mm: hugetlb: fix type of hugetlb_treat_as_movable variable
hugetlb_treat_as_movable declared as unsigned long, but
proc_dointvec() used for parsing it:
static struct ctl_table vm_table[] = {
...
{
.procname = "hugepages_treat_as_movable",
.data = &hugepages_treat_as_movable,
.maxlen = sizeof(int),
.mode = 0644,
.proc_handler = proc_dointvec,
},
This seems harmless, but it's better to use int type here.
