ACPI / video: Revert native brightness quirk for ThinkPad T530

2014-06-07T17:28:27+00:00

commit 07d1d29ee1e194b932328ad2dc1d40297062ab7f upstream.

Seems it helps some users, but causes issues for other users:
https://bugzilla.redhat.com/show_bug.cgi?id=1089545

So lets drop it for now until we've figured out a better fix.

ACPI / video: correct DMI tag for Dell Inspiron 7520

2014-06-07T17:28:27+00:00

commit 5ff365fb6aed4c7ee5aae7b0239ce0b514aefabc upstream.

The DMI tag used to identify Dell Inspiron 7520 should be product name
instead of product version.

ACPI: blacklist win8 OSI for Dell Inspiron 7737

2014-06-07T17:28:26+00:00

commit b753631b3576bf343151a82513c5d56fcda1e24f upstream.

With win8 capabiltiy, the machine will boot itself immediately after
shutdown command has executed.

Work around this issue by disabling win8 capcability.  This workaround
also makes wireless hotkey work.

ACPI / processor: do not mark present at boot but not onlined CPU as onlined

2014-06-07T17:28:26+00:00

commit 0b9d46dd7debf8e6dc8614106f1c1909fa8de64d upstream.

acpi_processor_add() assumes that present at boot CPUs
are always onlined, it is not so if a CPU failed to become
onlined. As result acpi_processor_add() will mark such CPU
device as onlined in sysfs and following attempts to
online/offline it using /sys/device/system/cpu/cpuX/online
attribute will fail.

Do not poke into device internals in acpi_processor_add()
and touch "struct device { .offline }" attribute, since
for CPUs onlined at boot it's set by:
  topology_init() -> arch_register_cpu() -> register_cpu()
before ACPI device tree is parsed, and for hotplugged
CPUs it's set when userspace onlines CPU via sysfs.

ACPI / blacklist: Add dmi_enable_osi_linux quirk for Asus EEE PC 1015PX

2014-06-07T17:28:26+00:00

commit f6e6e1b9fee88c90586787b71dc49bb3ce62bb89 upstream.

Without this this EEE PC exports a non working WMI interface, with this it
exports a working "good old" eeepc_laptop interface, fixing brightness control
not working as well as rfkill being stuck in a permanent wireless blocked
state.

This is not an ideal way to fix this, but various attempts to fix this
otherwise have failed, see:
