      Linus Torvalds 提交于
      Pull GPIO tree bulk changes from Linus Walleij:
       "A big set this merge window, as we have much going on in this
        subsystem.  The changes to other subsystems (notably a slew of ARM
        machines as I am doing away with their custom APIs) have all been
        ACKed to the extent possible.
      
        Major changes this time:
      
         - Some core improvements and cleanups to the new GPIO descriptor API.
           This seems to be working now so we can start the exodus to this
           API, moving gradually away from the global GPIO numberspace.
      
         - Incremental improvements to the ACPI GPIO core, and move the few
           GPIO ACPI clients we have to the GPIO descriptor API right *now*
           before we go any further.  We actually managed to contain this
           *before* we started to litter the kernel with yet another hackish
           global numberspace for the ACPI GPIOs, which is a big win.
      
         - The RFkill GPIO driver and all platforms using it have been
           migrated to use the GPIO descriptors rather than fixed number
           assignments.  Tegra machine has been migrated as part of this.
      
         - New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x.  Those
           should be really good examples of how I expect a nice GPIO driver
           to look these days.
      
         - Do away with custom GPIO implementations on a major part of the ARM
           machines: ks8695, lpc32xx, mv78xx0.  Make a first step towards the
           same in the horribly convoluted Samsung S3C include forest.  We
           expect to continue to clean this up as we move forward.
      
         - Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and
           lynxpoint.
      
           This makes the GPIOlib core aware that a certain GPIO line is used
           for IRQs and can then enforce some semantics such as disallowing a
           GPIO line marked as in use for IRQ to be switched to output mode.
      
         - Drop all use of irq_set_chip_and_handler_name().  The name provided
           in these cases were just unhelpful tags like "mux" or "demux".
      
         - Extend the MCP23s08 driver to handle interrupts.
      
         - Minor incremental improvements for rcar, lynxpoint, em 74x164 and
           msm drivers.
      
         - Some non-urgent bug fixes here and there, duplicate #includes and
           that usual kind of cleanups"
      
      Fix up broken Kconfig file manually to make this all compile.

       "Here's the big driver core and sysfs patch set for 3.14-rc1.
      
        There's a lot of work here moving sysfs logic out into a "kernfs" to
        allow other subsystems to also have a virtual filesystem with the same
        attributes of sysfs (handle device disconnect, dynamic creation /
        removal as needed / unneeded, etc)
      
        This is primarily being done for the cgroups filesystem, but the goal
        is to also move debugfs to it when it is ready, solving all of the
        known issues in that filesystem as well.  The code isn't completed
        yet, but all should be stable now (there is a big section that was
        reverted due to problems found when testing)

         - 'perf record':
           - Rename --no-delay option to --no-buffering, better reflecting its
             purpose and freeing up '--delay' to take the place of
             '--initial-delay', so that 'record' and 'stat' are consistent
             (Arnaldo Carvalho de Melo)
           - Default the -t/--thread option to no inheritance (Adrian Hunter)
           - Make per-cpu mmaps the default (Adrian Hunter)
      
         - 'perf report':
           - Improve callchain processing performance (Frederic Weisbecker)
           - Retain bfd reference to lookup source line numbers, greatly
             optimizing, among other use cases, 'perf report -s srcline'
             (Adrian Hunter)
           - Improve callchain processing performance even more (Namhyung Kim)
           - Add a perf.data file header window in the 'perf report' TUI,
             associated with the 'i' hotkey, providing a counterpart to the
             --header option in the stdio UI (Namhyung Kim)
      
         - 'perf script':
           - Add an option in 'perf script' to print the source line number
             (Adrian Hunter)
           - Add --header/--header-only options to 'script' and 'report', the
             default is not tho show the header info, but as this has been the
             default for some time, leave a single line explaining how to
             obtain that information (Jiri Olsa)
           - Add options to show comm, fork, exit and mmap PERF_RECORD_ events
             (Namhyung Kim)
           - Print callchains and symbols if they exist (David Ahern)
      
         - 'perf timechart'
           - Add backtrace support to CPU info
           - Print pid along the name
           - Add support for CPU topology
           - Add new option --highlight'ing threads, be it by name or, if a
             numeric value is provided, that run more than given duration
             (Stanislav Fomichev)
      
         - 'perf top':
           - Make 'perf top -g' refer to callchains, for consistency with
             other tools (David Ahern)
      
         - 'perf trace':
           - Handle old kernels where the "raw_syscalls" tracepoints were
             called plain "syscalls" (David Ahern)
           - Remove thread summary coloring, by Pekka Enberg.
           - Honour -m option in 'trace', the tool was offering the option to
             set the mmap size, but wasn't using it when doing the actual mmap
             on the events file descriptors (Jiri Olsa)
      
         - generic:
           - Backport libtraceevent plugin support (trace-cmd repository, with
             plugins for jbd2, hrtimer, kmem, kvm, mac80211, sched_switch,
             function, xen, scsi, cfg80211 (Jiri Olsa)
           - Print session information only if --stdio is given (Namhyung Kim)
      
        Tooling side changes, developer visible (plumbing):
      
         - Improve 'perf probe' exit path, release resources (Masami
           Hiramatsu)
         - Improve libtraceevent plugins exit path, allowing the registering
           of an unregister handler to be called at exit time (Namhyung Kim)
         - Add an alias to the build test makefile (make -C tools/perf
           build-test) (Namhyung Kim)
         - Get rid of die() and friends (good riddance!) in libtraceevent
           (Namhyung Kim)
         - Fix cross build problems related to pkgconfig and CROSS_COMPILE not
           being propagated to the feature tests, leading to features being
           tested in the host and then being enabled on the target (Mark
           Rutland)
         - Improve forked workload error reporting by sending the errno in the
           signal data queueing integer field, using sigqueue and by doing the
           signal setup in the evlist methods, removing open coded equivalents
           in various tools (Arnaldo Carvalho de Melo)
         - Do more auto exit cleanup chores in the 'evlist' destructor, so
           that the tools don't have to all do that sequence (Arnaldo Carvalho
           de Melo)
         - Pack 'struct perf_session_env' and 'struct trace' (Arnaldo Carvalho
           de Melo)
         - Add test for building detached source tarballs (Arnaldo Carvalho de
           Melo)
         - Move some header files (tools/perf/ to tools/include/ to make them
           available to other tools/ dwelling codebases (Namhyung Kim)
         - Move logic to warn about kptr_restrict'ed kernels to separate
           function in 'report' (Arnaldo Carvalho de Melo)
         - Move hist browser selection code to separate function (Arnaldo
           Carvalho de Melo)
         - Move histogram entries collapsing to separate function (Arnaldo
           Carvalho de Melo)
         - Introduce evlist__for_each() & friends (Arnaldo Carvalho de Melo)
         - Automate setup of FEATURE_CHECK_(C|LD)FLAGS-all variables (Jiri
           Olsa)
         - Move arch setup into seprate Makefile (Jiri Olsa)
         - Make libtraceevent install target quieter (Jiri Olsa)
         - Make tests/make output more compact (Jiri Olsa)
         - Ignore generated files in feature-checks (Chunwei Chen)
         - Introduce pevent_filter_strerror() in libtraceevent, similar in
           purpose to libc's strerror() function (Namhyung Kim)
         - Use perf_data_file methods to write output file in 'record' and
           'inject' (Jiri Olsa)
         - Use pr_*() functions where applicable in 'report' (Namhyumg Kim)
         - Add 'machine' 'addr_location' struct to have full picture (machine,
           thread, map, symbol, addr) for a (partially) resolved address,
           reducing function signatures (Arnaldo Carvalho de Melo)
         - Reduce code duplication in the histogram entry creation/insertion
           (Arnaldo Carvalho de Melo)
         - Auto allocate annotation histogram data structures (Arnaldo
           Carvalho de Melo)
         - No need to test against NULL before calling free, also set freed
           memory in struct pointers to NULL, to help fixing use after free
           bugs (Arnaldo Carvalho de Melo)
         - Rename some struct DSO binary_type related members and methods, to
           clarify its purpose and need for differentiation (symtab_type, ie
           one is about the files .text, CFI, etc, i.e.  its binary contents,
           and the other is about where the symbol table came from (Arnaldo
           Carvalho de Melo)
         - Convert to new topic libraries, starting with an API one (sysfs,
           debugfs, etc), renaming liblk in the process (Borislav Petkov)
         - Get rid of some more panic() like error handling in libtraceevent.
           (Namhyung Kim)
         - Get rid of panic() like calls in libtraceevent (Namyung Kim)
         - Start carving out symbol parsing routines (perf, just moving
           routines to topic files in tools/lib/symbol/, tools that want to
           use it need to integrate it directly, ie no
           tools/lib/symbol/Makefile is provided (Arnaldo Carvalho de Melo)
         - Assorted refactoring patches, moving code around and adding utility
           evlist methods that will be used in the IPT patchset (Adrian
           Hunter)
         - Assorted mmap_pages handling fixes (Adrian Hunter)
         - Several man pages typo fixes (Dongsheng Yang)
         - Get rid of several die() calls in libtraceevent (Namhyung Kim)
         - Use basename() in a more robust way, to avoid problems related to
           different system library implementations for that function
           (Stephane Eranian)
         - Remove open coded management of short_name_allocated member (Adrian
           Hunter)
         - Several cleanups in the "dso" methods, constifying some parameters
           and renaming some fields to clarify its purpose (Arnaldo Carvalho
           de Melo)
         - Add per-feature check flags, fixing libunwind related build
           problems on some architectures (Jean Pihet)
         - Do not disable source line lookup just because of one failure.
           (Adrian Hunter)
         - Several 'perf kvm' man page corrections (Dongsheng Yang)
         - Correct the message in feature-libnuma checking, swowing the right
           devel package names for various distros (Dongsheng Yang)
         - Polish 'readn()' function and introduce its counterpart,
           'writen()' (Jiri Olsa)
         - Start moving timechart state from global variables to a 'perf_tool'
           derived 'timechart' struct (Arnaldo Carvalho de Melo)
