ramips: restore CONFIG_PAGE_BLOCK_MAX_ORDER=10 for 6.18

namiltd · hauke · commit 5213918c3d95 · 2026-04-08T00:00:24.000+02:00
Restore CONFIG_PAGE_BLOCK_MAX_ORDER=10 in ramips 6.18 config fragments to fix build failures where PAGE_BLOCK_MAX_ORDER was undefined. Support for Linux 6.18 on ramips was added after this OpenWrt change: openwrt/openwrt@ac0cb87. Before that integration, the kernel option CONFIG_PAGE_BLOCK_MAX_ORDER=10 was provided in target/linux/generic/config-6.18 and applied broadly. After the ramips 6.18 integration the generic fragment no longer supplied this option for ramips targets, which caused some backported code paths and drivers to assume PAGE_BLOCK_MAX_ORDER was defined and led to compilation failures.
