Subject: [PATCH 3/7] - New SN hardware support - boot_init_shub2
Date: Thu, 11 Aug 2005 17:26:28 +0000 [thread overview]
Message-ID: <20050811172628.GA18265@sgi.com> (raw)
Update the addresses of the pio_write_status_addr so that
they are correct for newer processors. Shub2 did not number
the threads in the order that I had expected.
