      Kbuild: lto: fix module versionings mismatch in GNU make 3.X · 1d11053d
      Lecopzer Chen authored
      When building modules(CONFIG_...=m), I found some of module versions
      are incorrect and set to 0.
      This can be found in build log for first clean build which shows
      WARNING: EXPORT symbol "XXXX" [drivers/XXX/XXX.ko] version generation failed,
      symbol will not be versioned.
      But in second build(incremental build), the WARNING disappeared and the
      module version becomes valid CRC and make someone who want to change
      modules without updating kernel image can't insert their modules.
      The problematic code is
      +	$(foreach n, $(filter-out FORCE,$^),				\
      +		$(if $(wildcard $(n).symversions),			\
      +			; cat $(n).symversions >> $@.symversions))
      For example:
        rm -f fs/notify/built-in.a.symversions    ; rm -f fs/notify/built-in.a; \
      llvm-ar cDPrST fs/notify/built-in.a fs/notify/fsnotify.o \
      fs/notify/notification.o fs/notify/group.o ...
      `foreach n` shows nothing to `cat` into $(n).symversions because
      `if $(wildcard $(n).symversions)` return nothing, but actually
      they do exist during this line was executed.
      -rw-r--r-- 1 root root 168580 Jun 13 19:10 fs/notify/fsnotify.o
      -rw-r--r-- 1 root root    111 Jun 13 19:10 fs/notify/fsnotify.o.symversions
      The reason is the $(n).symversions are generated at runtime, but
      Makefile wildcard function expends and checks the file exist or not
      during parsing the Makefile.
      Thus fix this by use `test` shell command to check the file
      existence in runtime.

      kbuild: do not suppress Kconfig prompts for silent build · d952cfaf
      Masahiro Yamada authored
      When a new CONFIG option is available, Kbuild shows a prompt to get
      the user input.
        $ make
        [ snip ]
        Core Scheduling for SMT (SCHED_CORE) [N/y/?] (NEW)
      This is the only interactive place in the build process.
      Commit 174a1dcc ("kbuild: sink stdout from cmd for silent build")
      suppressed Kconfig prompts as well because syncconfig is invoked by
      the 'cmd' macro. You cannot notice the fact that Kconfig is waiting
      for the user input.
      Use 'kecho' to show the equivalent short log without suppressing stdout
      from sub-make.

      scripts/setlocalversion: fix a bug when LOCALVERSION is empty · 5df99bec
      Mikulas Patocka authored
      The commit 042da426 ("scripts/setlocalversion: simplify the short
      version part") reduces indentation. Unfortunately, it also changes behavior
      in a subtle way - if the user has empty "LOCALVERSION" variable, the plus
      sign is appended to the kernel version. It wasn't appended before.
      This patch reverts to the old behavior - we append the plus sign only if
      the LOCALVERSION variable is not set.

      perf sched: Fix record failure when CONFIG_SCHEDSTATS is not set · b0f00855
      Yang Jihong authored
      The tracepoints trace_sched_stat_{wait, sleep, iowait} are not exposed to user

      perf probe: Fix add event failure when running 32-bit perf in a 64-bit kernel · 22a66551
      Yang Jihong authored
      The "address" member of "struct probe_trace_point" uses long data type.
      If kernel is 64-bit and perf program is 32-bit, size of "address"
      variable is 32 bits.
      As a result, upper 32 bits of address read from kernel are truncated, an
      error occurs during address comparison in kprobe_warn_out_range().
        # perf probe -a schedule
        schedule is out of .text, skip it.
          Error: Failed to add events.
        Change data type of "address" variable to u64 and change corresponding
      address printing and value assignment.
        # perf.new.new probe -a schedule
        Added new event:
          probe:schedule       (on schedule)
        You can now use it in all perf tools, such as:
                perf record -e probe:schedule -aR sleep 1

      Revert "mm/slub: use stackdepot to save stack trace in objects" · ae14c63a
      Linus Torvalds authored
      This reverts commit 78869146.
      It's not clear why, but it causes unexplained problems in entirely
      unrelated xfs code.  The most likely explanation is some slab
      corruption, possibly triggered due to CONFIG_SLUB_DEBUG_ON.  See [1].
      It ends up having a few other problems too, like build errors on
      arch/arc, and Geert reporting it using much more memory on m68k [3] (it
      probably does so elsewhere too, but it is probably just more noticeable
      on m68k).
      The architecture issues (both build and memory use) are likely just
      because this change effectively force-enabled STACKDEPOT (along with a
      very bad default value for the stackdepot hash size).  But together with
      the xfs issue, this all smells like "this commit was not ready" to me.

       "The bulk of the diffstat consists of changes to our uaccess routines
        so that they fall back to bytewise copying prior to reporting complete

        ARCH_DMA_MINALIGN back to 128 bytes thanks to Qualcomm's "Kryo" CPU,
        which ended up in the MSM8996 mobile SoC. Still, at least we're now
        aware of this design and one of the hardware designers confirmed the
