      [PATCH] s390: system call speedup part 1. · 42aef4b0
      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      The purpose of this is to speed up system calls on s390.  I managed to
      squeeze about 65 cycles from each system call.  This improved e.g.  getpid()
      from 232 to 157 cycles.  As a nice side-effect it simplified the uaccess
      functions considerably.

      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      s390 tape driver changes:
       - Prevent offline while device is in use.
       - Do not use bus_id string in debug feature messages.
       - Check for IS_ERR(irb) error conditions in interrupt handler.
       - Fix removing tape discipline modules.

      [PATCH] s390: network driver. · 0dc80d7c
      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      s390 network driver changes:
       - ctc/lcs/qeth: prevent a ccw-device to be grouped multiple times.
       - icuv: clear correct field in iucv_register_program if no userid is specified.
       - lcs: fix online/offline cycle again.
       - lcs: fix ungrouping of lcs group device. The channels of the lcs card
         should be offline afterwards.
       - lcs: don't do netif_stop_queue if no tx buffer is available, just
         return -EBUSY and drop the packets.

      [PATCH] s390: dasd driver. · 8fea2343
      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      dasd device driver changes:
       - After a state change interrupt restart all running i/o on queue
         and reset device timer.
       - Improve some debug messages.
       - Lower timeout of reserve/release/steal_lock to 2 seconds.
       - Fix BIODASDPSRD ioctl.
       - Replace ro_flag, use_diag_flag and disconnect_error_flag words by bits.
       - Use BLKPG_DEL_PARTITION ioctl instead of a call to delete_partition because
         delete_partition is not an exported function. Since dasd_destroy_partitions
         can't do blkdev_get because dasd_open would fail, keep the block device
         open as long as partitions exist. This in turn requires a different
         approach to the open vs. offline race.

      [PATCH] s390: core fixes. · d2ca1196
      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      s390 core changes:
       - Fix return type of some system call functions (long vs. int).
       - Fix prototypes for compat system call handlers.
       - Correct some bugs in the compat system call wrappers.
       - Fix broken pointer arithmetic which causes problems with
         gcc 3.4 and -march=z990
       - Remove unnecessary #ifndef & optimize inline assemblies in spinlock.h.
       - Improve handling of deferred condition code 1.
       - New default configuration.

      Andrew Morton authored
      From: badari <pbadari@us.ibm.com>
      
      I ran into an ipc hang while trying to shutdown a database.  The problem is
      due to missing sem_unlock() in find_undo().

      [PATCH] Fix cyclades async driver timeout miscalculation · fbd033be
      Marcelo Tosatti authored
      This fixes a problem where cy_wait_until_sent() miscalculates (calculate
      -1 on a unsigned long) the "char_time" parameter passed to
      schedule_timeout().
      
      Fix that by making it a signed long, and checking for negative value.

      [PATCH] Emulate deviceless bridge ioctls · 44fbe3d2
      Andi Kleen authored
      This helps vmware users running vmware on x86-64 - vmnet tries to set up a bridge.
      Emulate these ioctls. The bridge has more ioctls on its bridge device, but these
      don't seem to be needed here.

      [PATCH] Don't register disabled nodes · 2b82353a
      Andi Kleen authored
      Don't register disabled nodes.  Hits on x86-64 when there is a node with no memory.
      X86-64 shares this code with i386.

      [PATCH] Fix x86-64 32bit getdents for new glibc · a07b54e9
      Andi Kleen authored
      The newest CVS glibc assumes that Linux >=2.6.4 always passes d_type.
      This patch adds this to the 32bit getdents on x86-64 too
