Subject: [PATCH][BUILDERR] mm: Fix build error with !CONFIG_HUGETLBFS

In commit 5a6fe1259506 an extra parameter was added to hugetlb_file_setup(),
but the header file was not updated for the !CONFIG_HUGETLBFS case, which
results in:
    
ipc/shm.c:371:49: error: macro "hugetlb_file_setup" passed 3 arguments,
    but takes just 2
