2013-01-30samsung-laptop: Disable on EFI hardwareMatt Fleming
It has been reported that running this driver on some Samsung laptops with EFI can cause those machines to become bricked as detailed in the following report, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 There have also been reports of this driver causing Machine Check Exceptions on recent EFI-enabled Samsung laptops, https://bugzilla.kernel.org/show_bug.cgi?id=47121 So disable it if booting from EFI since this driver relies on grovelling around in the BIOS memory map which isn't going to work.

2013-01-30efi: Make 'efi_enabled' a function to query EFI facilitiesMatt Fleming
Originally 'efi_enabled' indicated whether a kernel was booted from EFI firmware. Over time its semantics have changed, and it now indicates whether or not we are booted on an EFI machine with bit-native firmware, e.g. 64-bit kernel with 64-bit firmware. The immediate motivation for this patch is the bug report at, https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557 which details how running a platform driver on an EFI machine that is designed to run under BIOS can cause the machine to become bricked. Also, the following report, https://bugzilla.kernel.org/show_bug.cgi?id=47121 details how running said driver can also cause Machine Check Exceptions. Drivers need a new means of detecting whether they're running on an EFI machine, as sadly the expression, if (!efi_enabled) hasn't been a sufficient condition for quite some time. Users actually want to query 'efi_enabled' for different reasons - what they really want access to is the list of available EFI facilities. For instance, the x86 reboot code needs to know whether it can invoke the ResetSystem() function provided by the EFI runtime services, while the ACPI OSL code wants to know whether the EFI config tables were mapped successfully. There are also checks in some of the platform driver code to simply see if they're running on an EFI machine (which would make it a bad idea to do BIOS-y things). This patch is a prereq for the samsung-laptop fix patch.

The second argument of ACPI driver .remove() operation is only used by the ACPI processor driver and the value passed to that driver through it is always available from the given struct acpi_device object's removal_type field. For this reason, the second ACPI driver .remove() argument is in fact useless, so drop it. Signed-off-by: Rafael J.

2013-01-07asus-laptop: Do not call HWRS on initBen Hutchings
Since commit 8871e99f89b7 ('asus-laptop: HRWS/HWRS typo'), module initialisation is very slow on the Asus UL30A. The HWRS method takes about 12 seconds to run, and subsequent initialisation also seems to be delayed. Since we don't really need the result, don't bother calling it on init. Those who are curious can still get the result through the 'infos' device attribute. Update the comment about HWRS in show_infos().

2012-10-02Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wqLinus Torvalds
Pull workqueue changes from Tejun Heo: "This is workqueue updates for v3.7-rc1. A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts.

2012-09-13apple-gmux: Fix index read functionsBernhard Froemel
Study of Apple's binary driver revealed that the GMUX_READ_PORT should be written between calls to gmux_index_wait_ready and gmux_index_wait_complete (i.e., the new index protocol must be followed). If this is not done correctly, the indexed gmux device only partially accepts writes which lead to problems concerning GPU switching.

2012-08-17asus-wmi: record wlan status while controlled by userappAceLan Kao
If the user bit is set, that mean BIOS can't set and record the wlan status, it will report the value read from id ASUS_WMI_DEVID_WLAN_LED (0x00010012) while we query the wlan status by id ASUS_WMI_DEVID_WLAN (0x00010011) through WMI. So, we have to record wlan status in id ASUS_WMI_DEVID_WLAN_LED (0x00010012) while setting the wlan status through WMI. This is also the behavior that windows app will do. Quote from ASUS application engineer === When you call WMIMethod(DSTS, 0x00010011) to get WLAN status, it may return (1) 0x00050001 (On) (2) 0x00050000 (Off) (3) 0x00030001 (On) (4) 0x00030000 (Off) (5) 0x00000002 (Unknown) (1), (2) means that the model has hardware GPIO for WLAN, you can call WMIMethod(DEVS, 0x00010011, 1 or 0) to turn WLAN on/off. (3), (4) means that the model doesn’t have hardware GPIO, you need to use API or driver library to turn WLAN on/off, and call WMIMethod(DEVS, 0x00010012, 1 or 0) to set WLAN LED status. After you set WLAN LED status, you can see the WLAN status is changed with WMIMethod(DSTS, 0x00010011). Because the status is recorded lastly (ex: Windows), you can use it for synchronization. (5) means that the model doesn’t have WLAN device. WLAN is the ONLY special case with upper rule. For other device, like Bluetooth, you just need use WMIMethod(DSTS, 0x00010013) to get, and WMIMethod(DEVS, 0x00010013, 1 or 0) to set. === Signed-off-by: AceLan Kao <acelan.kao@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
