      Pull rdma fixes from Doug Ledford:
       "This is our first pull request of the rc cycle. It's not that it's
        been overly quiet, we were just waiting on a few things before sending
        this off.
      
        For instance, the 6 patch series from Intel for the hfi1 driver had
        actually been pulled in on Tuesday for a Wednesday pull request, only
        to have Jason notice something I missed, so we held off for some
        testing, and then on Thursday had to respin the series because the
        very first patch needed a minor fix (unnecessary cast is all).
      
        There is a sizable hns patch series in here, as well as a reasonably
        largish hfi1 patch series, then all of the lines of uapi updates are
        just the change to the new official Linux-OpenIB SPDX tag (a bunch of
        our files had what amounts to a BSD-2-Clause + MIT Warranty statement
        as their license as a result of the initial code submission years ago,
        and the SPDX folks decided it was unique enough to warrant a unique
        tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4
        and core/cache/cma updates to round out the bunch.
      
        None of it was overly large by itself, but in the 2 1/2 weeks we've
        been collecting patches, it has added up :-/.
      
        As best I can tell, it's been through 0day (I got a notice about my
        last for-next push, but not for my for-rc push, but Jason seems to
        think that failure messages are prioritized and success messages not
        so much). It's also been through linux-next. And yes, we did notice in
        the context portion of the CMA query gid fix patch that there is a
        dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage
        and remove it anywhere we can.
      
        Summary:
      
         - Various build fixes (USER_ACCESS=m and ADDR_TRANS turned off)
      
         - SPDX license tag cleanups (new tag Linux-OpenIB)

      Masahiro Yamada authored
      Since commit d677a4d6 ("Makefile: support flag

      plugin under some circumstances.
      
        CONFIG_KCOV=y
        CONFIG_KCOV_ENABLE_COMPARISONS=y
        Your compiler does not support -fsanitize-coverage=trace-pc
        Your compiler does not support -fsanitize-coverage=trace-cmp
      
      Under this condition, $(CFLAGS_KCOV) is not empty but contains a
      space, so the following ifeq-conditional is false.
      
          ifeq ($(CFLAGS_KCOV),)
      
      Then, scripts/Makefile.gcc-plugins misses to add sancov_plugin.so to
      gcc-plugin-y while the SANCOV plugin is necessary as an alternative
      means.

      Right now it's possible to set dell laptop to compile in but this
      causes dell-smbios to compile in which breaks if dcdbas is a module.
      
      Dell laptop shouldn't select dell-smbios anymore, but depend on it.

      platform/x86: asus-wireless: Fix NULL pointer dereference · 9f0a93de
      João Paulo Rechi Vita authored
      When the module is removed the led workqueue is destroyed in the remove
      callback, before the led device is unregistered from the led subsystem.
      
      This leads to a NULL pointer derefence when the led device is
      unregistered automatically later as part of the module removal cleanup.
      Bellow is the backtrace showing the problem.

      let's keep Samsung on their names, using mchehab+samsung@kernel.org,
      in order to keep pointing to my employer, with sponsors the work.
      
      For the files written before I join Samsung (on July, 4 2013),
      let's just use mchehab@kernel.org.
      
      For bug reports, we can simply point to just kernel.org, as
      this will reach my mchehab+samsung inbox anyway.

      Jiri Slaby authored
      Commit 7ed1c190 (tools: fix cross-compile var clobbering) removed
      setting of LD to $(CROSS_COMPILE)gcc. This broke build of acpica
      (acpidump) in power/acpi:
       ld: unrecognized option '-D_LINUX'
      
      The tools pass CFLAGS to the linker (incl. -D_LINUX), so revert this
      particular change and let LD be $(CC) again. Note that the old behaviour
      was a bit different, it used $(CROSS_COMPILE)gcc which was eliminated by
      the commit 7ed1c190. We use $(CC) for that reason.
