Commit c5827483ad6b ("mm: mmap: add mmap flag to request VM_LOCKONFAULT") defines and uses MAP_LOCKONFAULT, but does not to add the definition for the tile architecture. This results in the following build error.
include/linux/mman.h: In function 'calc_vm_flag_bits': include/linux/mman.h:90:9: error: 'MAP_LOCKONFAULT' undeclared
