      dma-debug: fix debug_dma_assert_idle(), use rcu_read_lock() · a85ffd59
      Hugh Dickins authored
      Since commit 2a9127fc ("mm: rewrite wait_on_page_bit_common()
      logic") improved unlock_page(), it has become more noticeable how
      cow_user_page() in a kernel with CONFIG_DMA_API_DEBUG=y can create and
      suffer from heavy contention on DMA debug's radix_lock in
      debug_dma_assert_idle().
      
      It is only doing a lookup: use rcu_read_lock() and rcu_read_unlock()
      instead; though that does require the static ents[] to be moved
      onstack...
      
      ...but, hold on, isn't that radix_tree_gang_lookup() and loop doing
      quite the wrong thing: searching CACHELINES_PER_PAGE entries for an
      exact match with the first cacheline of the page in question?
      radix_tree_gang_lookup() is the right tool for the job, but we need
      nothing more than to check the first entry it can find, reporting if
      that falls anywhere within the page.
      
      (Is RCU safe here? As safe as using the spinlock was. The entries are
      never freed, so don't need to be freed by RCU. They may be reused, and
      there is a faint chance of a race, with an offending entry reused while
      printing its error info; but the spinlock did not prevent that either,
      and I agree that it's not worth worrying about. ]
      
      [ Side noe: this patch is a clear improvement to the status quo, but the
        next patch will be removing this debug function entirely.
      
        But just in case we decide we want to resurrect the debugging code
        some day, I'm first applying this improvement patch so that it doesn't
        get lost    - Linus ]

       "A set of timekeeping/VDSO updates:
      
         - Preparatory work to allow S390 to switch over to the generic VDSO
           implementation.
      
           S390 requires that the VDSO data pointer is handed in to the
           counter read function when time namespace support is enabled.
           Adding the pointer is a NOOP for all other architectures because
           the compiler is supposed to optimize that out when it is unused in
           the architecture specific inline. The change also solved a similar
           problem for MIPS which fortunately has time namespaces not yet
           enabled.
      
           S390 needs to update clock related VDSO data independent of the
           timekeeping updates. This was solved so far with yet another
           sequence counter in the S390 implementation. A better solution is
           to utilize the already existing VDSO sequence count for this. The
           core code now exposes helper functions which allow to serialize
           against the timekeeper code and against concurrent readers.
      
           S390 needs extra data for their clock readout function. The initial
           common VDSO data structure did not provide a way to add that. It
           now has an embedded architecture specific struct embedded which
           defaults to an empty struct.
      
           Doing this now avoids tree dependencies and conflicts post rc1 and
           allows all other architectures which work on generic VDSO support
           to work from a common upstream base.
      
         - A trivial comment fix"

      Pull more timer updates from Thomas Gleixner:
       "A set of posix CPU timer changes which allows to defer the heavy work
        of posix CPU timers into task work context. The tick interrupt is
        reduced to a quick check which queues the work which is doing the
        heavy lifting before returning to user space or going back to guest
        mode. Moving this out is deferring the signal delivery slightly but
        posix CPU timers are inaccurate by nature as they depend on the tick
        so there is no real damage. The relevant test cases all passed.
      
        This lifts the last offender for RT out of the hard interrupt context
        tick handler, but it also has the general benefit that the actual
        heavy work is accounted to the task/process and not to the tick
        interrupt itself.
      
        Further optimizations are possible to break long sighand lock hold and
        interrupt disabled (on !RT kernels) times when a massive amount of
        posix CPU timers (which are unpriviledged) is armed for a
        task/process.
      
        This is currently only enabled for x86 because the architecture has to
        ensure that task work is handled in KVM before entering a guest, which
        was just established for x86 with the new common entry/exit code which
        got merged post 5.8 and is not the case for other KVM architectures"

      This can happen if ptrace() or sigreturn() pokes an LDT selector into FS
      or GS for a task with no LDT and something tries to read the base before
      a return to usermode notices the bad selector and fixes it.
      
      The fix is to make sure ldt pointer is not NULL.

      kconfig: qconf: do not limit the pop-up menu to the first row · fa8de0a3
      Masahiro Yamada authored
      If you right-click the first row in the option tree, the pop-up menu
      shows up, but if you right-click the second row or below, the event
      is ignored due to the following check:
      
        if (e->y() <= header()->geometry().bottom()) {
      
      Perhaps, the intention was to show the pop-menu only when the tree
      header was right-clicked, but this handler is not called in that case.
      
      Since the origin of e->y() starts from the bottom of the header,
      this check is odd.
      
      Going forward, you can right-click anywhere in the tree to get the
      pop-up menu.

      All the call-sites of this function pass 'this' to the first argument.
      
      So, 'parent' is always the 'this' pointer.

      This function allocates 'item' before using it, so the argument 'item'
