      mm: correct the comment when reclaimed pages exceed the scanned pages · d7143e31
      zhongjiang authored 
      Commit e1587a49 ("mm: vmpressure: fix sending wrong events on
underflow") declared that reclaimed pages exceed the scanned pages due
to the thp reclaim.

That is incorrect because THP will be spilt to normal page and loop
again, which will result in the scanned pages increment.

      userfaultfd: shmem: handle coredumping in handle_userfault() · 64c2b203
      Andrea Arcangeli authored 
      Anon and hugetlbfs handle FOLL_DUMP set by get_dump_page() internally to
__get_user_pages().

shmem as opposed has no special FOLL_DUMP handling there so
handle_mm_fault() is invoked without mmap_sem and ends up calling
handle_userfault() that isn't expecting to be invoked without mmap_sem
held.

This makes handle_userfault() fail immediately if invoked through
shmem_vm_ops->fault during coredumping and solves the problem.

The side effect is a BUG_ON with no lock held triggered by the
coredumping process which exits.  Only 4.11 is affected, pre-4.11 anon
memory holes are skipped in __get_user_pages by checking FOLL_DUMP
explicitly against empty pagetables (mm/gup.c:no_page_table()).

It's zero cost as we already had a check for current->flags to prevent
futex to trigger userfaults during exit (PF_EXITING).

      mm: numa: avoid waiting on freed migrated pages · 3c226c63
      Mark Rutland authored 
      In do_huge_pmd_numa_page(), we attempt to handle a migrating thp pmd by
waiting until the pmd is unlocked before we return and retry.  However,
we can race with migrate_misplaced_transhuge_page():

    // do_huge_pmd_numa_page                // migrate_misplaced_transhuge_page()
    // Holds 0 refs on page                 // Holds 2 refs on page

    vmf->ptl = pmd_lock(vma->vm_mm, vmf->pmd);
    /* ... */
    if (pmd_trans_migrating(*vmf->pmd)) {
            page = pmd_page(*vmf->pmd);
            spin_unlock(vmf->ptl);
                                            ptl = pmd_lock(mm, pmd);
                                            if (page_count(page) != 2)) {
                                                    /* roll back */
                                            }
                                            /* ... */
                                            mlock_migrate_page(new_page, page);
                                            /* ... */
                                            spin_unlock(ptl);
                                            put_page(page);
                                            put_page(page); // page freed here
            wait_on_page_locked(page);
            goto out;
    }

This can result in the freed page having its waiters flag set
unexpectedly, which trips the PAGE_FLAGS_CHECK_AT_PREP checks in the
page alloc/free functions.  This has been observed on arm64 KVM guests.

We can avoid this by having do_huge_pmd_numa_page() take a reference on
the page before dropping the pmd lock, mirroring what we do in
__migration_entry_wait().

When we hit the race, migrate_misplaced_transhuge_page() will see the
reference and abort the migration, as it may do today in other cases.

      swap: cond_resched in swap_cgroup_prepare() · ef707629
      Yu Zhao authored 
      I saw need_resched() warnings when swapping on large swapfile (TBs)
because continuously allocating many pages in swap_cgroup_prepare() took
too long.

We already cond_resched when freeing page in swap_cgroup_swapoff().  Do
the same for the page allocation.

      mm/memory-failure.c: use compound_head() flags for huge pages · 7258ae5c
      James Morse authored 
      memory_failure() chooses a recovery action function based on the page
flags.  For huge pages it uses the tail page flags which don't have
anything interesting set, resulting in:

> Memory failure: 0x9be3b4: Unknown page state
> Memory failure: 0x9be3b4: recovery action for unknown page: Failed

Instead, save a copy of the head page's flags if this is a huge page,
this means if there are no relevant flags for this tail page, we use the
head pages flags instead.  This results in the me_huge_page() recovery
action being called:

> Memory failure: 0x9b7969: recovery action for huge page: Delayed

For hugepages that have not yet been allocated, this allows the hugepage
to be dequeued.

      Merge tag 'perf-urgent-for-mingo-4.12-20170616' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

- Fix probing of precise_ip level for default cycles event, that
  got broken recently on x86_64 when its arch code started
  considering invalid requesting precise samples when not sampling
  (i.e. when attr.sample_period == 0).

  This also fixes another problem in s/390 where the precision
  probing with sample_period == 0 returned precise_ip > 0, that
  then, when setting up the real cycles event (not probing) would
  return EOPNOTSUPP for precise_ip > 0 (as determined previously
  by probing) and sample_period > 0.

  These problems resulted in attr_precise not being set to the
  highest precision available on x86.64 when no event was specified,
  i.e. the canonical:

	perf record ./workload

  would end up using attr.precise_ip = 0. As a workaround this would
  need to be done:

	perf record -e cycles:P ./workload

  And on s/390 it would plain not work, requiring using:

        perf record -e cycles ./workload

  as a workaround.  (Arnaldo Carvalho de Melo)

- Fix perf build with ARCH=x86_64, when ARCH should be transformed
  into ARCH=x86, just like with the main kernel Makefile and
  tools/objtool's, i.e. use SRCARCH. (Jiada Wang)

- Avoid accessing uninitialized data structures when unwinding with
  elfutils's libdw, making it more closely mimic libunwind's unwinder.

      perf unwind: Report module before querying isactivation in dwfl unwind · 9126cbba
      Milian Wolff authored 
      The PC returned by dwfl_frame_pc() may map into a not-yet-reported
module. We have to report it before we continue unwinding. But when we
query for the isactivation flag in dwfl_frame_pc, libdw will actually do
one more unwinding step internally which can then break and lead to
missed frames or broken stacks.

With libunwind we get e.g.:

      objtool: Add fortify_panic as __noreturn function · 92b0a141
      Kees Cook authored 
      CONFIG_FORTIFY_SOURCE=y implements fortify_panic() as a __noreturn function,
so objtool needs to know about it too.

      Pull rdma fixes from Doug Ledford:

 "I had thought at the time of the last pull request that there wouldn't
  be much more to go, but several things just kept trickling in over the
  last week.

  Instead of just the six patches to bnxt_re that I had anticipated,
  there are another five IPoIB patches, two qedr patches, and a few
  other miscellaneous patches.

  The bnxt_re patches are more lines of diff than I like to submit this
  late in the game. That's mostly because of the first two patches in
  the series of six. I almost dropped them just because of the lines of
  churn, but on a close review, a lot of the churn came from removing
  duplicated code sections and consolidating them into callable
  routines. I felt like this made the number of lines of change more
  acceptable, and they address problems, so I left them. The remainder
  of the patches are all small, well contained, and well understood.

  These have passed 0day testing, but have not been submitted to
  linux-next (but a local merge test with your current master was
  without any conflicts).

  Summary:

   - A fix for fix eea40b8f ("infiniband: call ipv6 route lookup via
     the stub interface")

   - Six patches against bnxt_re...the first two are considerably larger
     than I would like, but as they address real issues I went ahead and
     submitted them (it also helped that a good deal of the churn was
     removing code repeated in multiple places and consolidating it to
     one common function)

   - Two fixes against qedr that just came in

   - One fix against rxe that took a few revisions to get right plus
     time to get the proper reviews

   - Five late breaking IPoIB fixes

   - One late cxgb4 fix"
