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] include/media: move driver interface headers to a separate dir Let's not mix headers used by the core with those headers that are needed by some driver-specific interface header. The headers used on drivers were manually moved using: mkdir include/media/drv-intf/ git mv include/media/cx2341x.h include/media/cx25840.h \ include/media/exynos-fimc.h include/media/msp3400.h \ include/media/s3c_camif.h include/media/saa7146.h \ include/media/saa7146_vv.h include/media/sh_mobile_ceu.h \ include/media/sh_mobile_csi2.h include/media/sh_vou.h \ include/media/si476x.h include/media/soc_mediabus.h \ include/media/tea575x.h include/media/drv-intf/ And the references for those headers were corrected using: MAIN_DIR="media/" PREV_DIR="media/" DIRS="drv-intf/" echo "Checking affected files" >&2 for i in $DIRS; do for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do n=`basename $j` git grep -l $n done done|sort|uniq >files && ( echo "Handling files..." >&2; echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

[media] cx231xx: fix crash after load/unload/load of module The following sequence of commands was triggering a kernel crash in cdev_get(): modprobe cx231xx rmmod cx231xx modprobe cx231xx v4l2grab -n 1 The problem was that cx231xx_usb_disconnect() was not doing anything because the test: if (!dev->udev) return; was reached (i.e, dev->udev was NULL). This is due to the fact that the 'dev' pointer placed as intfdata into the usb_interface structure had the wrong value, because cx231xx_probe() was doing the usb_set_intfdata() on the wrong usb_interface structure. For some reason, cx231xx_probe() was doing the following: static int cx231xx_usb_probe(struct usb_interface *interface, const struct usb_device_id *id) { struct usb_interface *lif = NULL; [...] /* store the current interface */ lif = interface; [...] /* store the interface 0 back */ lif = udev->actconfig->interface[0]; [...] usb_set_intfdata(lif, dev); [...] retval = v4l2_device_register(&interface->dev, &dev->v4l2_dev); [...] } So, the usb_set_intfdata() was done on udev->actconfig->interface[0] and not on the 'interface' passed as argument to the ->probe() and ->disconnect() hooks. Later on, v4l2_device_register() was initializing the intfdata of the correct usb_interface structure as a pointer to the v4l2_device structure. Upon unregistration, the ->disconnect() hook was getting the intfdata of the usb_interface passed as argument... and casted it to a 'struct cx231xx *' while it was in fact a 'struct v4l2_device *'. The correct fix seems to just be to set the intfdata on the proper interface from the beginning. Now, loading/unloading/reloading the driver allows to use the device properly.

USB: convert drivers/media/* to use module_usb_driver() This converts the drivers in drivers/media/* to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.
