  1. mm/debug_vm_pgtable: Fix corrupted page flag

    In page table entry modifying tests, set_xxx_at() are used to populate
    the page table entries. On ARM64, PG_arch_1 is set to the target page
    flag if execution permission is given. The page flag is kept when the
    page is free'd to buddy's free area list. However, it will trigger page
    checking failure when it's pulled from the buddy's free area list, as
    the following warning messages indicate.
    
       BUG: Bad page state in process memhog  pfn:08000
       page:0000000015c0a628 refcount:0 mapcount:0 \

       page dumped because: PAGE_FLAGS_CHECK_AT_PREP flag(s) set
    
    This fixes the issue by clearing PG_arch_1 through flush_dcache_page()
    after set_xxx_at() is called.

       * Move hugetlb_basic_tests() so that the basic tests are treated
         as a bundle.
    
       * Drop parameters to {pgd, p4d}_basic_tests() as they're never
         used.

  12. mm/debug_vm_pgtable: Introduce struct pgtable_debug_args

    In debug_vm_pgtable(), there are many local variables introduced to
    track the needed information and they are passed to the functions for
    various test cases. It'd better to introduce a struct as place holder
    for these information. With it, what the functions for various test
    cases need is the struct, to simplify the code. It also makes code
    easier to be maintained.
    
    Besides, set_xxx_at() could access the data on the corresponding pages
    in the page table modifying tests. So the accessed pages in the tests
    should have been allocated from buddy. Otherwise, we're accessing pages
    that aren't owned by us. This causes issues like page flag corruption.
    
    This introduces "struct pgtable_debug_args". The struct is initialized
    and destroyed, but the information in the struct isn't used yet. They
    will be used in subsequent patches.

  7. Kbuild: lto: fix module versionings mismatch in GNU make 3.X

    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.

  8. kbuild: do not suppress Kconfig prompts for silent build

    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 174a1dc ("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.

    The commit 042da42 ("scripts/setlocalversion: simplify the short

    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.

  10. perf sched: Fix record failure when CONFIG_SCHEDSTATS is not set

    The tracepoints trace_sched_stat_{wait, sleep, iowait} are not exposed to user
    if CONFIG_SCHEDSTATS is not set, "perf sched record" records the three events.
    As a result, the command fails.
    
    Before:
    
      #perf sched record sleep 1
      event syntax error: 'sched:sched_stat_wait'
                           \___ unknown tracepoint
    
      Error:  File /sys/kernel/tracing/events/sched/sched_stat_wait not found.
      Hint:   Perhaps this kernel misses some CONFIG_ setting to enable this feature?.
    
      Run 'perf list' for a list of valid events
    
       Usage: perf record [<options>] [<command>]
          or: perf record [<options>] -- <command> [<options>]
    
          -e, --event <event>   event selector. use 'perf list' to list available events
    
    Solution:
      Check whether schedstat tracepoints are exposed. If no, these events are not recorded.
    
    After:
      # perf sched record sleep 1
      [ perf record: Woken up 1 times to write data ]
      [ perf record: Captured and wrote 0.163 MB perf.data (1091 samples) ]

  11. perf probe: Fix add event failure when running 32-bit perf in a 64-bi…

    …t kernel
    
    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().
    
    Before:
    
      # perf probe -a schedule
      schedule is out of .text, skip it.
        Error: Failed to add events.
    
    Solution:
      Change data type of "address" variable to u64 and change corresponding
    address printing and value assignment.
    
    After:
    
      # 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
    
      # perf probe -l
        probe:schedule       (on schedule@kernel/sched/core.c)
      # perf record -e probe:schedule -aR sleep 1

  12. perf data: Close all files in close_dir()

    When using 'perf report' in directory mode, the first file is not closed
    on exit, causing a memory leak.
    
    The problem is caused by the iterating variable never reaching 0.

  2. Revert "mm/slub: use stackdepot to save stack trace in objects"

    This reverts commit 7886914.
    
    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.

      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
