Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

User visible changes:

  - Add support for using several Intel PT features (CYC, MTC packets), the
    relevant documentation was updated: tools/perf/Documentation/intel-pt.txt,
    briefly describing those packets, its purposes, how to configure them in
    the event config terms and relevant external documentation for further
    reading. (Adrian Hunter)

  - Introduce support for probing at an absolute address, for user and kernel
    'perf probe's, useful when one have the symbol maps on a developer machine
    but not on an embedded system. (Wang Nan)

  - Fix 'perf probe' list results when a symbol can't be found or the
    address is zero and when an offset is provided without a function (Wang Nan)

  - Do not print '0x (null)' in uprobes when offset is zero (Wang Nan)

  - Clear the progress bar at the end of a ordered_events flush, fixing
    an UI artifact when, after ordering the events the screen doesn't get
    completely redraw, for instance, when an error window covers just the
    center of the screen and waits for user input. (Arnaldo Carvalho de Melo)

  - Fix 'annotate' segfault by resetting the dso find_symbol cache when removing
    symbols. (Arnaldo Carvalho de Melo)

Infrastructure changes:

  - Allow duplicate objects in the object list, just like it is possible to have
    things like this, in the kernel:

      drivers/Makefile:obj-$(CONFIG_PCI)        += usb/
      drivers/Makefile:obj-$(CONFIG_USB_GADGET) += usb/

    (Jiri Olsa)

  - Fix Intel PT 'instructions' sample period. (Adrian Hunter)

  - Prevent segfault when reading probe point with absolute address. (Wang Nan)

Build fixes:

  - Fix tarball build broken by pt/bts. (Adrian Hunter)

  - Remove export.h from MANIFEST, fixing the perf tarball make target. (Jiri Olsa)
