Subject: [PATCH v3 1/7] ia64: add __NR_old_getpagesize in uapi/asm/unistd.h

sys_getpagesize entry is present in entry.S file to support
for old user interface. So we need to add an uapi entry too.

Add __NR_old_getpagesize in order to not break old user space
as it is reserved for backwards compatibility with old __NR_
getpagesize.
