      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.

      Use the correct the function name in the documentation for
      "pcs_parse_one_pinctrl_entry()".
      
      "smux_parse_one_pinctrl_entry()" appears to be an artifact from the
      development of a prior patch series ("simple pinmux driver") which
      transformed into pinctrl-single.

       "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"

      This reverts commit ba403242.
      
      After commit 26d8cde5 ("pinctrl: freescale: imx: add shared

      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:

      Pull RISC-V fixes from Palmer Dabbelt:
      
       - a workaround for a compiler surprise related to the "r" inline
         assembly that allows LLVM to boot.
      
       - a fix to avoid WX-only mappings, which the ISA does not allow. While
         this probably manifests in many ways, the bug was found in stress-ng.
      
       - a missing lock in set_direct_map_*(), which due to a recent lockdep
         change started asserting.

      afs: Fix hang on rmmod due to outstanding timer · 5481fc6e
      David Howells authored
      The fileserver probe timer, net->fs_probe_timer, isn't cancelled when
      the kafs module is being removed and so the count it holds on
      net->servers_outstanding doesn't get dropped..
      
      This causes rmmod to wait forever.  The hung process shows a stack like:
      
      	afs_purge_servers+0x1b5/0x23c [kafs]
      	afs_net_exit+0x44/0x6e [kafs]
      	ops_exit_list+0x72/0x93
      	unregister_pernet_operations+0x14c/0x1ba
      	unregister_pernet_subsys+0x1d/0x2a
      	afs_exit+0x29/0x6f [kafs]
      	__do_sys_delete_module.isra.0+0x1a2/0x24b
      	do_syscall_64+0x51/0x95
      	entry_SYSCALL_64_after_hwframe+0x44/0xa9
      
      Fix this by:
      
       (1) Attempting to cancel the probe timer and, if successful, drop the
           count that the timer was holding.
      
       (2) Make the timer function just drop the count and not schedule the
           prober if the afs portion of net namespace is being destroyed.
      
      Also, whilst we're at it, make the following changes:
      
       (3) Initialise net->servers_outstanding to 1 and decrement it before
           waiting on it so that it doesn't generate wake up events by being
           decremented to 0 until we're cleaning up.
      
       (4) Switch the atomic_dec() on ->servers_outstanding for ->fs_timer in
           afs_purge_servers() to use the helper function for that.
