      Revert "parport: daisy: use new parport device model" · a3ac7917
      Linus Torvalds authored
      This reverts commit 1aec4211.
      
      Steven Rostedt reports that it causes a hang at bootup and bisected it
      to this commit.
      
      The troigger is apparently a module alias for "parport_lowlevel" that
      points to "parport_pc", which causes a hang with
      
          modprobe -q -- parport_lowlevel
      
      blocking forever with a backtrace like this:
      
          wait_for_completion_killable+0x1c/0x28
          call_usermodehelper_exec+0xa7/0x108
          __request_module+0x351/0x3d8
          get_lowlevel_driver+0x28/0x41 [parport]
          __parport_register_driver+0x39/0x1f4 [parport]
          daisy_drv_init+0x31/0x4f [parport]
          parport_bus_init+0x5d/0x7b [parport]
          parport_default_proc_register+0x26/0x1000 [parport]
          do_one_initcall+0xc2/0x1e0
          do_init_module+0x50/0x1d4
          load_module+0x1c2e/0x21b3
          sys_init_module+0xef/0x117
      
      Supid says:
       "Due to the new device model daisy driver will now try to find the
        parallel ports while trying to register its driver so that it can bind
        with them. Now, since daisy driver is loaded while parport bus is
        initialising the list of parport is still empty and it tries to load
        the lowlevel driver, which has an alias set to parport_pc, now causes
        a deadlock"
      
      But I don't think the daisy driver should be loaded by the parport
      initialization in the first place, so let's revert the whole change.
      
      If the daisy driver can just initialize separately on its own (like a
      driver should), instead of hooking into the parport init sequence
      directly, this issue probably would go away.

      Jonathan Hunter authored
      Enabling CQE support on Tegra186 Jetson TX2 has introduced a regression
      that is causing accesses to the file-system on the eMMC to fail. Errors
      such as the following have been observed ...
      
       mmc2: running CQE recovery
       mmc2: mmc_select_hs400 failed, error -110
       print_req_error: I/O error, dev mmcblk2, sector 8 flags 80700
       mmc2: cqhci: CQE failed to exit halt state
      
      For now disable CQE support for Tegra186 until this issue is resolved.

      ARM: dts: nomadik: Fix polarity of SPI CS · fa946356
      Linus Walleij authored
      The SPI DT bindings are for historical reasons a pitfall,
      the ability to flag a GPIO line as active high/low with
      the second cell flags was introduced later so the SPI
      subsystem will only accept the bool flag spi-cs-high
      to indicate that the line is active high.
      
      It worked by mistake, but the mistake was corrected
      in another commit.
      
      The comment in the DTS file was also misleading: this
      CS is indeed active high.

      locks: wake any locks blocked on request before deadlock check · 945ab8f6
      Jeff Layton authored
      Andreas reported that he was seeing the tdbtorture test fail in some
      cases with -EDEADLCK when it wasn't before. Some debugging showed that
      deadlock detection was sometimes discovering the caller's lock request
      itself in a dependency chain.
      
      While we remove the request from the blocked_lock_hash prior to
      reattempting to acquire it, any locks that are blocked on that request
      will still be present in the hash and will still have their fl_blocker
      pointer set to the current request.
      
      This causes posix_locks_deadlock to find a deadlock dependency chain
      when it shouldn't, as a lock request cannot block itself.
      
      We are going to end up waking all of those blocked locks anyway when we
      go to reinsert the request back into the blocked_lock_hash, so just do
      it prior to checking for deadlocks. This ensures that any lock blocked
      on the current request will no longer be part of any blocked request
      chain.

      bpf, libbpf: fix version info and add it to shared object · 1d382264
      Daniel Borkmann authored
      Even though libbpf's versioning script for the linker (libbpf.map)
      is pointing to 0.0.2, the BPF_EXTRAVERSION in the Makefile has
      not been updated along with it and is therefore still on 0.0.1.
      
      While fixing up, I also noticed that the generated shared object
      versioning information is missing, typical convention is to have
      a linker name (libbpf.so), soname (libbpf.so.0) and real name
      (libbpf.so.0.0.2) for library management. This is based upon the
      LIBBPF_VERSION as well.
      
      The build will then produce the following bpf libraries:
      
        # ll libbpf*
        libbpf.a
        libbpf.so -> libbpf.so.0.0.2
        libbpf.so.0 -> libbpf.so.0.0.2
        libbpf.so.0.0.2
      
        # readelf -d libbpf.so.0.0.2 | grep SONAME
        0x000000000000000e (SONAME)             Library soname: [libbpf.so.0]
      
      And install them accordingly:

       "Third more careful attempt for this set of fixes:
      
         - Prevent a 32bit math overflow in the cpufreq code
      
         - Fix a buffer overflow when scanning the cgroup2 cpu.max property
      
         - A set of fixes for the NOHZ scheduler logic to prevent waking up
           CPUs even if the capacity of the busy CPUs is sufficient along with
           other tweaks optimizing the behaviour for asymmetric systems

      Pull perf updates from Thomas Gleixner:
       "A larger set of perf updates.
      
        Not all of them are strictly fixes, but that's solely the tip
        maintainers fault as they let the timely -rc1 pull request fall
        through the cracks for various reasons including travel. So I'm
        sending this nevertheless because rebasing and distangling fixes and
        updates would be a mess and risky as well. As of tomorrow, a strict
        fixes separation is happening again. Sorry for the slip-up.
      
        Kernel:
      
         - Handle RECORD_MMAP vs. RECORD_MMAP2 correctly so different
           consumers of the mmap event get what they requested.
      
        Tools:
      
         - A larger set of updates to perf record/report/scripts vs. time
           stamp handling
      
         - More Python3 fixups
      
         - A pile of memory leak plumbing
      
         - perf BPF improvements and fixes
      
         - Finalize the perf.data directory storage"
      
      [ Note: the kernel part is strictly a fix, the updates are purely to
        tooling       - Linus ]
