The inclusion of linux/vmalloc.h, which is required for its definition of set_vm_flush_reset_perms(), is somehow dependent on asm/realmode.h being included by asm/acpi.h. Explicitly include linux/vmalloc.h so that a future patch can drop the realmode.h include from asm/acpi.h without breaking the build.
