mm/hugetlb: extract sysctl into hugetlb_sysctl.c
Following the extraction of sysfs code, this patch moves the sysctl
interface implementation into a dedicated file to further improve code
organization and maintainability of the hugetlb subsystem.
The following components are moved to mm/hugetlb_sysctl.c:
- proc_hugetlb_doulongvec_minmax()
- hugetlb_sysctl_handler_common()
- hugetlb_sysctl_handler()
- hugetlb_mempolicy_sysctl_handler() (CONFIG_NUMA)
- hugetlb_overcommit_handler()
- hugetlb_table[] sysctl table definition
- hugetlb_sysctl_init()
The hugetlb_internal.h header file is updated to declare the sysctl
initialization function with proper #ifdef guards for configurations
without CONFIG_SYSCTL support.
The Makefile is updated to compile hugetlb_sysctl.o when CONFIG_HUGETLBFS
is enabled. This refactoring reduces the size of hugetlb.c and logically
separates the sysctl interface from core hugetlb management code.
MAINTAINERS is updated to add new file hugetlb_sysctl.c.
No functional changes are introduced; all code is moved as-is from
hugetlb.c with consistent formatting.
