* [Blackfin] arch: move the init sections to the end of memoryMike Frysinger2008-02-02
| | | | | | | | | | | | | | | Move the init sections to the end of memory so that after they are free, run time memory is all continugous - this should help decrease memory fragementation. When doing this, we also pack some of the other sections a little closer together, to make sure we don't waste memory. To make this happen, we need to rename the .data.init_task section to .init_task.data, so it doesn't get picked up by the linker script glob.

| * CRIS v32: Change drivers/i2c.c locking.Jesper Nilsson2008-02-08
| | | | | | | | | | | | | | - Change spin_lock + local_irq_save into spin_lock_irqsave - Change spin_unlock + local_irq_restore into spin_unlock_irqrestore - Return ENOTTY if ioctl is not recognized as a cris ioctl. - Make init functions static.
| * CRIS v32: Rewrite ARTPEC-3 gpio driver to avoid volatiles and general cleanup.Jesper Nilsson2008-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)

| * CRIS v32: Clean up nandflash.c for ARTPEC-3 and ETRAX FS.Jesper Nilsson2008-02-08
| | | | | | | | | | | | | | | | | | | | 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.
| * CRIS v10: Cleanup of drivers/gpio.cJesper Nilsson2008-02-08
| | | | | | | | | | | | | | | | | | | | | | - Change parameters of gpio_write (const char * buf -> const char __user *buf) - Don't initialize static variables to zero. - Remove useless casts from void. - Change name of interrupt routine (gpio_pa_interrupt -> gpio_interrupt) - Use kzmalloc instead of allocating memory and zeroing it manually. - Correct casts for copy_to_user and copy_from_user to (void __user *) - Make file_operations gpio_fops static. - Make ioif_watcher static, not used outside this file.
