I have to wonder why this has taken so long to be fixed ...

I have applied this patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Wed, 29 Jun 2011 15:52:00 +1000
Subject: [PATCH] net: include io.h in for iounmap etc

fixes these build errors:

drivers/net/can/sja1000/sja1000_of_platform.c: In function 'sja1000_ofp_read_reg':
drivers/net/can/sja1000/sja1000_of_platform.c:61:2: error: implicit declaration of function 'in_8'
drivers/net/can/sja1000/sja1000_of_platform.c: In function 'sja1000_ofp_write_reg':
drivers/net/can/sja1000/sja1000_of_platform.c:67:2: error: implicit declaration of function 'out_8'
drivers/net/can/sja1000/sja1000_of_platform.c: In function 'sja1000_ofp_remove':
drivers/net/can/sja1000/sja1000_of_platform.c:81:2: error: implicit declaration of function 'iounmap'
drivers/net/can/sja1000/sja1000_of_platform.c: In function 'sja1000_ofp_probe':
drivers/net/can/sja1000/sja1000_of_platform.c:113:2: error: implicit declaration of function 'ioremap_nocache'
drivers/net/can/sja1000/sja1000_of_platform.c:113:7: warning: assignment makes pointer from integer without a cast

Caused by commit b7f080cfe223 ("net: remove mm.h inclusion from
netdevice.h").
