module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.Acked-by: Mauro Carvalho Chehab

This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c

who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.Signed-off-by: Greg Kroah-Hartman

The Satellite C670-10V generates notifications for hotkeys but does
not support HCI_SYSTEM_EVENT. As a result when a hotkey is pressed
it gets stuck in an infinite loop in toshiba_acpi_notify. To fix
this, detect whether or not HCI_SYSTEM_EVENT is supported up-front
and don't try to read system events if it isn't supported. In
addition, limit the number of retries when reading HCI_SYSTEM_EVENT
fails so that this loop cannot run unbounded.Signed-off-by: Seth Forshee

Writeback and thinkpad_acpi have been using thaw_process() to prevent
deadlock between the freezer and kthread_stop(); unfortunately, this
is inherently racy - nothing prevents freezing from happening between
thaw_process() and kthread_stop().This patch implements kthread_freezable_should_stop() which enters
refrigerator if necessary but is guaranteed to return if
kthread_stop() is invoked. Both thaw_process() users are converted to
use the new function.Note that this deadlock condition exists for many of freezable
kthreads. They need to be converted to use the new should_stop or
freezable workqueue.Tested with synthetic test case.

RSP>From my POV, it looks like the hardware is not working as expected
and returns a bogus data rate. The driver doesn't check the result
and directly uses it as some sort of divisor in some places:msleep(lis3->pwron_delay / lis3lv02d_get_odr());
Under this circumstances, this could very well cause the
"divide by zero" exception from above.For now, I fixed it the easiest and most obvious way:
Check if the result is sane and if it isn't use a sane default
instead. I went for "100" in the latter case, simply because
/sys/devices/platform/lis3lv02d/rate returns it on a successful
boot.Signed-off-by: Christian Lamparter

There have new acer notebooks' BIOS provide new WMID_GUID3 and

more machines were already removed old wmi methods from DSDT.So, this patch add a new ACER_WMID_v2 interface flag to represent
new acer notebooks, the following is definition:+ ACER_WMID:
It means this machine only provides WMID_GUID1/2 methods.+ ACER_WMID_v2:
It means this machine provide new WMID_GUID3 and WMID_EVENT_GUID
methods.
Some ACER_WMID_v2 machines also provide old WMID_GUID1/2 methods,
but we still query/set communication device's state by new
WMID_GUID3 method.Tested on Acer Travelmate 8572

Add three new rfkill switches in this driver that are specific to

Please note that you might not need all three switches. For example if
you don't have a 3G module inside your tablet.Also, on my device, the gpio for the wifi/bt module is connected to the
bluetooth line. Therefore to activate your wireless lan interface, you
need to use the "pega-bt" rfkill switch.Finally, the rfkill switch only works before the wireless module is
