      selftests/powerpc: Purge extra count_pmc() calls of ebb selftests · 3337bf41
      Desnes A. Nunes do Rosario authored
      An extra count on ebb_state.stats.pmc_count[PMC_INDEX(pmc)] is being per-
      formed when count_pmc() is used to reset PMCs on a few selftests. This
      extra pmc_count can occasionally invalidate results, such as the ones from
      cycles_test shown hereafter. The ebb_check_count() failed with an above
      the upper limit error due to the extra value on ebb_state.stats.pmc_count.
      
      Furthermore, this extra count is also indicated by extra PMC1 trace_log on
      the output of the cycle test (as well as on pmc56_overflow_test):

      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

        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

          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

           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

      Pull s390 fixes from Vasily Gorbik:
      
       - a few ptrace fixes mostly for strace and seccomp_bpf kernel tests
         findings
      
       - cleanup unused pm callbacks in virtio ccw
      
       - replace kmalloc + memset with kzalloc in crypto
      
       - use $(LD) for vDSO linkage to make clang happy
      
       - fix vDSO clock_getres() to preserve the same behaviour as
         posix_get_hrtimer_res()
      
       - fix workqueue cpumask warning when NUMA=n and nr_node_ids=2
      
       - reduce SLSB writes during input processing, improve warnings and
         cleanup qdio_data usage in qdio
      
       - a few fixes to use scnprintf() instead of snprintf()
