  mm/mm_init: Introduce a boot parameter for check_pages (2025-12-04 19:40:25 +0200)

----------------------------------------------------------------
memblock: introduce check_pages boot parameter

... to decouple simple checks for page state on allocation and free from
CONFIG_DEBUG_VM.

check_pages parameter allows enabling page checking without building kernel
with CONFIG_DEBUG_VM or forcing init_on_{alloc, free} or other heavier
mechanisms.
