Hi, I'm getting this build failure:

mm/page_alloc.c:424:3: error: call to undeclared function 'in_mem_hotplug'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  424 |                 in_mem_hotplug() ||

building next-20250304 on arm64

Caused by 

b4cfcc26f507 ("mm/page_alloc: add lockdep assertion for pageblock type change")
