      usb: gadget: udc: core: Document the relation between usb_ep_queue() and completion callback · 5d1332a8
      Alan Stern authored
      Improve the kerneldoc for usb_ep_queue() to note explicitly that the
      request's completion routine will be called if and only if the return
      value is 0.  The corresponding fact about usb_submit_urb() for the
      host-side API has long been documented, and this has always been the
      intention for the gadget API.  But until now, documentation seems to
      have been lacking.

      Remove Exynos specific framebuffer structure and
      relevant functions.
      - it removes exynos_drm_fb structure which is a wrapper of
        drm_framebuffer and unnecessary two exynos specific callback
        functions, exynos_drm_destory() and exynos_drm_fb_create_handle()
        because we can reuse existing drm common callback ones instead.

       "A larger set of updates for perf.
      
        Kernel:
      
         - Handle the SBOX uncore monitoring correctly on Broadwell CPUs which
           do not have SBOX.
      
         - Store context switch out type in PERF_RECORD_SWITCH[_CPU_WIDE]. The
           percentage of preempting and non-preempting context switches help
           understanding the nature of workloads (CPU or IO bound) that are
           running on a machine. This adds the kernel facility and userspace
           changes needed to show this information in 'perf script' and 'perf
           report -D' (Alexey Budankov)
      
         - Remove a WARN_ON() in the trace/kprobes code which is pointless
           because the return error code is already telling the caller what's
           wrong.
      
         - Revert a fugly workaround for clang BPF targets.
      
         - Fix sample_max_stack maximum check and do not proceed when an error
           has been detect, return them to avoid misidentifying errors (Jiri
           Olsa)
      
         - Add SPDX idenitifiers and get rid of GPL boilderplate.
      
        Tools:
      
         - Synchronize kernel ABI headers, v4.17-rc1 (Ingo Molnar)
      
         - Support MAP_FIXED_NOREPLACE, noticed when updating the
           tools/include/ copies (Arnaldo Carvalho de Melo)
      
         - Add '\n' at the end of parse-options error messages (Ravi Bangoria)
      
         - Add s390 support for detailed/verbose PMU event description (Thomas
           Richter)
      
         - perf annotate fixes and improvements:
      
            * Allow showing offsets in more than just jump targets, use the
              new 'O' hotkey in the TUI, config ~/.perfconfig
              annotate.offset_level for it and for --stdio2 (Arnaldo Carvalho
              de Melo)
      
            * Use the resolved variable names from objdump disassembled lines
              to make them more compact, just like was already done for some
              instructions, like "mov", this eventually will be done more
              generally, but lets now add some more to the existing mechanism
              (Arnaldo Carvalho de Melo)
      
         - perf record fixes:
      
            * Change warning for missing topology sysfs entry to debug, as not
              all architectures have those files, s390 being one of those
              (Thomas Richter)
      
            * Remove old error messages about things that unlikely to be the
              root cause in modern systems (Andi Kleen)
      
         - perf sched fixes:
      
            * Fix -g/--call-graph documentation (Takuya Yamamoto)
      
         - perf stat:
      
            * Enable 1ms interval for printing event counters values in
              (Alexey Budankov)
      
         - perf test fixes:
      
            * Run dwarf unwind on arm32 (Kim Phillips)
      
            * Remove unused ptrace.h include from LLVM test, sidesteping older
              clang's lack of support for some asm constructs (Arnaldo
              Carvalho de Melo)
      
            * Fixup BPF test using epoll_pwait syscall function probe, to cope
              with the syscall routines renames performed in this development
              cycle (Arnaldo Carvalho de Melo)
      
         - perf version fixes:
      
            * Do not print info about HAVE_LIBAUDIT_SUPPORT in 'perf version
              --build-options' when HAVE_SYSCALL_TABLE_SUPPORT is true, as
              libaudit won't be used in that case, print info about
              syscall_table support instead (Jin Yao)
      
         - Build system fixes:
      
            * Use HAVE_..._SUPPORT used consistently (Jin Yao)
      
            * Restore READ_ONCE() C++ compatibility in tools/include (Mark
              Rutland)

      Pull libnvdimm fixes from Dan Williams:
       "A regression fix, new unit test infrastructure and a build fix:
      
         - Regression fix addressing support for the new NVDIMM label storage
           area access commands (_LSI, _LSR, and _LSW).
      
           The Intel specific version of these commands communicated the
           "Device Locked" status on the label-storage-information command.
      
           However, these new commands (standardized in ACPI 6.2) communicate
           the "Device Locked" status on the label-storage-read command, and
           the driver was missing the indication.
      
           Reading from locked persistent memory is similar to reading
           unmapped PCI memory space, returns all 1's.
      
         - Unit test infrastructure is added to regression test the "Device
           Locked" detection failure.
      
         - A build fix is included to allow the "of_pmem" driver to be built
           as a module and translate an Open Firmware described device to its
           local numa node"
