2007-05-02PCI: Cleanup the includes of <linux/pci.h>Jean Delvare
I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining. Untested files are: arch/alpha/kernel/err_common.c arch/alpha/kernel/err_ev6.c arch/alpha/kernel/err_ev7.c arch/ia64/sn/kernel/huberror.c arch/ia64/sn/kernel/xpnet.c arch/m68knommu/kernel/dma.c arch/mips/lib/iomap.c arch/powerpc/platforms/pseries/ras.c arch/ppc/8260_io/enet.c arch/ppc/8260_io/fcc_enet.c arch/ppc/8xx_io/enet.c arch/ppc/syslib/ppc4xx_sgdma.c arch/sh64/mach-cayman/iomap.c arch/xtensa/kernel/xtensa_ksyms.c arch/xtensa/platform-iss/setup.c drivers/i2c/busses/i2c-at91.c drivers/i2c/busses/i2c-mpc.c drivers/media/video/saa711x.c drivers/misc/hdpuftrs/hdpu_cpustate.c drivers/misc/hdpuftrs/hdpu_nexus.c drivers/net/au1000_eth.c drivers/net/fec_8xx/fec_main.c drivers/net/fec_8xx/fec_mii.c drivers/net/fs_enet/fs_enet-main.c drivers/net/fs_enet/mac-fcc.c drivers/net/fs_enet/mac-fec.c drivers/net/fs_enet/mac-scc.c drivers/net/fs_enet/mii-bitbang.c drivers/net/fs_enet/mii-fec.c drivers/net/ibm_emac/ibm_emac_core.c drivers/net/lasi_82596.c drivers/parisc/hppb.c drivers/sbus/sbus.c drivers/video/g364fb.c drivers/video/platinumfb.c drivers/video/stifb.c drivers/video/valkyriefb.c include/asm-arm/arch-ixp4xx/dma.h sound/oss/au1550_ac97.c I would welcome test reports for these files. I am fine with removing the untested files from the patch if the general opinion is that these changes aren't safe. The tested part would still be nice to have.

2007-05-02[MTD] [NAND] Support multiple chips in CAFÉ driverDavid Woodhouse
The CAFÉ can handle two chip on separate chipselect lines. Hook up the undocumented chipselect bits in the driver and probe both. In the case of OLPC, it's not actually two separate devices -- it's a single '1GiB' package with two 512MiB dies internally. So clear the NAND_BBT_PERCHIP flag to treat it as a single chip for BBT purposes, and make life easier for the firmware. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2007-04-27[MTD] [NAND] Wrong calculation of page number in nand_block_bad()Knobloch, Thomas
In case that there is no memory based bad block table available the function nand_block_checkbad() in drivers/mtd/nand/nand_base.c will call nand_block_bad() directly. When parameter 'getchip' is set to zero, nand_block_bad() will not right shift the offset to calculate the correct page number.

2007-04-17[MTD] nandsim: enhance nandsim to allow arbitrary NAND sizeAdrian Hunter
A new module parameter has been added called 'overridesize', which overrides the size that would be determined by the ID bytes. 'overridesize' is specified in erase blocks and as the exponent of a power of two e.g. 5 means a size of 32 erase blocks.

2007-04-17[MTD] [NAND] Casting bug in nand_default_block_markbadAndre Renaud
There is a slight bug in nand_default_block_markbad, where the offset is cast to an integer, prior to being shifted. This means that on large offsets, it is incorrectly doing a signed shift & losing bits. Fixed this by doing the cast after the shift (as is done elsewhere in the code).

During the MTD rework the oobavail parameter of mtd_info structure has become private. This is not quite correct in terms of integrity and logic.

2006-11-28[MTD] [NAND] remove len/ooblen confusion.Vitaly Wool
As was discussed between Ricard Wanderlöf, David Woodhouse, Artem Bityutskiy and me, the current API for reading/writing OOB is confusing. The thing that introduces confusion is the need to specify ops.len together with ops.ooblen for reads/writes that concern only OOB not data area. So, ops.len is overloaded: when ops.datbuf != NULL it serves to specify the length of the data read, and when ops.datbuf == NULL, it serves to specify the full OOB read length. The patch inlined below is the slightly updated version of the previous patch serving the same purpose, but with the new Artem's comments taken into account. Artem, BTW, thanks a lot for your valuable input! Signed-off-by: Vitaly Wool <vwool@ru.mvista.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
