2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

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.

2007-05-01i2c: Shrink struct i2c_clientDavid Brownell
This shrinks the size of "struct i2c_client" by 40 bytes: - Substantially shrinks the string used to identify the chip type - The "flags" don't need to be so big - Removes some internal padding It also adds kerneldoc for that struct, explaining how "name" is really a chip type identifier; it's otherwise potentially confusing. Because the I2C_NAME_SIZE symbol was abused for both i2c_client.name and for i2c_adapter.name, this needed to affect i2c_adapter too. The adapters which used that symbol now use the more-obviously-correct idiom of taking the size of that field. JD: Shorten i2c_adapter.name from 50 to 48 bytes while we're here, to avoid wasting space in padding.

The code was testing an 8-bit address against a 7-bit address. Will the confusion of the two never cease? Biggest flaw of the I2C protocol: the R/W bit is the LSB instead of the MSB. No one can ever agree if addresses are 7-bits and the R/W bit follows them, or if they are 8-bit and the R/W bit is OR-ed into the address byte. If the R/W bit was first, it wouldn't make any difference! Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

But this list is traversed by: for (i = 0, dvb_cards = card_list; i < ARRAY_SIZE(card_list); i++, dvb_cards++) { ... } in bt878_probe(). So this loop checks dummy sentinel entry, too.

2007-04-27V4L/DVB (5517): Usbvision: store the device database more efficientlyTrent Piepho
One bit wide bitfields need to declared unsigned to have the range 0 to 1, or they have the range -1 to 0. A few techniques to reduce the driver's size by about 1700 bytes on ia32, probably more on x86-64. Put the biggest fields first, less padding is necessary that way. Put fields with a limited range into a smaller type. For example VideoChannels will fit in 3 bits, and TunerType can use 8 bits. Vin_Reg1, Vin_Reg2, and Dvi_yuv define values for 8-bit registers, but they can't just go into an 8-bit field with no changes, since -1 was used as a flag to indicate a value was not present. So what we do is create a one-bit flag for each one to indicate if a value is or is not present. This only takes 9 bits and has the added advantage that when the register isn't overridden (Vin_Reg[12] never are) it doesn't need to appear in the structure definition since the default value for the flag will be zero.
