      platform/x86: Remove left-over BACKLIGHT_LCD_SUPPORT · 8d4b2daf
      Krzysztof Kozlowski authored
      The CONFIG_BACKLIGHT_LCD_SUPPORT was removed in commit 8c5dc8d9
      ("video: backlight: Remove useless BACKLIGHT_LCD_SUPPORT kernel
      symbol"). Options protected by CONFIG_BACKLIGHT_LCD_SUPPORT are now
      available directly.

      platform/x86: mlx-platform: Fix parent device in i2c-mux-reg device registration · fa882fc8
      Vadim Pasternak authored
      Fix the issue found while running kernel with the option
      CONFIG_DEBUG_TEST_DRIVER_REMOVE.
      Driver 'mlx-platform' registers 'i2c_mlxcpld' device and then registers
      few underlying 'i2c-mux-reg' devices:
      	priv->pdev_i2c = platform_device_register_simple("i2c_mlxcpld", nr,
      							 NULL, 0);
      	...
      	for (i = 0; i < ARRAY_SIZE(mlxplat_mux_data); i++) {
      		priv->pdev_mux[i] = platform_device_register_resndata(
      						&mlxplat_dev->dev,
      						"i2c-mux-reg", i, NULL,
      						0, &mlxplat_mux_data[i],
      						sizeof(mlxplat_mux_data[i]));
      
      But actual parent of "i2c-mux-reg" device is priv->pdev_i2c->dev and
      not mlxplat_dev->dev.
      Patch fixes parent device parameter in a call to
      platform_device_register_resndata() for "i2c-mux-reg".
      
      It solves the race during initialization flow while 'i2c_mlxcpld.1' is
      removing after probe, while 'i2c-mux-reg.0' is still in probing flow:
      'i2c_mlxcpld.1'	flow:	probe -> remove -> probe.
      'i2c-mux-reg.0'	flow:		  probe -> ...

      platform/x86: intel-vbtn: Report switch events when event wakes device · 89ae3a07
      Mathew King authored
      When a switch event, such as tablet mode/laptop mode or docked/undocked,
      wakes a device make sure that the value of the swich is reported.
      Without when a device is put in tablet mode from laptop mode when it is
      suspended or vice versa the device will wake up but mode will be
      incorrect.
      
      Tested by suspending a device in laptop mode and putting it in tablet
      mode, the device resumes and is in tablet mode. When suspending the
      device in tablet mode and putting it in laptop mode the device resumes
      and is in laptop mode.

      platform/x86: asus-wmi: Only Tell EC the OS will handle display hotkeys from asus_nb_wmi · 1dd93f87
      Hans de Goede authored
      Commit 78f3ac76 ("platform/x86: asus-wmi: Tell the EC the OS will
      handle the display off hotkey") causes the backlight to be permanently off
      on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
      1015BX, Asus EeePC 1025C).
      
      The asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL) call added
      by that commit is made conditional in this commit and only enabled in
      the quirk_entry structs in the asus-nb-wmi driver fixing the broken
      display / backlight on various EeePC laptop models.

      Adding the dependency seems like a more reasonable thing compared to
      ifdef-ing the bits, as if one has an XO-1.75 they almost certainly want
      a baterry and AC adapter support.

       "perf.data:
      
         - Streaming compression of perf ring buffer into
           PERF_RECORD_COMPRESSED user space records, resulting in ~3-5x
           perf.data file size reduction on variety of tested workloads what
           saves storage space on larger server systems where perf.data size
           can easily reach several tens or even hundreds of GiBs, especially
           when profiling with DWARF-based stacks and tracing of context
           switches.
      
        perf record:
      
         - Improve -user-regs/intr-regs suggestions to overcome errors
      
        perf annotate:
      
         - Remove hist__account_cycles() from callback, speeding up branch
           processing (perf record -b)

         - Add a 'percore' event qualifier, e.g.: -e
           cpu/event=0,umask=0x3,percore=1/, that sums up the event counts for
           both hardware threads in a core.
      
           We can already do this with --per-core, but it's often useful to do
           this together with other metrics that are collected per hardware
           thread.
      
           I.e. now its possible to do this per-event, and have it mixed with
           other events not aggregated by core.

         - Map Brahma-B53 CPUID to cortex-a53 events.
      
         - Add Cortex-A57 and Cortex-A72 events.
      
        csky:
      
         - Add DWARF register mappings for libdw, allowing --call-graph=dwarf
           to work on the C-SKY arch.
      
        x86:
      
         - Add support for recording and printing XMM registers, available,
           for instance, on Icelake.
      
         - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON
           support. UPI replaced the Intel QuickPath Interconnect (QPI) in
           Xeon Skylake-SP.

         - Fix instructions sampling rate.

       "This is some material that we picked up into our tree late. Most of it
        are smaller fixes and additions, some defconfig updates due to recent
        development, etc.
      
        Code-wise the largest portion is a series of PM updates for the at91
        platform, and those have been in linux-next a while through the at91
        tree before we picked them up"

       "One fix going back to stable, for a bug on 32-bit introduced when we
        added support for THREAD_INFO_IN_TASK.
      
        A fix for a typo in a recent rework of our hugetlb code that leads to
        crashes on 64-bit when using hugetlbfs with a 4K PAGE_SIZE.
      
        Two fixes for our recent rework of the address layout on 64-bit hash
        CPUs, both only triggered when userspace tries to access addresses
        outside the user or kernel address ranges.

      Pull RISC-V updates from Palmer Dabbelt:
       "This contains an assortment of RISC-V related patches that I'd like to
        target for the 5.2 merge window. Most of the patches are cleanups, but
        there are a handful of user-visible changes:
      
         - The nosmp and nr_cpus command-line arguments are now supported,
           which work like normal.
      
         - The SBI console no longer installs itself as a preferred console,
           we rely on standard mechanisms (/chosen, command-line, hueristics)
           instead.
      
         - sfence_remove_sfence_vma{,_asid} now pass their arguments along to
           the SBI call.
      
         - Modules now support BUG().
      
         - A missing sfence.vma during boot has been added. This bug only
           manifests during boot.
      
         - The arch/riscv support for SiFive's L2 cache controller has been
           merged, which should un-block the EDAC framework work.
      
        I've only tested this on QEMU again, as I didn't have time to get
        things running on the Unleashed. The latest master from this morning
        merges in cleanly and passes the tests as well"

      Masahiro Yamada authored
      'ifeq ... else ifneq ... endif' notation is supported by GNU Make 3.81
      or later, which is the requirement for building the kernel since
      commit 37d69ee3 ("docs: bump minimal GNU Make version to 3.81").
      
      Use it to improve the readability.
