Brief description of the config / packaging change.

• Config change (enable/disable/modify a symbol)
• Driver enablement
• Upstream version bump / rebase
• Patch add/drop
• Packaging / recipe change
• Documentation update

• Config normalized with make olddefconfig (not make defconfig)
• git diff of the config is exactly the intended symbols
• Kernel package builds
• Boot-tested in a VM (QEMU + OVMF, UEFI)
• Change confirmed via zcat /proc/config.gz / dmesg

• No boot-critical option disabled (UEFI CONFIG_EFI*, root filesystem, block/initramfs)
• Low-latency preemption profile preserved
• Upstream delta kept small and justified
• Source integrity verified (checksum / signature) for version bumps
