be used instead.

The adv7180 binding is using 'bus-width' property, but doesn't document it.

These are backwards from Table 7-71 of the TLV320AIC3100 spec [1].
This was broken in 12eb4d66ba when BCLK_MASTER and WCLK_MASTER
were converted from 0x08 and 0x04 to BIT(2) and BIT(3), respectively.
-#define AIC31XX_BCLK_MASTER 0x08
-#define AIC31XX_WCLK_MASTER 0x04
+#define AIC31XX_BCLK_MASTER BIT(2)
+#define AIC31XX_WCLK_MASTER BIT(3)
Probably just a typo since the defines were not listed in bit order.

An IRQ handler may be called at any time after it is registered, so
anything it relies on must be ready before registration.
rockchip_pcie_subsys_irq_handler() and rockchip_pcie_client_irq_handler()
read registers in the PCIe controller, but we registered them before
turning on clocks to the controller. If either is called before the clocks
are turned on, the register reads fail and the machine hangs.
Similarly, rockchip_pcie_legacy_int_handler() uses rockchip->irq_domain,
but we installed it before initializing irq_domain.
Register IRQ handlers after their data structures are initialized and
clocks are enabled.
Found by enabling CONFIG_DEBUG_SHIRQ, which calls the IRQ handler when it
is being unregistered. An error during the probe path might cause this
unregistration and IRQ handler execution before the device or data
structure init has finished.

Commit 9b69d48c75 ("powerpc/64e: remove implicit soft-masking and
interrupt exit restart logic") limited the implicit soft masking and
restart logic to 64-bit Book3S only. However we are still building
restart_table.c for all 64-bit, ie. Book3E also.
There's no need to build it for 64e, and it also causes missing
prototype warnings for 64e builds, because the prototype is already
behind an #ifdef PPC_BOOK3S_64.

This release sees a nice new feature in the core from Morimoto-san,
support for automatic negotiation of DAI formats between the components
on the link. Otherwise the big highlight was the merging of the Tegra
machine drivers into a single driver avoiding a bunch of duplication.
