b64aebbe79 arm64: dts: freescale: imx8qxp: Add fallback compatible for clock controller
Both i.MX8QM and i.MX8DXL use the fallback fsl,scu-clk compatible.
They rely on the same driver generic part as the i.MX8QXP, so
lets add it to i.MX8QXP too, for consitency.

c98e6e6836 arm64: dts: mt7622: fix BPI-R64 WPS button
The bananapi R64 (BPI-R64) experiences wrong WPS button signals.
In OpenWrt pushing the WPS button while powering on the device will set
it to recovery mode. Currently, this also happens without any user
interaction. In particular, the wrong signals appear while booting the
device or restarting it, e.g. after doing a system upgrade. If the
device is in recovery mode the user needs to manually power cycle or
restart it.

The official BPI-R64 sources set the WPS button to GPIO_ACTIVE_LOW in
the device tree. This setting seems to suppress the unwanted WPS button
press signals. So this commit changes the button from GPIO_ACTIVE_HIGH to
GPIO_ACTIVE_LOW.

The official BPI-R64 sources can be found on
https://github.com/BPI-SINOVOIP/BPI-R64-openwrt

the printouts.

There's a minor difference between the keys present on Hayato, which
uses an older layout, and Spherion, which uses a newer one.

20794545c1 arm64: kasan: Revert "arm64: mte: reset the page tag in page->flags"
This reverts commit e5b8d9218951e59df986f627ec93569a0d22149b.

Pages mapped in user-space with PROT_MTE have the allocation tags either
zeroed or copied/restored to some user values. In order for the kernel
to access such pages via page_address(), resetting the tag in
page->flags was necessary. This tag resetting was deferred to
set_pte_at() -> mte_sync_page_tags() but it can race with another CPU
reading the flags (via page_to_virt()):

P0 (mte_sync_page_tags):	P1 (memcpy from virt_to_page):
				  Rflags!=0xff
  Wflags=0xff
  DMB (doesn't help)
  Wtags=0
				  Rtags=0   // fault

Since now the post_alloc_hook() function resets the page->flags tag when
unpoisoning is skipped for user pages (including the __GFP_ZEROTAGS
case), revert the arm64 commit calling page_kasan_tag_reset().

70c248aca9 mm: kasan: Skip unpoisoning of user pages
Commit c275c5c6d50a ("kasan: disable freed user page poisoning with HW
tags") added __GFP_SKIP_KASAN_POISON to GFP_HIGHUSER_MOVABLE. A similar
argument can be made about unpoisoning, so also add
__GFP_SKIP_KASAN_UNPOISON to user pages. To ensure the user page is
still accessible via page_address() without a kasan fault, reset the
page->flags tag.

With the above changes, there is no need for the arm64
tag_clear_highpage() to reset the page->flags tag.

79e6820245 arm64: dts: renesas: Prepare AA1024XD12 panel .dtsi for overlay support
The Mitsubishi AA1024XD12 panel can be used for R-Car Gen2 and Gen3
boards as an optional external panel. It is described in the
arm/boot/dts/r8a77xx-aa104xd12-panel.dtsi file as a direct child of the
DT root node. This allows including r8a77xx-aa104xd12-panel.dtsi in
board device trees, with other minor modifications, to enable the panel.

This is however not how external components should be modelled. Instead
of modifying the board device tree to enable the panel, it should be
compiled as a DT overlay, to be loaded by the boot loader.

Prepare the r8a77xx-aa104xd12-panel.dtsi file for this usage by
declaring a panel node only, without hardcoding its path. Overlay
sources can then include r8a77xx-aa104xd12-panel.dtsi where appropriate.

This change doesn't cause any regression as r8a77xx-aa104xd12-panel.dtsi
is currently unused. As overlay support for this panel has only been
tested with Gen3 hardware, and Gen2 support will require more
development, move the file to arch/arm64/boot/dts/renesas/.
