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.

It seems that we have some kind of a symbol name conflict which causes
CONFIG_SECCOMP to always be read as y.
Unfortunatelly, I could not figure out what is causing this, but simply
renaming SECCOMP to USE_SECCOMP seems to properly work and leaves the
symbol unset unless arch dependencies are satisfied.
This fixes qoriq and others that dont support seccomp from failing due
to procd-seccomp package being selected to get included but it cannot be
built for them:

Expose Kernel's CONFIG_MPTCP option and enable it by default for
!SMALL_FLASH targets.
The idea behind enabling it by default is to allow users of the binary
distribution to make use of MPTCP tunneling for link aggregation.
Using MPTCP for link aggregation is an often discussed topic in the
forum and there is even a whole OpenWrt fork (MPTCPRouter) just for that.
Enabling the kernel-side of the story by default will allow using MPTCP
on vanilla OpenWrt without having to build anything from source.

Add target for Loongson LoongArch64-based boards.
LoongArch is a new RISC ISA developed by Loongson. It's a bit like
MIPS or RISC-V. LoongArch includes both 32-bit and 64-bit versions
(LoongArch32/LoongArch64).
Loongson 3A5000 and 3A6000 are the two existing CPUs of LoongArch64
and is used for PC products. It's BIOS supports ACPI and UEFI-only
boot. These CPUs supports SMP and SMT.
At present only LoongArch64 is supported by linux kernel.
Toolchain requirement:
binutils >= 2.40
gcc >= 13.1

Increasing the size of the rootfs_data filesystem has become a ever
repeating discussion and seems to be the most important thing for
users of the MediaTek-based BananaPi boards.
Using the whole remaining size of a microSD or the eMMC for rootfs_data
doesn't make sense for many reasons, but neither does the current
default of 104 MiB for the 'rootfs' partition size.
Increase the 'rootfs' partition size to 448 MiB which will result in
the sdcard image being exactly 512 MiB. Finding a microSD card smaller
than 512 MiB and still working could anyway be difficult in 2024.
That will allow users to install even bloatware written in Go or other
space-hungry languages while still leaving most of the space unallocated
for additional partitions or volumes to be used for persistent user
data.

At the moment we have to manually follow the default GCC version
also in config/Config-kernel.in. This tends to be forgotten at GCC
version bumps (just happened when switching from version 12 to 13).
Instead, introduce a hidden Kconfig symbol which implies KERNEL_WERROR
in toolchain/gcc/Config.in where it is visible for developers changing
the default version.
Also remove the explicit default on BUILDBOT to avoid a circular
dependency and also because buildbots anyway implicitly always select
the default GCC version.

The GCC option -fstack-protector-all is a security feature used to protect against stack-smashing attacks.
This option enhances the stack-smashing protection provided by -fstack-protector-strong.
-fstack-protector-all option applies stack protection to all functions, regardless of their characteristics.
While this offers the most comprehensive protection against stack-smashing attacks, it can significantly impact
the performance of the program because every function call includes additional checks for stack integrity.
This option can incur a performance penalty because of the extra checks added to every function call,
but it significantly enhances security, making it harder for attackers to exploit buffer overflows to execute arbitrary code.
It's particularly useful in scenarios where security is paramount and performance trade-offs are acceptable.

Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.
No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.
Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.
