Pull tracing fixes from Steven Rostedt:

 - Fix error output of boot instance creation failure

   Currently if a boot instance creation fails, instead of printing out
   the name of the instance that failed, it prints "(null)". That is
   because it prints "cur_str" that had already been processed by
   strsep(). Print the saved name instead.

   While at it, print the error code of the failure.

 - Fix use-after-free for same named historgrams

   Histograms can be named so that they can be used in multiple events.
   But if the named histogram has a variable attached, the second event
   that uses the named histogram which duplicates it and needs to free
   the original after duplication leaves the old variable in place and
   still visible. If another histogram uses than variable, it will use
   the stale one which will try to reference the freed duplicate
   histogram and crash the kernel.

   Free the duplicate variables along with the duplicated histogram
   data.

 - Check return value of kthread_run() in event self test

   The events self tests uses a kthread for testing but does not check
   if it succeeded in creating a kthread. If the kthread creation were
   to fail, the code will still try to call kthread_stop() on the error
   returned.

 - Fix race between reading trace_pipe and updating subbuffer size

   If a user is reading the trace_pipe file at the same time they update
   the ring buffer sub-buffer size, can cause the trace_pipe read to
   read stale data. Add trace_access_lock() around updating the ring
   buffer sub-buffer size.

 - Fix eventfs_inode on failure path in creation of the events directory

   In the creation of the "events" directory, if after allocating the
   eventfs_inode a failure is detected, it calls cleanup_ei() which
   calls free_ei(). The free_ei() will test if eventfs_inode being freed
   has no children. It is a bug if it does. But on the failure case of
   the creation of the "events" directory, the children lists have not
   yet been initialized and the free will trigger a warning because
   list_empty() on an uninitialized list returns false.

   Move the initialization into init_ei() where it makes more sense and
   makes sure that a created eventfs_inode has its lists initialized
   upon creation.

 - Check return value of kthread_run() in ftrace direct sample code

   The sample code that shows how to use the ftrace direct calls does
   not test the return of kthread_run() to see if it succeeds. Return a
   failure if the kthread_run() doesn't succeed.

 - Clear user events state on fork in case of alloc failure

   On fork, the child gets a pointer to the parent's user events state.
   It makes a copy of it then updates the child's pointer to it. But if
   the allocation fails, the duplication function leaves the child with
   a pointer to its parent's descriptor. When the child cleans up its
   data, it will free the parent's descriptor while the parent is still
   using it.

   In the duplication function, set the child's user_event_mm to NULL
   before testing if the allocation succeeded, and when it exits it will
   not free the parent's descriptor.

 - Fix retry exhaustion in simple ring buffer reader swap

   simple_ring_buffer_swap_reader_page() starts with retry set to 8 and
   post-decrements it only after a failed link replacement. On the final
   attempt, a successful replacement leaves retry at zero, while a
   failed replacement leaves it at -1.

   But the check for success expects the retry value to be non-zero and
   exits with an error on zero. This is the opposite result. Fix it.

 - Fail nicely when the remote swap_reader_page() returns an error

   Currently, if the swap_reader_page() of a remote buffer fails, it
   triggers a WARN_ON_ONCE() and continues normally. Instead, have it
   exit with an error and a pr_warn() print instead of a full WARNING.

+ *  Version 2.2.0 Copyright (c) 2004 Torrey Hoffman <thoffman@arnor.net>
+ *  Version 2.1.1 Copyright (c) 2002 Vladimir Dergachev
+ *
+ *  This 2.2.0 version is a rewrite / cleanup of the 2.1.1 driver, including
+ *  porting to the 2.6 kernel interfaces, along with other modification
+ *  to better match the style of the existing usb/input drivers.  However, the
+ *  protocol and hardware handling is essentially unchanged from 2.1.1.
+ *
+ *  The 2.1.1 driver was derived from the usbati_remote and usbkbd drivers by
+ *  Vojtech Pavlik.
+ *
+ *  Changes:
+ *
+ *  Feb 2004: Torrey Hoffman <thoffman@arnor.net>
+ *            Version 2.2.0
+ *  Jun 2004: Torrey Hoffman <thoffman@arnor.net>
+ *            Version 2.2.1
+ *            Added key repeat support contributed by:
+ *                Vincent Vanackere <vanackere@lif.univ-mrs.fr>
+ *            Added support for the "Lola" remote contributed by:
+ *                Seth Cohn <sethcohn@yahoo.com>

+ * Hardware & software notes
+ *
+ * These remote controls are distributed by ATI as part of their
+ * "All-In-Wonder" video card packages.  The receiver self-identifies as a
+ * "USB Receiver" with manufacturer "X10 Wireless Technology Inc".
+ *
+ * The "Lola" remote is available from X10.  See:
+ *    http://www.x10.com/products/lola_sg1.htm
+ * The Lola is similar to the ATI remote but has no mouse support, and slightly
+ * different keys.
+ *
+ * It is possible to use multiple receivers and remotes on multiple computers
+ * simultaneously by configuring them to use specific channels.
+ *
+ * The RF protocol used by the remote supports 16 distinct channels, 1 to 16.
+ * Actually, it may even support more, at least in some revisions of the
+ * hardware.
+ *
+ * Each remote can be configured to transmit on one channel as follows:
+ *   - Press and hold the "hand icon" button.
+ *   - When the red LED starts to blink, let go of the "hand icon" button.
+ *   - When it stops blinking, input the channel code as two digits, from 01
+ *     to 16, and press the hand icon again.
+ *
+ * The timing can be a little tricky.  Try loading the module with debug=1
+ * to have the kernel print out messages about the remote control number
+ * and mask.  Note: debugging prints remote numbers as zero-based hexadecimal.
+ *
+ * The driver has a "channel_mask" parameter. This bitmask specifies which
+ * channels will be ignored by the module.  To mask out channels, just add
+ * all the 2^channel_number values together.
+ *
+ * For instance, set channel_mask = 2^4 = 16 (binary 10000) to make ati_remote
+ * ignore signals coming from remote controls transmitting on channel 4, but
+ * accept all other channels.
+ *
+ * Or, set channel_mask = 65533, (0xFFFD), and all channels except 1 will be
+ * ignored.
+ *
+ * The default is 0 (respond to all channels). Bit 0 and bits 17-32 of this
+ * parameter are unused.

+ * a port value in the 3 highest bits and a length value in the 5 lowest
+ * bits.
+ *
+ * The length field is overloaded, with a value of 11111 indicating that the
+ * following byte is a command or response code, and the length of the entire
+ * message is determined by the code. If the length field is not 11111, then
+ * it specifies the number of bytes of port data that follow.

+ * USB RedRat3 IR Transceiver rc-core driver
+ *
+ * Copyright (c) 2011 by Jarod Wilson <jarod@redhat.com>
+ *  based heavily on the work of Stephen Cox, with additional
+ *  help from RedRat Ltd.
+ *
+ * This driver began life based on an old version of the first-generation
+ * lirc_mceusb driver from the lirc 0.7.2 distribution. It was then
+ * significantly rewritten by Stephen Cox with the aid of RedRat Ltd's
+ * Chris Dodge.
+ *
+ * The driver was then ported to rc-core and significantly rewritten again,
+ * by Jarod, using the in-kernel mceusb driver as a guide, after an initial
+ * port effort was started by Stephen.
+ *
+ * TODO LIST:
+ * - fix lirc not showing repeats properly
+ * --
+ *
+ * The RedRat3 is a USB transceiver with both send & receive,
+ * with 2 separate sensors available for receive to enable
+ * both good long range reception for general use, and good
+ * short range reception when required for learning a signal.
+ *
+ * http://www.redrat.co.uk/
+ *
+ * It uses its own little protocol to communicate, the required
+ * parts of which are embedded within this driver.

+ *  winbond-cir.c - Driver for the Consumer IR functionality of Winbond
+ *                  SuperI/O chips.
+ *
+ *  Currently supports the Winbond WPCD376i chip (PNP id WEC1022), but
+ *  could probably support others (Winbond WEC102X, NatSemi, etc)
+ *  with minor modifications.

+ *
+ *  Dedicated to my daughter Matilda, without whose loving attention this
+ *  driver would have been finished in half the time and with a fraction
+ *  of the bugs.
+ *
+ *  Written using:
+ *    o Winbond WPCD376I datasheet helpfully provided by Jesse Barnes at Intel
+ *    o NatSemi PC87338/PC97338 datasheet (for the serial port stuff)
+ *    o DSDT dumps
+ *
+ *  Supported features:
+ *    o IR Receive
+ *    o IR Transmit
+ *    o Wake-On-CIR functionality
+ *    o Carrier detection
