Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC bug fixes from Arnd Bergmann:
"Things are calming down for arm-soc as well. This set of bug fixes is
dominated in size by the at91 platform bug fixes. Some of them were
meant to go through the framebuffer tree during the merge window, but
since the framebuffer maintainer could not be reached, I offered to
take them here. The other notable at91 change is the addition of
pinctrl definitions to fix the NAND controller.
The rest are mostly simple regression fixes:
- Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
renaming of the Kconfig symbol. You will get a trivial merge
conflict here, we still want to remove it.
- missing bits for clocks on imx and s5pv210
- missing header inclusions in mmp and shmobile
- typos in s5pv210 camera and vt8500 clock support code
and three trivial fixes for pre-3.8 bugs:
- an old bogus build warning in the joystick driver
- a misleading Kconfig description
- a NULL pointer check on davinci"

-Currently the ALPS touchpad driver supports four protocol versions in use by
-ALPS touchpads, called versions 1, 2, 3, and 4. Information about the various
-protocol versions is contained in the following sections.
+Since roughly mid-2010 several new ALPS touchpads have been released and
+integrated into a variety of laptops and netbooks. These new touchpads
+have enough behavior differences that the alps_model_data definition
+table, describing the properties of the different versions, is no longer
+adequate. The design choices were to re-define the alps_model_data
+table, with the risk of regression testing existing devices, or isolate
+the new devices outside of the alps_model_data table. The latter design
+choice was made. The new touchpad signatures are named: "Rushmore",
+"Pinnacle", and "Dolphin", which you will see in the alps.c code.
+For the purposes of this document, this group of ALPS touchpads will
+generically be called "new ALPS touchpads".
+
+We experimented with probing the ACPI interface _HID (Hardware ID)/_CID
+(Compatibility ID) definition as a way to uniquely identify the
+different ALPS variants but there did not appear to be a 1:1 mapping.
+In fact, it appeared to be an m:n mapping between the _HID and actual

+ 3.3 Multiqueue tuntap interface:
+
+ From version 3.8, Linux supports multiqueue tuntap which can uses multiple
+ file descriptors (queues) to parallelize packets sending or receiving. The
+ device allocation is the same as before, and if user wants to create multiple
+ queues, TUNSETIFF with the same device name must be called many times with
+ IFF_MULTI_QUEUE flag.
+
+ char *dev should be the name of the device, queues is the number of queues to
+ be created, fds is used to store and return the file descriptors (queues)
+ created to the caller. Each file descriptor were served as the interface of a
+ queue which could be accessed by userspace.
+
+ #include <linux/if.h>
+ #include <linux/if_tun.h>
+
+ int tun_alloc_mq(char *dev, int queues, int *fds)

+ /* Flags: IFF_TUN - TUN device (no Ethernet headers)
+ * IFF_TAP - TAP device
+ *
+ * IFF_NO_PI - Do not provide packet information
+ * IFF_MULTI_QUEUE - Create a queue of multiqueue device

+
+ A new ioctl(TUNSETQUEUE) were introduced to enable or disable a queue. When
+ calling it with IFF_DETACH_QUEUE flag, the queue were disabled. And when
+ calling it with IFF_ATTACH_QUEUE flag, the queue were enabled. The queue were
+ enabled by default after it was created through TUNSETIFF.

- This option will modify all the calls to ftrace dynamically

+ This option will modify all the calls to function tracing
+ dynamically (will patch them out of the binary image and
+ replace them with a No-Op instruction) on boot up. During
+ compile time, a table is made of all the locations that ftrace
+ can function trace, and this table is linked into the kernel
+ image. When this is enabled, functions can be individually
+ enabled, and the functions not enabled will not affect
+ performance of the system.
+
+ See the files in /sys/kernel/debug/tracing:
+ available_filter_functions
+ set_ftrace_filter
+ set_ftrace_notrace
This way a CONFIG_FUNCTION_TRACER kernel is slightly larger, but
otherwise has native performance as long as no tracing is active.
- The changes to the code are done by a kernel thread that
- wakes up once a second and checks to see if any ftrace calls
- were made. If so, it runs stop_machine (stops all CPUS)
- and modifies the code to jump over the call to ftrace.
