Subject: tile: add missing definition of MAP_LOCKONFAULT
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
Fixes: c5827483ad6b ("mm: mmap: add mmap flag to request VM_LOCKONFAULT")
