Arnd Bergmann 78594b9599 ARM: add migrate_pages() system call
The migrate_pages system call has an assigned number on all architectures
except ARM. When it got added initially in commit d80ade7b32 ("ARM:
Fix warning: #warning syscall migrate_pages not implemented"), it was
intentionally left out based on the observation that there are no 32-bit
ARM NUMA systems.

However, there are now arm64 NUMA machines that can in theory run 32-bit
kernels (actually enabling NUMA there would require additional work)
as well as 32-bit user space on 64-bit kernels, so that argument is no
longer very strong.

Assigning the number lets us use the system call on 64-bit kernels as well
as providing a more consistent set of syscalls across architectures.
