"page_counter.h" does not need <linux/kernel.h>. <linux/limits.h> is enough
to get LONG_MAX.
Files that include page_counter.h are limited. They have been compile
tested or checked.
$ git grep page_counter\.h
include/linux/hugetlb_cgroup.h: struct page_counter hugepage[HUGE_MAX_HSTATE];
--> all files that include it have been compile tested
include/linux/memcontrol.h:#include <linux/page_counter.h>
--> <linux/kernel.h> has been added, to be safe
include/net/sock.h:#include <linux/page_counter.h>
--> already include <linux/kernel.h>
mm/hugetlb_cgroup.c:#include <linux/page_counter.h>
mm/memcontrol.c:#include <linux/page_counter.h>
mm/page_counter.c:#include <linux/page_counter.h>
--> compile tested
