- * 2000/04/10: Nicolas Pitre <nico@cam.org>
+ * 2000/04/10: Nicolas Pitre <nico@fluxnic.net>
* - Big cleanup for dynamic selection of machine type at run time.
*
* 2000/07/19: Jamey Hicks <jamey@crl.dec.com>
* - convert dma address types to dma_addr_t
* - remove unused 'montype' stuff
* - remove redundant zero inits of init_var after the initial
- * memzero.
+ * memset.
* - remove allow_modeset (acornfb idea does not belong here)
*
* 2001/05/28: <rmk@arm.linux.org.uk>
* - Add patch 681/1 and clean up stork definitions.
