By switching to the LINUX_DTBS variable, the post-image.sh script can now
work regardless of whether a user is using BR2_LINUX_KERNEL_INTREE_DTS_NAME
or the BR2_LINUX_KERNEL_CUSTOM_DTS_DIR for custom hardware. This simplifies
the transition users will make when migrating from a zynqmp evaluation board
to a zynqmp custom platform.
To keep the example post-image script as simple as possible, it assumes that
the first DTB in the LINUX_DTBS list is the one for creating the system.dtb
filename that u-boot will use for booting. Users are free to implement their
own post-image scripts for use cases with multiple DTBs.

When running iperf3 with Linux 6.18.51 on VisionFive 2, one CPU core
stays at 100% load during the test, while network throughput is limited
to approximately 793 Mbits/sec:
[ ID] Interval Transfer Bitrate
[ 5] 0.00-10.01 sec 945 MBytes 793 Mbits/sec receiver
The regression was introduced in Linux 6.14 by commit df542f669307
("net: stmmac: Switch to zero-copy in non-XDP RX path"). It leads to
misaligned access exceptions when parsing packet headers. During the
iperf3 test, perf stat reported approximately 9.6 million alignment
faults over 5 seconds:
$ perf stat -a -e alignment-faults -- sleep 5
Performance counter stats for 'system wide':
9620073 alignment-faults
5.029337000 seconds time elapsed
The kernel must emulate these unaligned accesses, resulting in
significant overhead.
The issue was fixed in Linux 6.18.52 [1]. Bump Linux to 6.18.55, the
latest stable release at the time of writing, to include the fix.

Since the bump to version 2.13.0 in Buildroot commit [1],
atop fails to build with musl:
drawbar.c:2336:33: error: implicit declaration of function 'waddwstr'; did you mean 'waddstr'? [-Wimplicit-function-declaration]
(Before 2.13.0, the same configurations already failed earlier on
uClibc because _POSIX_C_SOURCE was defined without a value. Upstream
fixed that in 2.13.0 by giving it an explicit value, but the same
pattern remains for _XOPEN_SOURCE.)
ncurses only declares its wide-character API, including waddwstr(),
when NCURSES_WIDECHAR is set. If the application does not set it,
curses.h derives it from the feature test macros:
#if defined(_XOPEN_SOURCE_EXTENDED) || \
(defined(_XOPEN_SOURCE) && (_XOPEN_SOURCE - 0 >= 500))
drawbar.c defines _XOPEN_SOURCE with an empty value, which makes the
check evaluate as 0 >= 500 and fail.
This only breaks with musl because of the C library's <features.h>,
which curses.h pulls in through <stdio.h> before doing the check.
glibc and uClibc both redefine _XOPEN_SOURCE to 700 and define
_XOPEN_SOURCE_EXTENDED whenever _GNU_SOURCE is set, which drawbar.c
does, so the empty definition gets fixed up. musl never modifies the
application's feature test macros, so the empty value reaches
curses.h and the wide-character prototypes are left out.
Add a patch that defines _XOPEN_SOURCE as 700, matching the
_POSIX_C_SOURCE value of 200809L that is already used.

Add support for pzstd, the multi-threaded implementation of zstd.
The pzstd build requires C++ and threads support. On some architectures
(e.g., Microblaze, SPARC), it also requires linking against libatomic
due to the use of atomic operations.
Ensure that -latomic is passed in LDFLAGS during both the build and
install phases. Consistently passing LDFLAGS is necessary because the
pzstd Makefile re-links the binary during the 'install' target due to
its dependency on the static library.
Fixes build failures reported with bootlin-microblazeel-uclibc and
bootlin-sparc-uclibc toolchains:
Pzstd.cpp:(.text+0x17e8): undefined reference to '__atomic_compare_exchange_1'
Pzstd.cpp:(.text._ZN5pzstd15BufferWorkQueue3popERNS_6BufferE): undefined reference to '__atomic_fetch_sub_4'
For host-zstd, always build pzstd. It just adds a few seconds of
build time.

Libtool 2.6.x is starting to be used by upstreams when generating
release tarballs (e.g. cryptsetup-2.8.8). As LIBTOOL_PATCH_HOOK does
not know about it, ltmain.sh is left unpatched, so libtool relinks
libraries at install time and adds -L/usr/lib, which is rejected by
the toolchain wrapper:
i686-buildroot-linux-gnu-gcc: ERROR: unsafe header/library path used in cross-compilation: '-L/usr/lib'
The v2.4.4 patch no longer applies cleanly, so add a v2.6 variant,
rebased on libtool 2.6.2, and use it for 2.6.x versions.

SQLiteCpp has an internal setting for stack protection which defaults
to "on". Since Buildroot handles stack protection itself this is not
needed and more importantly it causes problems as the option enables
stack protection support even when the toolchain doesn't support it,
as can be reproduced using the following defconfig:
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_X86_I686_MUSL_BLEEDING_EDGE=y

Upstream changelog:
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/1.58.1/NEWS?ref_type=tags
Changes relevant for Buildroot build:
* Support for dhclient has been removed, drop the conditional block
for BR2_PACKAGE_DHCP_CLIENT=y.
* NetworkManager now installs a systemd generator to manage its initrd
units, disable it if building without systemd or for systemd without
initrd support by setting the target system generator directory to
"no" [1]. Note that the current upstream main branch adds a build
option for initrd support, likely to be released with 1.60.x, which
should supersede removing the initrd units and disabling the
generator when building with systemd.
* Contrary to what the NEWS file states, the new "clat" build option
is enabled by default. Disable it, (optionally) enabling would
require libbpf and a suitable BPF compiler.

To have consistent guidance on building disk images with genimage,
update the docs to recommend using the UAPI Root Filesystem types. The
UAPI Root Filesystem types are part of the UAPI Discoverable Partitions
