2008-07-24PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi
On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

2008-07-21device create: dvb: convert device_create to device_create_drvdataGreg Kroah-Hartman
device_create() is race-prone, so use the race-free device_create_drvdata() instead as device_create() is going away. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

However, as this symbol is used only on saa7134, there's no sense on keeping it defined there (or on ir-commons). So, let's move it to saa7134 and remove one symbol for being exported.

Declare all these devices, so that board drivers can tell which device is present, instead of always relying on auto-detection (which needs to write to the chip, eek!).

2008-07-20V4L/DVB (8341): videobuf: Add physically contiguous queue code V3Magnus Damm
This is V3 of the physically contiguous videobuf queues patch. Useful for hardware such as the SuperH Mobile CEU which doesn't support scatter gatter bus mastering. Since it may be difficult to allocate large chunks of physically contiguous memory after some uptime due to fragmentation, this code allocates memory using dma_alloc_coherent(). Architectures supporting dma_declare_coherent_memory() can easily avoid fragmentation issues by using dma_declare_coherent_memory() to force dma_alloc_coherent() to allocate from a certain pre-allocated memory area. Changes since V2 - use dma_handle for physical address - use "scatter gather" instead of "scatter gatter" Changes since V1: - use dev_err() instead of pr_err() - remember size in struct videobuf_dma_contig_memory - keep struct videobuf_dma_contig_memory in .c file - let videobuf_to_dma_contig() return dma_addr_t - implement __videobuf_sync() - return statements, white space and other minor fixes Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
