Subject: [PATCH] Remove SN PDA page overflow check
Date: Mon, 26 Apr 2004 18:42:50 +0000 [thread overview]
Message-ID: <20040426184250.GH5165@sgi.com> (raw)
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
