      s390/irq: rework irq subclass handling · 82003c3e
      Heiko Carstens 提交于
      Let's not add a function for every external interrupt subclass for
      which we need reference counting. Just have two register/unregister
      functions which have a subclass parameter:
      
      void irq_subclass_register(enum irq_subclass subclass);
      void irq_subclass_unregister(enum irq_subclass subclass);

      s390/dumpstack: convert print_symbol to %pSR · 8237ac3c
      Heiko Carstens 提交于
      This is the same as what other architectures did.
      The change has also the advantage that there won't be any interleaving
      messages between printk() and print_symbol().

      s390/bpf,jit: fix address randomization · 4784955a
      Heiko Carstens 提交于
      Add misssing braces to hole calculation. This resulted in an addition
      instead of an substraction. Which in turn means that the jit compiler
      could try to write out of bounds of the allocated piece of memory.
      
      This bug was introduced with aa2d2c73 "s390/bpf,jit: address randomize
      and write protect jit code".
      
      Fixes this one:

      Pull cgroup updates from Tejun Heo:
       "A lot of activities on the cgroup front.  Most changes aren't visible
        to userland at all at this point and are laying foundation for the
        planned unified hierarchy.
      
         - The biggest change is decoupling the lifetime management of css
           (cgroup_subsys_state) from that of cgroup's.  Because controllers
           (cpu, memory, block and so on) will need to be dynamically enabled
           and disabled, css which is the association point between a cgroup
           and a controller may come and go dynamically across the lifetime of
           a cgroup.  Till now, css's were created when the associated cgroup
           was created and stayed till the cgroup got destroyed.
      
           Assumptions around this tight coupling permeated through cgroup
           core and controllers.  These assumptions are gradually removed,
           which consists bulk of patches, and css destruction path is
           completely decoupled from cgroup destruction path.  Note that
           decoupling of creation path is relatively easy on top of these
           changes and the patchset is pending for the next window.
      
         - cgroup has its own event mechanism cgroup.event_control, which is
           only used by memcg.  It is overly complex trying to achieve high
           flexibility whose benefits seem dubious at best.  Going forward,
           new events will simply generate file modified event and the
           existing mechanism is being made specific to memcg.  This pull
           request contains prepatory patches for such change.

       4) ACPICA update to version 20130725 includig fixes, cleanups, support
          for more than 256 GPEs per GPE block and a change to make the ACPI
          PM Timer optional (we've seen systems without the PM Timer in the
          field already).  One of the fixes, related to the DeRefOf operator,
          is necessary to prevent some Windows 8 oriented AML from causing

      11) Removal of Device Tree parsing for CPU device nodes from multiple
          cpufreq drivers that required some changes related to
          of_get_cpu_node() to be made in a few architectures and in the
          driver core.  From Sudeep KarkadaNagesha.

       "The first patch is to address a long standing issue where INQUIRY
        vendor + model response data was not correctly padded with ASCII
        spaces, causing MSFT and Falconstor multipath stacks to not function

        The second -> forth patches are additional iscsi-target regression
        fixes for the post >= v3.10 iser-target changes.  The second and third
        are failure cases that have appeared during further testing, and the
        forth is only reproducible with malformed NOP packets.
      
        The fifth patch is a v3.11 specific regression caused by a recent
        optimization that showed up during WRITE I/O failure testing.

      ipc/msg.c: Fix lost wakeup in msgsnd(). · bebcb928
      Manfred Spraul 提交于
      The check if the queue is full and adding current to the wait queue of
      pending msgsnd() operations (ss_add()) must be atomic.
      
      Otherwise:
       - the thread that performs msgsnd() finds a full queue and decides to
         sleep.
       - the thread that performs msgrcv() first reads all messages from the
         queue and then sleeps, because the queue is empty.
       - the msgrcv() calls do not perform any wakeups, because the msgsnd()
         task has not yet called ss_add().
       - then the msgsnd()-thread first calls ss_add() and then sleeps.
      
      Net result: msgsnd() and msgrcv() both sleep forever.
      
      Observed with msgctl08 from ltp with a preemptible kernel.
      
      Fix: Call ipc_lock_object() before performing the check.
      
      The patch also moves security_msg_queue_msgsnd() under ipc_lock_object:
       - msgctl(IPC_SET) explicitely mentions that it tries to expunge any
         pending operations that are not allowed anymore with the new
         permissions.  If security_msg_queue_msgsnd() is called without locks,
         then there might be races.
       - it makes the patch much simpler.

      Linus Torvalds 提交于
      Pull regulator updates from Mark Brown:
       "Not much exciting going on with the regulator API this time around,
        lots of driver fixes and enhancements - the main thing is the addition
        of a new API to help make the stubbing code do the right thing for
        missing regulator mappings.
      
        Highlights:
      
         - A new regulator_get_optional() API call for regulators that can be
           absent in normal operation.  This currently does nothing but will
           be used to improve the stubbing code for unspecified regulators,
           helping avoid some of the issues we've seen with adding new
           regulator support.
         - Helpers for devices with multiple linear ranges of voltages in the
           same regulator.
         - Moved the helpers into a separate file since core.c is getting
           rather large.
         - New drivers for Dialog DA9210 and DA9063, Freescale pfuze100 and
           Marvell 88pm800"
