include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

[media] stv090x: Don't use dynamic static allocation Dynamic static allocation is evil, as Kernel stack is too low, and compilation complains about it on some archs: drivers/media/dvb-frontends/stv090x.c:750:1: warning: 'stv090x_write_regs.constprop.6' uses dynamic stack allocation [enabled by default] Instead, let's enforce a limit for the buffer. Considering that I2C transfers are generally limited, and that devices used on USB has a max data length of 64 bytes for the control URBs. So, it seem safe to use 64 bytes as the hard limit for all those devices. On most cases, the limit is a way lower than that, but this limit is small enough to not affect the Kernel stack, and it is a no brain limit, as using smaller ones would require to either carefully each driver or to take a look on each datasheet.

V4L/DVB (13975): [STV090x] Added internal structure with shared settings and data. As the STV0900 features two demodulation paths in one chip there is some information used by both instances of the driver when used in dual mode. This information is now shared in an internal structure referenced by I2C adapter and address. Do initialisation of the demodulator only once when used in dual mode. Moved global mutex demod_lock to internal structure. Moved dev_ver and mclk to internal structure. Removed unused tuner_refclk from stv090x_state.

[media] stv090x: Don't use dynamic static allocation Dynamic static allocation is evil, as Kernel stack is too low, and compilation complains about it on some archs: drivers/media/dvb-frontends/stv090x.c:750:1: warning: 'stv090x_write_regs.constprop.6' uses dynamic stack allocation [enabled by default] Instead, let's enforce a limit for the buffer. Considering that I2C transfers are generally limited, and that devices used on USB has a max data length of 64 bytes for the control URBs. So, it seem safe to use 64 bytes as the hard limit for all those devices. On most cases, the limit is a way lower than that, but this limit is small enough to not affect the Kernel stack, and it is a no brain limit, as using smaller ones would require to either carefully each driver or to take a look on each datasheet.

V4L/DVB (13975): [STV090x] Added internal structure with shared settings and data. As the STV0900 features two demodulation paths in one chip there is some information used by both instances of the driver when used in dual mode. This information is now shared in an internal structure referenced by I2C adapter and address. Do initialisation of the demodulator only once when used in dual mode. Moved global mutex demod_lock to internal structure. Moved dev_ver and mclk to internal structure. Removed unused tuner_refclk from stv090x_state.

[media] stv090x: use lookup tables for carrier/noise ratio The stv090x driver uses the lookup table for signal strength already, with this patch we use the lookup tables for carrier/noise ratio as well. This has the advantage, that values for DVB-S and DVB-S2 are now corresponding, while before they were way off. The values are now proportional to real carrier/noise ratio, while before they were corresponding to register values. So now applications are able to give the user real carrier/noise ratio. Because the output has to be within 0x0000...0xFFFF the three negative values for DVB-S2 are omitted. This is no significant loss, because reception is lost at 7.5 dB already (TT S2-1600, Cine S2), so the negative values are not really important, and also for DVB-S they don´t exist.

[media] stv090x: make sleep/wakeup specific to the demod path The STV0900 features two demodulator paths in one chip. Thus it is not possible to use the generic power off function of the chip when sending one of them to standby. The other path will stop working in that case. The sleep function now switches off functionality specific to the demod path. The global stuff is only switched off, when both paths are in sleep mode. The wakeup function always turns on the global functionality and then works specific to the path.

[media] stv090x: make sleep/wakeup specific to the demod path The STV0900 features two demodulator paths in one chip.

The sleep function now switches off functionality specific to the demod path. The global stuff is only switched off, when both paths are in sleep mode.

[media] stv090x: remove export symbol for stv090x_set_gpio() Drivers that use dvb_attach can have just one exported symbol, or they will cause compilation breakages depending on the selected frontends. As Jim reported: drivers/built-in.o: In function `technisat_usb2_set_voltage': technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio' make: *** [vmlinux] Error 1 That happens because, on his configuration, the configuration is: CONFIG_DVB_USB=y CONFIG_DVB_STV090x=m Luis proposed ar way to fix, but that would just force the STV090x to be selected, even if one wants to use a device with a different frontend. Instead, let's do the right thing: move set_gpio to the configuration structure and fill it during dvb_attach(). This way, the driver can still call it, and dvb_attach() will load stv090x module only if the device really needs it.

However, the main problem is that universal frontends capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid frontends. So, convert everything to specify frontend frequencies in Hz.

i2c: Make remove callback return void The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

[media] stv090x: remove export symbol for stv090x_set_gpio() Drivers that use dvb_attach can have just one exported symbol, or they will cause compilation breakages depending on the selected frontends. As Jim reported: drivers/built-in.o: In function `technisat_usb2_set_voltage': technisat-usb2.c:(.text+0x3b4919): undefined reference to `stv090x_set_gpio' make: *** [vmlinux] Error 1 That happens because, on his configuration, the configuration is: CONFIG_DVB_USB=y CONFIG_DVB_STV090x=m Luis proposed ar way to fix, but that would just force the STV090x to be selected, even if one wants to use a device with a different frontend. Instead, let's do the right thing: move set_gpio to the configuration structure and fill it during dvb_attach(). This way, the driver can still call it, and dvb_attach() will load stv090x module only if the device really needs it.
