sys_move_pages() is an optional syscall, and once we remove the compat version of it in favor of the native one with an in_compat_syscall() check, the x32 syscall table refers to a __x32_sys_move_pages symbol that may not exist when the syscall is disabled.
Change the COND_SYSCALL() definition on x86 to also include the redirection for x32.
