| * ACPI dock: move some functions to .init.textUwe Kleine-König2010-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | find_dock and find_bay are only called by dock_init which lives in .init.text dock_add is only called by find_dock and find_bay. So all three functions can be moved to .init.text, too. This fixes: WARNING: vmlinux.o(.text+0x2134b7): Section mismatch in reference from the function dock_add() to the function .init.text:platform_device_register_resndata() The function dock_add() references the function __init platform_device_register_resndata(). This is often because dock_add lacks a __init annotation or the annotation of platform_device_register_resndata is wrong. for a build with unset CONFIG_MODULES.

* | ACPI / ACPICA: Defer enabling of runtime GPEs (v3)Rafael J. Wysocki2010-09-24
|/ | | | | | | | | | | | | | | | The current ACPI GPEs initialization code has a problem that it enables some GPEs pointed to by device _PRW methods, generally intended for signaling wakeup events (system or device wakeup). These GPEs are then almost immediately disabled by the ACPI namespace scanning code with the help of acpi_gpe_can_wake(), but it would be better not to enable them at all until really necessary. Modify the initialization of GPEs so that the ones that have associated _Lxx or _Exx methods and are not pointed to by any _PRW methods will be enabled after the namespace scan is complete.

| * include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ACPI: dock: properly initialize local struct dock_station in dock_add()Alex Chiang2010-02-16
|/ | | | | | | | | | | | | | | | | | | | | | Commit fe06fba2 (ACPI: dock: add struct dock_station * directly to platform device data) changed dock_add() to use the platform_device_register_data() API. We passed that interface a stack variable, which is kmemdup'ed and assigned to the device's platform_data pointer. Unfortunately, whatever random garbage is in the stack variable gets coped during the kmemdup, and that leads to broken behavior. Explicitly zero out the structure before passing it to the API.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements uevent suppress in kobject and removes it from struct device, based on the following ideas: 1,Uevent sending should be one attribute of kobject, so suppressing it in kobject layer is more natural than in device layer. By this way, we can do it for other objects embedded with kobject. 2,It may save several bytes for each instance of struct device.(On my omap3(32bit ARM) based box, can save 8bytes per device object) This patch also introduces dev_set|get_uevent_suppress() helpers to set and query uevent_suppress attribute in case to help kobject as private part of struct device in future.

If an undock is processed, the dock driver sends a uevent and userspace might read the show_docked property in sysfs. This causes an evaluation of _STA of the particular device which causes the dock driver to immediately dock again.
