       "Fix s390 breakage from sorting mcount tables.
      
        The latest merge of the tracing tree sorts the mcount table at build
        time. But s390 appears to do things differently (like always) and
        replaces the sorted table back to the original unsorted one. As the
        ftrace algorithm depends on it being sorted, bad things happen when it
        is not, and s390 experienced those bad things.
      
        Add a new config to tell the boot if the mcount table is sorted or
        not, and allow s390 to opt out of it"

      ftrace: Fix assuming build time sort works for s390 · 6b9b6413
      Steven Rostedt (Google) authored
      To speed up the boot process, as mcount_loc needs to be sorted for ftrace
      to work properly, sorting it at build time is more efficient than boot up
      and can save milliseconds of time. Unfortunately, this change broke s390
      as it will modify the mcount_loc location after the sorting takes place
      and will put back the unsorted locations. Since the sorting is skipped at
      boot up if it is believed that it was sorted at run time, ftrace can crash
      as its algorithms are dependent on the list being sorted.
      
      Add a new config BUILDTIME_MCOUNT_SORT that is set when
      BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
      if sorting should take place at boot up.

      Add a test which allows us to test parsing an event alias with hyphens.
      
      Since these events typically do not exist on most host systems, add the
      alias to the fake pmu.
      
      Function perf_pmu__test_parse_init() has terms added to match known test
      aliases.

      perf parse-events: Support event alias in form foo-bar-baz · 864bc8c9
      John Garry authored
      Event aliasing for events whose name in the form foo-bar-baz is not
      supported, while foo-bar, foo_bar_baz, and other combinations are, i.e.
      two hyphens are not supported.
      
      The HiSilicon D06 platform has events in such form:
      
        $ ./perf list sdir-home-migrate
      
        List of pre-defined events (to be used in -e):

        event syntax error: 'sdir-home-migrate'
                                \___ parser error
        Run 'perf list' for a list of valid events
      
         Usage: perf stat [<options>] [<command>]
      
         -e, --event <event>event selector. use 'perf list' to list available events
      
      To support, add an extra PMU event symbol type for "baz", and add a new
      rule in the bison file.

      perf evsel: Override attr->sample_period for non-libpfm4 events · 3606c0e1
      German Gomez authored
      A previous patch preventing "attr->sample_period" values from being
      overridden in pfm events changed a related behaviour in arm-spe.
      
      Before said patch:
      
        perf record -c 10000 -e arm_spe_0// -- sleep 1
      
      Would yield an SPE event with period=10000. After the patch, the period
      in "-c 10000" was being ignored because the arm-spe code initializes
      sample_period to a non-zero value.
      
      This patch restores the previous behaviour for non-libpfm4 events.

      perf script: Fix printing 'phys_addr' failure issue · 9edcde68
      Yao Jin authored
      Perf script was failed to print the phys_addr for SPE profiling.
      One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR
      attribute set, perf script then exits with error.
      
      Now referring to 'addr', use evsel__do_check_stype() to check the type.
      
      Before:
      
        # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
      		store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
        # perf script -F pid,tid,addr,phys_addr
        Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field.
      
      After:
      
        # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
      		store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
        # perf script -F pid,tid,addr,phys_addr
        4064384/4064384 ffff802f921be0d0      2f921be0d0
        4064384/4064384 ffff802f921be0d0      2f921be0d0

      certs: Fix build error when CONFIG_MODULE_SIG_KEY is empty · e6340b65
      Masahiro Yamada authored
      Since b8c96a6b ("certs: simplify $(srctree)/ handling and remove
      config_filename macro"), when CONFIG_MODULE_SIG_KEY is empty,
      signing_key.x509 fails to build:
      
          CERT    certs/signing_key.x509
        Usage: extract-cert <source> <dest>
        make[1]: *** [certs/Makefile:78: certs/signing_key.x509] Error 2
        make: *** [Makefile:1831: certs] Error 2
      
      Pass "" to the first argument of extract-cert to fix the build error.

        certs/Makefile:77: *** target pattern contains no '%'.  Stop.
      
      Due to the typo, $(X509_DEP) contains a colon.
      
      Fix it.

      usr/include/Makefile: add linux/nfc.h to the compile-test coverage · 10756dc5
      Dmitry V. Levin authored
      As linux/nfc.h userspace compilation was finally fixed by commits
      79b69a83 ("nfc: uapi: use kernel size_t to fix user-space builds")
      and 7175f02c ("uapi: fix linux/nfc.h userspace compilation errors"),
      there is no need to keep the compile-test exception for it in
      usr/include/Makefile.
