2014-05-23Merge tag 'usb-for-v3.16' of ↵Greg Kroah-Hartman6-0/+1004
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.16 merge window Not a lot here during this merge window. Mostly we just have the usual miscellaneous patches (removal of unnecessary prints, proper dependencies being added to Kconfig, build warning fixes, new device ID, etc. Other than those, the only important new features are the new support for OS Strings which should help Linux Gadget Drivers behave better under MS Windows. Also Babble Recovery implementation for MUSB on AM335x. Lastly, we also have ARCH_QCOM PHY support though phy-msm.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu Pull RCU updates from Paul E. McKenney: " 1. Update RCU documentation. These were posted to LKML at https://lkml.org/lkml/2014/4/28/634. 2. Miscellaneous fixes. These were posted to LKML at https://lkml.org/lkml/2014/4/28/645. 3. Torture-test changes. These were posted to LKML at https://lkml.org/lkml/2014/4/28/667. 4. Variable-name renaming cleanup, sent separately due to conflicts. This was posted to LKML at https://lkml.org/lkml/2014/5/13/854. 5. Patch to suppress RCU stall warnings while sysrq requests are being processed. This patch is the RCU portions of the patch that Rik posted to LKML at https://lkml.org/lkml/2014/4/29/457. The reason for pushing this patch ahead instead of waiting until 3.17 is that the NMI-based stack traces are messing up sysrq output, and in some cases also messing up the system as well."

2014-05-21perf tools: Add automatic remapping of Android librariesMichael Lentine1-1/+94
This patch automatically adjusts the path of MMAP records associated with Android system libraries. The Android system is organized with system libraries found in /system/lib and user libraries in /data/app-lib. On the host system (not running Android), system libraries can be found in the downloaded NDK directory under ${NDK_ROOT}/platforms/${APP_PLATFORM}/arch-${ARCH}/usr/lib and the user libraries are installed under libs/${APP_ABI} within the apk build directory. This patch makes running the reporting tools possible on the host system using the libraries from the NDK.

2014-05-21perf report/tui: Fix a bug when --fields/sort is givenNamhyung Kim1-4/+1
The hists__filter_entries() function is called when down arrow key is pressed for navigating through the entries in TUI. It has a check for filtering out entries that have very small overhead (under min_pcnt). However it just assumed the entries are sorted by the overhead so when it saw such a small overheaded entry, it just stopped navigating as an optimization. But it's not true anymore due to new --fields and --sort optoin behavior and this case users cannot go down to a next entry if ther's an entry with small overhead in-between.

Until now the hpp and sort functions do similar jobs different ways. Since the sort functions converted/wrapped to hpp formats it can do the job in a uniform way. The perf_hpp__sort_list has a list of hpp formats to sort entries and the perf_hpp__list has a list of hpp formats to print output result. To have a backward compatibility, it automatically adds 'overhead' field in front of sort list. And then all of fields in sort list added to the output list (if it's not already there).
