Declare a variable with the static qualifier if it is of file scope and
not used in another file.
v1 -> v2:
* remove the unnecessary change to the following variables, which is
due to the report issue
struct multiboot_info *mbi = (struct multiboot_info *)
(HPA2HVA((uint64_t)boot_regs[1]));
struct multiboot_mmap *mmap =
(struct multiboot_mmap *)
HPA2HVA((uint64_t)mbi->mi_mmap_addr);
