* acer-wmi: support for P key on TM8372Merlin Schumacher2012-12-031-0/+1
| | | | | | | | | | | | | | | | commit 67e1d34cd54cbf33f093f1dd53e7bda1124eb972 upstream. BugLink: http://launchpad.net/bugs/865807 There is no entry for P key on TM8372, so when P key is pressed, only "acer_wmi: Unknown key number - 0x29" in dmesg.

* acer-wmi: No wifi rfkill on Lenovo machinesIke Panhc2012-03-191-1/+29
| | | | | | | | | | | | | | | | | | | | | commit 461e74377cfcfc2c0d6bbdfa8fc5fbc21b052c2a upstream. We have several reports which says acer-wmi is loaded on ideapads and register rfkill for wifi which can not be unblocked. Since ideapad-laptop also register rfkill for wifi and it works reliably, it will be fine acer-wmi is not going to register rfkill for wifi once VPC2004 is found. Also put IBM0068/LEN0068 in the list. Though thinkpad_acpi has no wifi rfkill capability, there are reports which says acer-wmi also block wireless on Thinkpad E520/E420.

* acer-wmi: Only update rfkill status for associated hotkey eventsSeth Forshee2011-07-071-15/+26
| | | | | | | | | | | | acer-wmi is indiscriminately using the device state from hotkey events to update the various rfkill states. On the Aspire 1830 this can result in a soft block on the wlan when the touchpad hotkey is pressed, as it is reporting a non-zero device state that does not reflect the wireless status. To fix this, only update rfkill states when a wlan or bluetooth hotkey is pressed. Signed-off-by: Seth Forshee <seth.forshee@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

* acer-wmi: does not poll device status when WMI event is availableLee, Chun-Yi2011-03-281-2/+18
| | | | | | | | | | | | | | | | | | | | | Acer WMI hotkey event's result include current device status, just need sync the status to killswitch after acer-wmi driver receive hotkey event but not always poll device status. This is good for performance. But, if use EC raw mode, Acer BIOS will not emit wmi event and leave EC to control device status. So, still startup polling job when doesn't detect WMI event GUID or user choice to use ec_raw_mode. Tested on Acer TravelMate 8572 notebook.

* acer-wmi: does not set persistence state by rfkill_init_sw_stateLee, Chun-Yi2011-03-281-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | Acer BIOS keeps devices state when system reboot, but reset to default device states (Wlan on, Bluetooth off, wwan on) if system cold boot. That means BIOS's initial state is not always real persistence. So, removed rfkill_init_sw_state because it sets initial state to persistence then replicate to other new killswitch when rfkill-input enabled. After removed it, acer-wmi set initial soft-block state after rfkill register, and doesn't allow set_block until rfkill initial finished.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Input: libps2 - additional locking for i8042 portsDmitry Torokhov2009-09-171-0/+2
| | | | | | | | | | | | | | | | | The serio ports on i8042 are not completely isolated; while we provide enough locking to ensure proper serialization when accessing control and data registers AUX and KBD ports can still have an effect on each other on PS/2 protocol level. The most prominent effect is that issuing a command for the device connected to one port may cause abort of the command currently executing by the device connected to another port. Since i8042 nor serio subsystem are not aware of the details of the PS/2 protocol (length of the commands and their replies and so on) the locking should be done on libps2 level by adding special handling when we see that we are dealing with serio port on i8042.

* rfkill: remove set_global_sw_stateAlan Jenkins2009-06-101-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | rfkill_set_global_sw_state() (previously rfkill_set_default()) will no longer be exported by the rewritten rfkill core. Instead, platform drivers which can provide persistent soft-rfkill state across power-down/reboot should indicate their initial state by calling rfkill_set_sw_state() before registration. Otherwise, they will be initialized to a default value during registration by a set_block call. We remove existing calls to rfkill_set_sw_state() which happen before registration, since these had no effect in the old model. If these drivers do have persistent state, the calls can be put back (subject to testing :-). This affects hp-wmi and acer-wmi. Drivers with persistent state will affect the global state only if rfkill-input is enabled. This is required, otherwise booting with wireless soft-blocked and pressing the wireless-toggle key once would have no apparent effect. This special case will be removed in future along with rfkill-input, in favour of a more flexible userspace daemon (see Documentation/feature-removal-schedule.txt). Now rfkill_global_states[n].def is only used to preserve global states over EPO, it is renamed to ".sav".
