Remove SN PDA page overflow check
PATCH 1/1 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
