It also alters the definition of SOFT_RST_OFF from (0 << 31) to ~SOFT_RST_ON (= ~(1 << 31)). The former seems bogus. The latter is consistent with the code in sh_mmcif_boot_init().

This is not always enough; a tablet and a touchscreen may emit exactly the same data, for instance, but the former should be set up with a pointer whereas the latter does not need to. Recently, a new type of touchpad has emerged where the buttons are under the pad, which changes logic without changing the emitted data. This patch introduces a new ioctl, EVIOCGPROP, which enables user access to a set of device properties useful during setup. The properties are given as a bitmap in the same fashion as the event types, and are also made available via sysfs, uevent and /proc/bus/input/devices.

The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver. This patch moves all tracking event handling over to the input core, simplifying both the existing drivers and the ones currently in preparation.

Interrupt-driven FIFO operation is implemented. The hardware also supports pure register-based operation (which is slower) and DMA-based FIFO operation. As the FIFOs are only 16 bytes long, DMA operation is probably not worth the hassle. Signed-off-by: Alexey Charkov <alchark@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

One slightly awkward aspect of the conversion is that USB devices will now have two suspend-delay attributes: the old power/autosuspend file and the new power/autosuspend_delay_ms file. One expresses the delay time in seconds and the other in milliseconds, but otherwise they do the same thing. The old attribute can be deprecated and then removed eventually.

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>

So replace it with an open-coded byte comparison. This increases code size by 8 bytes in the critical __d_lookup_rcu function, but the speedup is huge, averaging 10 runs of each: git diff st user sys elapsed CPU before 1.15 2.57 3.82 97.1 after 1.14 2.35 3.61 96.8 git diff mt user sys elapsed CPU before 1.27 3.85 1.46 349 after 1.26 3.54 1.43 333 Elapsed time for single threaded git diff at 95.0% confidence: -0.21 +/- 0.01 -5.45% +/- 0.24% It's -0.66% +/- 0.06% elapsed time on my Opteron, so rep cmp costs on the fam10h seem to be relatively smaller, but there is still a win.
