[PATCH] Remove SN PDA page overflow check

There's an obsolete check in sn_init_pdas() left over from the 2.4
days that panics if the cpu PDA and cpu_data area span more than a page.
With 2.6, we're not limited to a page, so remove the check entirely.

Patch against linux-2.5 bk.

Regards,
Greg Edwards
