      drm/i915/params: switch to device specific parameters · 8a25c4be
      Jani Nikula authored
      Start using device specific parameters instead of module parameters for
      most things. The module parameters become the immutable initial values
      for i915 parameters. The device specific parameters in i915->params
      start life as a copy of i915_modparams. Any later changes are only
      reflected in the debugfs.
      
      The stragglers are:
      
      * i915.force_probe and i915.modeset. Needed before dev_priv is
        available. This is fine because the parameters are read-only and never
        modified.
      
      * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and
        I915_STATE_WARN_ON would result in massive and ugly churn. This is
        handled by not exposing the parameter via debugfs, and leaving the
        parameter writable in sysfs. This may be fixed up in follow-up work.
      
      * i915.inject_probe_failure. Only makes sense in terms of the module,
        not the device. This is handled by not exposing the parameter via
        debugfs.

      samples: watch_queue: build sample program for target architecture · 214377e9
      Masahiro Yamada authored
      This userspace program includes UAPI headers exported to usr/include/.
      'make headers' always works for the target architecture (i.e. the same
      architecture as the kernel), so the sample program should be built for
      the target as well. Kbuild now supports 'userprogs' for that.
      
      I also guarded the CONFIG option by 'depends on CC_CAN_LINK' because
      $(CC) may not provide libc.

      Revert "Makefile: install modules.builtin even if CONFIG_MODULES=n" · 2c6d9636
      Masahiro Yamada authored
      This reverts commit e0b250b5,
      which broke build systems that need to install files to a certain
      path, but do not set INSTALL_MOD_PATH when invoking 'make install'.
      
        $ make INSTALL_PATH=/tmp/destdir install
        mkdir: cannot create directory ‘/lib/modules/5.8.0-rc1+/’: Permission denied
        Makefile:1342: recipe for target '_builtin_inst_' failed
        make: *** [_builtin_inst_] Error 1
      
      While modules.builtin is useful also for CONFIG_MODULES=n, this change
      in the behavior is quite unexpected. Maybe "make modules_install"
      can install modules.builtin irrespective of CONFIG_MODULES as Jonas
      originally suggested.
      
      Anyway, that commit should be reverted ASAP.

      Pull libnvdimm updates from Dan Williams:
       "A feature (papr_scm health retrieval) and a fix (sysfs attribute
        visibility) for v5.8.
      
        Vaibhav explains in the merge commit below why missing v5.8 would be
        painful and I agreed to try a -rc2 pull because only cosmetics kept
        this out of -rc1 and his initial versions were posted in more than
        enough time for v5.8 consideration:
      
         'These patches are tied to specific features that were committed to
          customers in upcoming distros releases (RHEL and SLES) whose
          time-lines are tied to 5.8 kernel release.
      
          Being able to track the health of an nvdimm is critical for our
          customers that are running workloads leveraging papr-scm nvdimms.
          Missing the 5.8 kernel would mean missing the distro timelines and
          shifting forward the availability of this feature in distro kernels
          by at least 6 months'
      
        Summary:
      
         - Fix the visibility of the region 'align' attribute.
      
           The new unit tests for region alignment handling caught a corner
           case where the alignment cannot be specified if the region is
           converted from static to dynamic provisioning at runtime.
      
         - Add support for device health retrieval for the persistent memory
           supported by the papr_scm driver.
      
           This includes both the standard sysfs "health flags" that the nfit
           persistent memory driver publishes and a mechanism for the ndctl
           tool to retrieve a health-command payload"

      The patch adds missing qpic data pins to qpic pingroup. These pins are
      necessary for the qpic nand to work.

      Revert "pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource leak in case of error in 'imx_pinctrl_probe()'"
      
      This reverts commit ba403242.
      
      After commit 26d8cde5 ("pinctrl: freescale: imx: add shared
      input select reg support"). i.MX7D has two iomux controllers
      iomuxc and iomuxc-lpsr which share select_input register for
      daisy chain settings.
      If use 'devm_of_iomap()', when probe the iomuxc-lpsr, will call
      devm_request_mem_region() for the region <0x30330000-0x3033ffff>
      for the first time. Then, next time when probe the iomuxc, API
      devm_platform_ioremap_resource() will also use the API
      devm_request_mem_region() for the share region <0x30330000-0x3033ffff>
      again, then cause issue, log like below:
      
      [    0.179561] imx7d-pinctrl 302c0000.iomuxc-lpsr: initialized IMX pinctrl driver
      [    0.191742] imx7d-pinctrl 30330000.pinctrl: can't request region for resource [mem 0x30330000-0x3033ffff]
      [    0.191842] imx7d-pinctrl: probe of 30330000.pinctrl failed with error -16
      
      Fixes: ba403242 ("pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource leak in case of error in 'imx_pinctrl_probe()'")
