Bump the image kernel from 5.4.86 to the 6.18.35 LTS line, now that the
GCC 14 toolchain is in place (previous commit).
- kernel-download.make: LINUX_VERSION 5.4.86 -> 6.18.35.
- Non-versioned base config: LINUX_CONFIG falls back to a shared
conf/kernel/linux.<arch>.config (per-version configs under
conf/kernel/<release>/ are still preferred when a platform ships one),
so a kernel bump needs no new committed config.
- The .config recipe now runs "make olddefconfig" (via the cross
toolchain, hence the order-only XTOOLS_BUILD_STAMP dep) to reconcile
the base config to the kernel actually being built.
- Module signing: 6.18 dropped MODULE_SIG_KEY_SRCPREFIX and resolves
CONFIG_MODULE_SIG_KEY relative to the build tree, so after olddefconfig
rewrite a configured signing key to the absolute path of the generated
key (replacing the MODULE_SIG_KEY_SRCPREFIX passed on the build line).
- conf/kernel/linux.x86_64.config, conf/kernel/linux.armv8a.config,
patches/kernel/6.18.35/series, upstream/linux-6.18.35.tar.xz.sha1.

123 platforms carry an empty kernel patch series, so they have no version-bound kernel code. Drop their LINUX_VERSION / LINUX_MINOR_VERSION pins and let them ride the default kernel (now 6.18 LTS) instead of an EOL line. This modernizes them and lets them build on the GCC 14 toolchain again (they need no kernel-build leniency flags, having no patches). Platforms that DO carry kernel patches keep their pin -- their patches are written against that specific kernel and would not apply to 6.18. Signed-off-by: Brad House <bhouse@nexthop.ai>
cls_ds4101 carries kernel patches (cls-lpc-basecpld, enable-kernel-spcr) but pinned no kernel version, so it floated on the default. The toolchain milestone bumped the default to 6.18 LTS, which its older patches do not apply to. Pin it to 5.4.86 -- the prior default it was already building against -- so this change is a no-op for the platform. Whether it still builds on the modern toolchain is its owner's concern; this only avoids us silently moving it off its kernel. Signed-off-by: Brad House <bhouse@nexthop.ai>
…ect configs Nine x86 platforms (the Dell C2xxx/S-series family + agema_ag7648c) each carried a kernel patch whose sole purpose was to add a platform Kconfig symbol that select()ed a fixed set of standard Intel SoC options (I2C_ISCH, I2C_ISMT, GPIO_SCH, MFD_CORE, LPC_SCH) with no driver code. Replace each with those CONFIG_* set directly in the machine kernel config and drop the patch. The aggregator was each platform's only kernel patch, so with it gone they carry no version-bound kernel code: drop their LINUX_VERSION pins too and let them ride the default kernel (6.18 LTS, which builds under GCC 14). The five options were verified to survive `make olddefconfig` against the 6.18 base config. Signed-off-by: Brad House <bhouse@nexthop.ai>

Targets
onie-modernization-2026. This is the second half of the old toolchain milestone (#1119): the kernel bump, stacked on top of the toolchain PR (#1129).Depends on (merge first): #1129 (and transitively #1125/#1126/#1127/#1128). Until the toolchain PR merges into
onie-modernization-2026, this PR's diff also includes the toolchain PR's commits; I'll rebase once it lands so the diff narrows to just the kernel commits below.What this does (own commits, on top of the toolchain PR)

The
KERNEL_OLD_GCC_COMPATchange in the toolchain PR builds the old 5.4 kernel under GCC 14, which breaks the old toolchain↔kernel build cycle and lets the kernel bump be reviewed/rolled back on its own.
