PSI provides a canonical way to see resource pressure increases as
they develop, with pressure metrics for three major resources:
memory, CPU, and IO. PSI stats are like barometers that provide
fair warning of impending resource shortages, enabling users to
take more proactive, granular, and nuanced steps when resources
start becoming scarce.

This solution that is needed for some routers to provide proper
LED activity when controlled directly by the MV88E6xxx switch,
has just been merged in upstream Linux.
Make this patch 901 as other backports from earlier kernels
are in patch 896 and this is the first free number after
that.
Patch offsets in pending patches are augmented as part of
the refresh.

Backport BLOCK OF support patch merged upstream and refresh pending
BLOCK patches.
This is a new way to declare partition table for BLOCK device (eMMC
currently supported) with the use of DTS.
Current pending patch are adapted to not cause regression with current
downstream implementation of a similar functionality.
Also enable the new OF_PARTITION config by default.

RELR is a relocation packing format for relative relocations.
Linux has supported using it for ARM64 since 5.4, and more recently
for LoongArch as well.
It requires compatible tooling as well, so only with binutils 2.43
TOOLS_SUPPORT_RELR is set and thus RELR available.
RELR should always decrease the binary size and while testing this
the default build for Dynalink WRX-36 (qualcommax/ipq807x) reduced
the compressed kernel size by 38k and uncompressed one by 640k.
So, lets enable it in the default config.

Enable the CONFIG_ARM64_PAN kernel security option, which leverages the
ARMv8.1 Privileged Access Never (PAN) extension to prevent the kernel
from directly accessing user space memory.
Instead, copy_to_user and similar functions must be used for data
transfer between kernel and user space. This feature is automatically
disabled at runtime on CPUs without PAN support, making it a no-op in
those cases.

Activate the kernel option CONFIG_LIST_HARDENED for all targets.
This adds some inline checks to list_add() and list_del() operations
in the kernel. Before kernel 6.6 these checks were only available with
CONFIG_DEBUG_LIST option, but now a light version is available which
should only add very few extra instructions to such operations.
The performance penalty is very low from my point of view. It should
make it much harder to use bugs in Linux kernel list handling when
exploiting the Linux kernel.

Add the KERNEL_BTRFS_FS config option so that targets can select
whether BTRFS support must be built-in.
Select this option (alongside KERNEL_BTRFS_FS_POSIX_ACL) from the
layerscape/armv8_64b subtarget instead of enabling it in
target/linux/layerscape/armv8_64b/config-* files.
Move disabling of CONFIG_BTRFS_FS_CHECK_INTEGRITY into generic configs.
This makes it possible for OpenWRT to be built with built-in BTRFS
support on specific boards, instead of whole targets.

Commit ec885796c0 switched the crc32 implementation from default to
byte-at-a-time algorithm, which runs slower but consumes less memory.
A decade has passed, and we have already abandoned targets that had
small memory, so switch it back to default for faster speed.

Allow a wider audience to test this pending series.
Use about to be submitted v3 which factors out block notification support.
Apart from dropping the no longer needed (and problematic) fallback for
for the 'partitions' node being present at the device parent there are
no intended functional changes.
As opening a block device as file is not supported yet in Kernel v6.6,
use the previous method as backporting seems a bit too involving.

When kernel 6.6 is being compiled with GCC13 it will prompt for:
Compressed Debug information
> 1. Don't compress debug information (DEBUG_INFO_COMPRESSED_NONE)
2. Compress debugging information with zlib (DEBUG_INFO_COMPRESSED_ZLIB)
3. Compress debugging information with zstd (DEBUG_INFO_COMPRESSED_ZSTD) (NEW)
This is because kernel now also has support for compressing debug info
with ZSTD, so add the missing symbol and disable it by default.
