      arm64: cpuidle: make arm_cpuidle_suspend() a bit more efficient · b5fda7ed
      Jisheng Zhang authored
      Currently, we check two pointers: cpu_ops and cpu_suspend on every idle
      state entry. These pointers check can be avoided:
      
      If cpu_ops has not been registered, arm_cpuidle_init() will return
      -EOPNOTSUPP, so arm_cpuidle_suspend() will never have chance to
      run. In other word, the cpu_ops check can be avoid.
      
      Similarly, the cpu_suspend check could be avoided in this hot path by
      moving it into arm_cpuidle_init().
      
      I measured the 4096 * time from arm_cpuidle_suspend entry point to the
      cpu_psci_cpu_suspend entry point. HW platform is Marvell BG4CT STB
      board.
      
      1. only one shell, no other process, hot-unplug secondary cpus, execute
      the following cmd
      
      while true
      do
      	sleep 0.2
      done
      
      before the patch: 1581220ns
      
      after the patch: 1579630ns
      
      reduced by 0.1%
      
      2. only one shell, no other process, hot-unplug secondary cpus, execute
      the following cmd
      
      while true
      do
      	md5sum /tmp/testfile
      	sleep 0.2
      done
      
      NOTE: the testfile size should be larger than L1+L2 cache size
      
      before the patch: 1961960ns
      after the patch: 1912500ns
      
      reduced by 2.5%
      
      So the more complex the system load, the bigger the improvement.

      Revert "ext4: allow readdir()'s of large empty directories to be interrupted" · 9f2394c9
      Linus Torvalds authored
      This reverts commit 1028b55b.
      
      It's broken: it makes ext4 return an error at an invalid point, causing
      the readdir wrappers to write the the position of the last successful
      directory entry into the position field, which means that the next
      readdir will now return that last successful entry _again_.
      
      You can only return fatal errors (that terminate the readdir directory
      walk) from within the filesystem readdir functions, the "normal" errors
      (that happen when the readdir buffer fills up, for example) happen in
      the iterorator where we know the position of the actual failing entry.
      
      I do have a very different patch that does the "signal_pending()"
      handling inside the iterator function where it is allowable, but while
      that one passes all the sanity checks, I screwed up something like four
      times while emailing it out, so I'm not going to commit it today.
      
      So my track record is not good enough, and the stars will have to align
      better before that one gets committed.  And it would be good to get some
      review too, of course, since celestial alignments are always an iffy
      debugging model.
      
      IOW, let's just revert the commit that caused the problem for now.

        In addition, due to that breakage, Mikulas Patocka noticed that
        handling exceptions from modules probably never worked on parisc.  It
        was just masked by the fact that exceptions from modules don't happen
        during normal use.

      Pull GPIO fixes from Linus Walleij:
       "Here is a set of four GPIO fixes.  The two fixes to the core are
        serious as they are regressing minor architectures.
      
        Core fixes:
      
         - Defer GPIO device setup until after gpiolib is initialized.
      
           It turns out that a few very tightly integrated GPIO platform
           drivers initialize so early (befor core_initcall()) so that the
           gpiolib isn't even initialized itself.  That limits what the
           library can do, and we cannot reference uninitialized fields until
           later.
      
           Defer some of the initialization until right after the gpiolib is
           initialized in these (rare) cases.
      
         - As a consequence: do not use devm_* resources when allocating the
           states in the initial set-up of the gpiochip.
      
        Driver fixes:
      
         - In ACPI retrieveal: ignore GpioInt when looking for output GPIOs.
      
         - Fix legacy builds on the PXA without a backing pin controller.
      
         - Use correct datatype on pca953x register writes"

      Make sure we avoid a division-by-zero OOPS in case clock-frequency is
      set too low in DT. Add missing '\n' while we are here.
