llist_add(new, head) can simply use llist_add_batch(new, new, head), no need to duplicate the code. This obviously uninlines llist_add() and to me this is a win. But we can make llist_add_batch() inline if this is desirable, in this case gcc can notice that new_first == new_last if the caller is llist_add().

1. This is mostly theoretical, but llist_add*() need ACCESS_ONCE(). Otherwise it is not guaranteed that the first cmpxchg() uses the same value for old_entry and new_last->next. 2. These helpers cache the result of cmpxchg() and read the initial value of head->first before the main loop. I do not think this makes sense. In the likely case cmpxchg() succeeds, otherwise it doesn't hurt to reload head->first. I think it would be better to simplify the code and simply read ->first before cmpxchg().

The file_lock_list is only used for /proc/locks. The vastly common case is for locks to be put onto the list and come off again, without ever being traversed. Help optimize for this use-case by moving to percpu hlist_head-s. At the same time, we can make the locking less contentious by moving to an lglock. When iterating over the lists for /proc/locks, we must take the global lock and then iterate over each CPU's list in turn. This change necessitates a new fl_link_cpu field to keep track of which CPU the entry is on. On x86_64 at least, this field is placed within an existing hole in the struct to avoid growing the size.

Intuos4 WL is separately reporting power supply and battery charging status - now hid-wacom is using that information. Previously hid-wacom was wrongly treating "battery charging" bit as "power supply connected". Now it should report battery charging, battery discharging, battery full and power supply status. Intuos4 WL sends reports when is in use (obvious) and when unplugging power supply. If means that if the device is being charged, but it's not being used it will never report "battery full". The same problem happens after the device has been connected, but it's not in use - the battery/ac status will be incorrect. Currently there is no mechanism to ask the device to send a report containing battery/ac status. Signed-off-by: NPrzemo Firszt <przemo@firszt.eu> Signed-off-by: NJiri Kosina <jkosina@suse.cz>

The current i2c hid driver does not support sending HID output reports using the output register for devices which support receiving reports through this method. This patch determines which method to use to send output reports based on the value of wMaxOutputLength in the device's HID descriptor.
