    "We've been sitting on our fixes branch for a while, so this batch is
    unfortunately on the large side.

    A lot of these are tweaks and fixes to device trees, fixing various
    bugs around clocks, reg ranges, etc. There's also a few defconfig
    updates (which are on the late side, no more of those).

    All in all the diffstat is bigger than ideal at this time, but nothing
    in here seems particularly risky"

  • This reverts commit da788acb28386aa896224e784954bb73c99ff26c.

    That commit tried to fix the section mismatch warning by moving the
    ppc_corenet_clk_driver struct to init section. This is definitely wrong
    because the kernel would free the memories occupied by this struct
    after boot while this driver is still registered in the driver core.
    The kernel would panic when accessing this driver struct.

    Renesas ARM Based SoC Fixes for v3.19

    This pull request is based on the last round of SoC updates for v3.19,
    Fourth Round of Renesas ARM Based SoC Updates for v3.19, tagged as
    renesas-soc3-for-v3.19, merged into your next/soc branch and included in
    v3.19-rc1.

    - ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds

    Set .control_parent for all irqpin instances for sh73a0 SoC when booting
    using legacy C.

    - ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds

    This fixes a long standing problem which has been present since
    the sh73a0 SoC started using the INTC External IRQ pin driver.

    The patch that introduced the problem is 341eb5465f67437a ("ARM:
    shmobile: INTC External IRQ pin driver on sh73a0") which was included
    in v3.10.

  • The arndale-octa board was giving "imprecise external aborts" during
    boot-up with MCPM enabled. CCI enablement of the boot cluster was found
    to be the cause of these aborts (possibly because the secure f/w was not
    allowing it). Hence, disable CCI for the arndale-octa board.

  • rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
    settings depending on the card state. This collides with a lot of assumptions.

    It only works when using the internal card-detect mechanism and breaks
    horribly when using either the normal card-detect via the slot-gpio function
    or via any other pin. Also there is of course no link between the mmc and jtag
    on the software-side, so the jtag clocks may very well be disabled when the
    card is ejected and the soc switches back to the jtag pinmux.

    Leaving the switching function enabled did result in mmc timeouts and rcu
    stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
    as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
    anyway.

  • Currently the symbol structure is allocated with symbol_conf.priv_size
    to carry sideband information like annotation, map browser on TUI and
    sort-by-name tree node. So retrieving these information from symbol
    needs to care about the details of such placement.

    However the annotation code just assumes that the symbol is placed after
    the struct annotation. But actually there's other info between them.
    So accessing those struct will lead to an undefined behavior (usually a
    crash) after they write their info to the same location.

    To reproduce the problem, please follow the steps below:

    1. run perf report (TUI of course) with -v option
    2. open map browser (by pressing right arrow key for any entry)
    3. search any function (by pressing '/' key and input whatever..)
    4. return to the hist browser (by pressing 'q' or left arrow key)
    5. open annotation window for the same entry (by pressing 'a' key)

  • Perf tool fails to unwind user stack if the event raises in a shared
    object. This patch improves tests/dwarf-unwind.c to demonstrate the
    problem by utilizing commonly used glibc function "bsearch". If perf is
    not statically linked, the testcase will try to unwind a mixed call
    trace.

    By debugging libunwind I found that there is a bug in unwind-libunwind:
    it always passes 0 as segbase to libunwind, cause libunwind unable to
    locate debug_frame entry fir first level ip address (I add some more
    debugging output into libunwind to make things clear):

    >_Uarm_dwarf_find_debug_frame: start_ip = 10be98, end_ip = 10c2a4
    >_Uarm_dwarf_find_debug_frame: found debug_frame table `/lib/libc-2.18.so': segbase=0x0, len=7, gp=0x0, table_data=0x449388
    >_Uarm_dwarf_search_unwind_table: call lookup:ip = b6cd3bcc, segbase = 0, rel_ip = b6cd3bcc
    >lookup: e->start_ip_offset = bcf18 (rel_ip = b6cd3bcc)
    >lookup: e->start_ip_offset = 6d314 (rel_ip = b6cd3bcc)
    >lookup: e->start_ip_offset = 33d0c (rel_ip = b6cd3bcc)
    ...
    >lookup: e->start_ip_offset = 15d0c (rel_ip = b6cd3bcc)
    >lookup: e->start_ip_offset = 15c40 (rel_ip = b6cd3bcc)

    >put_rs_cache: unmasking signals/interrupts and releasing lock
    >_Uarm_dwarf_step: returning -10
    >_Uarm_step: dwarf_step()=-10

    This patch passes map->start as segbase to dwarf_find_debug_frame(), so
    di will be initialized correctly.

    In addition, dso and executable are different when setting segbase. This
    patch first check whether the elf is executable, and pass segbase only
    for shared object.

  • We need to use lib/hweight.c for that, just like we do for lib/rbtree.c,
    so tools need to link hweight.o. For now do it directly, but we need to
    have a tools/lib/lk.a or .so that collects these goodies...

  • When thread__init_map_groups() fails, a new thread should be removed
    from the rbtree since it's gonna be freed. Also update last match cache
    only if the function succeeded.

  • When build with 'make ARCH=x86' and dwarf unwind is on, there is a
    compiling error:

    CC /home/wn/perf/arch/x86/util/unwind-libdw.o
    CC /home/wn/perf/arch/x86/tests/regs_load.o
    arch/x86/tests/regs_load.S: Assembler messages:
    arch/x86/tests/regs_load.S:65: Error: operand type mismatch for `push'
    arch/x86/tests/regs_load.S:72: Error: operand type mismatch for `pop'
    make[1]: *** [/home/wn/perf/arch/x86/tests/regs_load.o] Error 1
    make[1]: INTERNAL: Exiting with 25 jobserver tokens available; should be 24!
    make: *** [all] Error 2
    ...

    Which is caused by incorrectly undefine macro HAVE_ARCH_X86_64_SUPPORT.
    'config/Makefile.arch' tests __x86_64__ only when 'ARCH=x86_64'.
    However, when building x86_64 kernel, ARCH=x86 is valid and commonly
    used. Build systems, such as yocto, uses x86_64 compiler with 'ARCH=x86'
    to build x86_64 perf, which causes mismatching.

    As __LP64__ is defined for x86_64 as well, we can consolidate the
    __x86_64__ check to the __LP64__ check and get rid of the IS_X86_64
    IMHO.

    (This patch is made by Namhyung Kim when replying my v1 patch:

    https://lkml.org/lkml/2015/1/7/17

    I modified the code to remove dependency on RAW_ARCH:

    https://lkml.org/lkml/2015/1/7/865

    Namhyung Kim didn't provide his SOB in his original email. I add
    mine only for my modification.)

  • When it failed to write probe commands to the probe_event file in
    debugfs, it needs to propagate the error code properly. Current code
    blindly uses the return value of the write(2) so it always uses
    -1 (-EPERM) and it might confuse users.
