* lib/scatterlist.o needed by a module only - link it in unconditionallyGuennadi Liakhovetski2008-02-081-2/+2
| | | | | | | | | | | | | lib/scatterlist.c is needed by drivers/media/video/videobuf-dma-sg.c, and we would like to be able to use the latter without PCI too, for example, on PXA270 ARM CPU. It is then possible to create a configuration with CONFIG_BLOCK=n, where only module code will need scatterlist.c. Therefore it must be in obj-y.

* Fix FRV cmpxchg_localMathieu Desnoyers2008-02-083-84/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the FRV cmpxchg_local by breaking the following header dependency loop : linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h -> asm-frv/system.h -> asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h and linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h -> asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h In order to fix this : - Move the atomic_test_and_ *_mask inlines from asm-frv/atomic.h (why are they there at all anyway ? They are not touching atomic_t variables!) to asm-frv/bitops.h. Also fix a build issue with cmpxchg : it does not cast to (unsigned long *) like other architectures, to deal with it in the cmpxchg_local macro. FRV builds fine with this patch. Thanks to Adrian Bunk <bunk@kernel.org> for spotting this bug.

| * CRIS v32: Remove hwregs/timer_defs.h, it is now architecture specific.Jesper Nilsson2008-02-081-266/+0
| | | | | | | | - File is moved to arch-v32/mach-fs/hwregs/timer_defs.h
| * CRIS v32: Change drivers/i2c.c locking.Jesper Nilsson2008-02-081-49/+12
| | | | | | | | | | | | | | - 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 Nilsson2008-02-081-174/+174
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * CRIS v10: Cleanup of drivers/gpio.cJesper Nilsson2008-02-081-32/+29
| | | | | | | | | | | | | | | | | | | | | | - 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.
