Does anyone know if __NR_migrate_pages for arm exists and just isnt in the "unistd.h" file?

arch/arm/include/asm/unistd.h says:

/* * Unimplemented (or alternatively implemented) syscalls */ #define __IGNORE_fadvise64_64 #define __IGNORE_migrate_pages

and the git log says: commit d80ade7b323152672bf66e74ec11c324332f6d1e Author: Russell King rmk+kernel@arm.linux.org.uk Date: Sun Sep 27 17:40:03 2009 +0100

ARM: Fix warning: #warning syscall migrate_pages not implemented

We're not implementing this syscall (we're not NUMA) so we might as well silence this warning.

so I'd guess it isn't implemented on ARM and wont be in the near term.
