Subject: [GIT PULL 00/22] perf/core improvements and fixes
Hi Ingo,
Please consider pulling, this replaces the previous perf-core-for-mingo
pull req, replacing the last patch in that series and adding a few more fixes from
Jiri and Wang,
Thanks,
- Arnaldo

tracing/uprobes: Do not print '0x (null)' when offset is 0 (2015-08-26 10:43:01 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- 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:
- Allow duplicate objects in the object list, just like it is possible to have
things like this, in the kernel: (Jiri Olsa)
drivers/Makefile:obj-$(CONFIG_PCI) += usb/
drivers/Makefile:obj-$(CONFIG_USB_GADGET) += usb/
- 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)
