      jfs: Fix inconsistency between memory allocation and ea_buf->max_size · 92d34134
      Shankara Pailoor authored
      The code is assuming the buffer is max_size length, but we weren't
      allocating enough space for it.

       - Avoid IPIs during CPU hotplug to read the MCx_MISC block address from
         a remote CPU. That's fragile and pointless because the block
         addresses are the same on all CPUs. So they can be read once and
         local.

      Pull irq updates from Thomas Gleixner:
      
       - Consolidation of softirq pending:
      
         The softirq mask and its accessors/mutators have many implementations
         scattered around many architectures. Most do the same things
         consisting in a field in a per-cpu struct (often irq_cpustat_t)
         accessed through per-cpu ops. We can provide instead a generic
         efficient version that most of them can use. In fact s390 is the only
         exception because the field is stored in lowcore.
      
       - Support for level!?! triggered MSI (ARM)
      
         Over the past couple of years, we've seen some SoCs coming up with
         ways of signalling level interrupts using a new flavor of MSIs, where
         the MSI controller uses two distinct messages: one that raises a
         virtual line, and one that lowers it. The target MSI controller is in
         charge of maintaining the state of the line.
      
         This allows for a much simplified HW signal routing (no need to have
         hundreds of discrete lines to signal level interrupts if you already
         have a memory bus), but results in a departure from the current idea
         the kernel has of MSIs.

       - Lots of tidying up changes all across the map for Linux's formal
         memory/locking-model tooling, by Alan Stern, Akira Yokosawa, Andrea
         Parri, Paul E. McKenney and SeongJae Park.
      
         Notable changes beyond an overall update in the tooling itself is the
         tidying up of spin_is_locked() semantics, which spills over into the
         kernel proper as well.
      
       - qspinlock improvements: the locking algorithm now guarantees forward
         progress whereas the previous implementation in mainline could starve
         threads indefinitely in cmpxchg() loops. Also other related cleanups
         to the qspinlock code (Will Deacon)
      
       - misc smaller improvements, cleanups and fixes all across the locking
         subsystem

       "This set of changes close the known issues with setting si_code to an
        invalid value, and with not fully initializing struct siginfo. There
        remains work to do on nds32, arc, unicore32, powerpc, arm, arm64, ia64
        and x86 to get the code that generates siginfo into a simpler and more
        maintainable state. Most of that work involves refactoring the signal
        handling code and thus careful code review.
      
        Also not included is the work to shrink the in kernel version of
        struct siginfo. That depends on getting the number of places that
        directly manipulate struct siginfo under control, as it requires the
        introduction of struct kernel_siginfo for the in kernel things.
      
        Overall this set of changes looks like it is making good progress, and

        problem if an unprivileged fuse filesystem is mounted.
      
        The rest of the changes are things that are now safe to allow a root

           though it still splits the whole range to 16MiB chunks
      
         - on user demand, rmdir() is able to delete an empty subvolume,
           export the capability in sysfs
      
         - fix inode number types in tracepoints, other cleanups
      
         - send: improved speed when dealing with a large removed directory,

           directory with 2 million entries
      
         - pre-commit check of superblock to detect a mysterious in-memory
           corruption
      
         - log message updates
      
        Other changes:
      
         - orphan inode cleanup improved, does no keep long-standing
           reservations that could lead up to early ENOSPC in some cases
      
         - slight improvement of handling snapshotted NOCOW files by avoiding
           some unnecessary tree searches
      
         - avoid OOM when dealing with many unmergeable small extents at flush
           time
      
         - speedup conversion of free space tree representations from/to
           bitmap/tree
      
         - code refactoring, deletion, cleanups:
            + delayed refs
            + delayed iput
            + redundant argument removals
            + memory barrier cleanups

      swait: strengthen language to discourage use · c5e7a7ea
      Linus Torvalds authored
      We already earlier discouraged people from using this interface in
      commit 88796e7e ("sched/swait: Document it clearly that the swait
      facilities are special and shouldn't be used"), but I just got a pull
      request with a new broken user.
      
      So make the comment *really* clear.
      
      The swait interfaces are bad, and should not be used unless you have
      some *very* strong reasons that include tons of hard performance numbers
      on just why you want to use them, and you show that you actually
      understand that they aren't at all like the normal wait/wakeup
      interfaces.
      
      So far, every single user has been suspect.  The main user is KVM, which
      is completely pointless (there is only ever one waiter, which avoids the
      interface subtleties, but also means that having a queue instead of a
      pointer is counter-productive and certainly not an "optimization").
      
      So make the comments much stronger.
      
      Not that anybody likely reads them anyway, but there's always some
      slight hope that it will cause somebody to think twice.
      
      I'd like to remove this interface entirely, but there is the theoretical
      possibility that it's actually the right thing to use in some situation,
      most likely some deep RT use.

       "Quite a busy release for SPI, mainly as a result of Boris Brezillon's

         - Lots of spring cleaning for the s3c64xx driver.
      
         - Removal of the bcm53xx, the hardware is also supported by the mspi
