Enabled Acer Launch Manager mode to disable the EC raw behavior for communication devices when WMID3 method available. And, we also add a ec_raw_mode kernel module option for enable The EC raw behavior mode when anyone what reset it back. When Acer Launch Manager mode enabled, EC will stop to touch any communication devices' RF state or power state that causes conflict with rfkill_input or any userland daemon to charge the rfkill rules.

The old code was using platform_driver.probe to initialize eeepc_wmi context. That's a mistake because if probe fail, eeepc_platform_register() won't tell anyone, and chaos will happen. Wrap add and remove code inside eeepc_wmi_add() / eeepc_wmi_remove(), and try to use the static platform_device only in eeepc_wmi_init() and eeepc_wmi_exit() The code is now very similar to eeepc-laptop, except eeepc_laptop_add and eeepc_laptop_remove are called from acpi_driver, not module init/exit functions, but WMI doesn't provide such functionalities (yet ?).

We don't need to call bios/acpi (cmpc_set_rfkill_wlan) if the blocked state is already set to the same value (little optimization). This can happen for example if we initialize the module with same initial hardware state (rfkill core always call cmpc_rfkill_block on initialization here). Also GWRI method only accepts 0 or 1 for setting rfkill block, as can be seen on AML code from acpidump->DSDT from a classmate sample I have, so should be fine setting state only to 0 or 1 directly.

WMI data blocks can contain WMI events with the same GUID but with different notifiy_ids, for example volume up/down hotkeys. This patch enables a single event handler to be registered and unregistered against all events with same GUID but different notify_ids. Since an event handler is passed the notify_id of an event it can can differentiate between the different events. The patch also ensures we only register and unregister a device per unique GUID.

The problem that this patch aims to fix is vfsmount refcounting scalability. We need to take a reference on the vfsmount for every successful path lookup, which often go to the same mount point. The fundamental difficulty is that a "simple" reference count can never be made scalable, because any time a reference is dropped, we must check whether that was the last reference. To do that requires communication with all other CPUs that may have taken a reference count. We can make refcounts more scalable in a couple of ways, involving keeping distributed counters, and checking for the global-zero condition less frequently. - check the global sum once every interval (this will delay zero detection for some interval, so it's probably a showstopper for vfsmounts). - keep a local count and only taking the global sum when local reaches 0 (this is difficult for vfsmounts, because we can't hold preempt off for the life of a reference, so a counter would need to be per-thread or tied strongly to a particular CPU which requires more locking). - keep a local difference of increments and decrements, which allows us to sum the total difference and hence find the refcount when summing all CPUs. Then, keep a single integer "long" refcount for slow and long lasting references, and only take the global sum of local counters when the long refcount is 0. This last scheme is what I implemented here. Attached mounts and process root and working directory references are "long" references, and everything else is a short reference. This allows scalable vfsmount references during path walking over mounted subtrees and unattached (lazy umounted) mounts with processes still running in them. This results in one fewer atomic op in the fastpath: mntget is now just a per-CPU inc, rather than an atomic inc; and mntput just requires a spinlock and non-atomic decrement in the common case. However code is otherwise bigger and heavier, so single threaded performance is basically a wash. Signed-off-by:Nick Piggin <npiggin@kernel.dk>
