arch/cris/arch-v32/drivers/mach-a3/gpio.c:
+spin_lock_irqrestore(&gpio_lock, flags);
arch/cris/arch-v32/drivers/mach-a3/gpio.c:
+spin_lock_irqrestore(&gpio_lock, flags);
should that not be "spin_unlock_irqrestore()"?
The code in question was inside an (most often) undefined ifdef.

Changes as suggested by Andrew Morton, plus general cleanup to
ease later consolidation of driver into machine common driver.
- Correct parameter type of gpio_write to const char __user *
- Remove volatile from the arrays of machine dependent registers, use
readl and writel to access them instead.
- Remove useless casts of void.
- Use spin_lock_irqsave for locking.
- Break gpio_write into smaller sub-functions.
- Remove useless breaks after returns.
- Don't perform any change in IO_CFG_WRITE_MODE if values are invalid.
(previously values were set and then set to zero)
- Change cast for copy_to_user to (void __user *)
- Make file_operations gpio_fops static and const.
- Make setget_output static. (However, it's still inline since the CRIS
architecture is still not SMP, which makes the function small enough
to inline)

Clean up issues noticed by Andrew Morton:
- Use a combined struct for allocating the mtd_info and nand_chip structs
instead of using anonymous memory as the example in
Documentation/DocBook/mtdnand.tmpl
- Use kzalloc instead of using kmalloc/memset(0)
- Make crisv32_device_ready static.
