      [PATCH] Improve laptop mode's block_dump output · 6835de14
      Andrew Morton authored
      From: "Theodore Ts'o" <tytso@mit.edu>
      
      This patch versus improves the output produced by "echo 1 >
      /proc/sys/vm/block_dump", in the following ways:
      
      1) The messages are printed with KERN_DEBUG, so that even if sysklogd is
         running, if configured appropriately, it will not need to write to log
         files.
      
      2) The inode which is dirtied by a process is now identified more
         precisely by inode number and filesystem ID, and by a dcache name if
         present.
      
      3) In the generic filesystem sget function, the superblock id (s_id) is
         filled in with the filesystem type by default.  Filesystems which are
         block-device based will override s_id, but this allows pseudo
         filesystems such as tmpfs, procfs, etc.  to be identified in (2).

      [PATCH] find_user locking and leak fix · 475c3656
      Andrew Morton authored
      find_user() is being called from set/get_priority(), but it doesn't take the
      needed lock, and those callers were forgetting to drop the refcount which
      find_user() took.

      which filesystem triggers the message.  Loosely based on code from Oleg
      Drokin.

      This patch from Micha Feigin fixes some bugs in the earlier reiserfs 
      commit default patch. The changelog:
      
      * If you remounted without any commit=NNN option, it would assume commit=0
        and restore the defaults.  This patch makes it leave the current state alone
        if you don't pass commit=NNN.
      
      * Added range check for cast from unsigned long to unsigned int.

      [PATCH] shrink_slab: improved handling of GFP_NOFS allocations · edb41998
      Andrew Morton authored
      Currently, shrink_slab() will decide that it needs to scan a certain number of
      dentries, will call shrink_dcache_memory() requesting that this be done, and
      shrink_dcache_memory() will simply bale out without doing anything because the
      caller did not have __GFP_FS.
      
      This has the potential to disrupt our lovely pagecache-vs-slab balancing act. 
      So change things so that shrinker callouts can return -1, indicating that they
      baled out.  This way, shrink_slab can remember that this slab was owed a
      certain number of scannings and these will be correctly performed next time a
      __GFP_FS caller comes by.

      [PATCH] New version of early CPU detect · b528cea7
      Andrew Morton authored
      From: Andi Kleen <ak@suse.de>
      
      We still need some kind of early CPU detection, e.g.  for the AMD768
      workaround and for the slab allocator to size its slabs correctly for the
      cache line.  Also some other code already had private early CPU routines.
      
      This patch takes a new approach compared to the previous patch which caused
      Andrew so much grief.  It only fills in a few selected fields in
      boot_cpu_data (only the data needed to identify the CPU type and the cache
      alignment).  In particular the feature masks are not filled in, and the
      other fields are also not touched to prevent unwanted side effects.
      
      Also convert the ppro workaround to use standard cpu data now. 
      
      I'm not sure if slab still has the necessary support to use the cache line
      size early; previously Manfred showed some serious memory saving with this
      for kernels that are compiled for a bigger cache line size than the CPU (is
      often the case on distribution kernels).  This code could be reenable now
      with this patch.

      [PATCH] es7000 subarch update · 45dc4f27
      Andrew Morton authored
      From: "Protasevich, Natalie" <Natalie.Protasevich@UNISYS.com>
      
      The patch fixes a problem with ES7000 Server Management mechanism that uses
      platform register mip_port.  It was not initialized, so the mechanism was not
      functional.
      
      The patch also fixes the APIC destination for hierarchical and flat cluster
      models used in ES7000.  The destination ID's reflect policies for Cascade
      based systems which use logical delivery and lowest priority mechanism, and
      for xAPIC based models that use physical delivery and fixed APIC destinations.
      
      The patch also turns on NO_IOAPIC_CHECK (1) to avoid error messages and
      attempts to re-write the ID, because on ES7000 all ID's are hard coded in the
      BIOS and cannot be altered.

      [PATCH] Consolidate sys32_nfsservctl · 522cbd42
      Andrew Morton authored
      From: Arnd Bergmann <arnd@arndb.de>
      
      sys32_nfsservctl is the largest remaining syscall emulation handler that can
      be consolidated.  mips and ia64 currently don't use this at all, parisc has a
      simpler implementation than the one used by s390, sparc ppc and that the new
      compat_sys_nfsservctl is based on.
      
      The user access checks in the code are inconsistant at least, which should be
      fixed here.
      
      Compile tested only due to lack of proper test setup.

      sys32_select has seven mostly but not exactly identical versions, so
      consolidate them as compat_sys_select.  Based on the ppc64 implementation,
      which most closely resembles sys_select.  One bug that was not caught by LTP
      has been fixed since the first version of this patch.

      from fs/exec.c but not kept up-to-date.  The new compat_do_execve() function

      [PATCH] selinux: reopen descriptors closed on exec to /dev/null · def3f08e
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch changes the SELinux module to try to reset any descriptors it
      closes on exec (due to a lack of permission by the new domain to the inherited
      open file) to refer to the null device.  This counters the problem of SELinux
      inducing program misbehavior, particularly due to having descriptors 0-2
      closed when the new domain is not allowed access to the caller's tty.  This is
      primarily to address the case where the caller is trusted with respect to the
      new domain, as the untrusted caller case is already handled via AT_SECURE and
      glibc secure mode.  The code is partly based on the OpenWall LSM, which in
      turn drew from the OpenWall kernel patch.  Note that the code does not
      guarantee that the descriptor is always re-opened to /dev/null; it merely
      makes a reasonable effort to do so, but can fail under various conditions.

      [PATCH] ext3 error handling fixes · e461abeb
      Andrew Morton authored
      From: Andreas Dilger <adilger@clusterfs.com>
      
      a) we don't call ext3_error() for an IO error in ext3_find_entry(), so we
         won't do the normal ext3 error handling (mark SB in error, remount-ro
         or panic if desired);
      b) in empty_dir() we don't continue checking for non-empty blocks after a
         content error (ext3_check_dir_entry() calls ext3_error() already);
      c) we had decided not to mark the SB in error for holes in directories to
         allow leway in the indexed-directory implementation, but this change
         incorrectly also disabled marking the SB in error for real IO errors.

      [PATCH] Fix ext3 bogus ENOSPC · e736428d
      Andrew Morton authored
      With strange workloads which do a lot of quick truncation on small filesystems
      it is possible to get into a situation where there are free blocks on the
      disk, but they are not allocatable at this time due to their having been freed
      up in the current JBD transaction.  Applications get unexpected ENOSPC errors.
      
      We can fix that with this patch, originally by Andreas Dilger which forces a
      single commit+retry when an ENOSPC is encountered.

      [PATCH] reduce NMI watchdog call frequency with local APIC. · 774882ea
      Andrew Morton authored
      From: Mikael Pettersson <mikpe@csd.uu.se>
      
      The real problem is that SMP with nmi_watchdog=2 initialises the lapic NMI
      watchdog but doesn't check it and therefore doesn't reduce nmi_hz.  This is
      an SMP bug.
      
      The patch changes smpboot.c to do a check_nmi_watchdog() at the appropriate
      place, which fixes the high NMI frequency problem w/o changing anything
      else.  I've verified that it solves the problem on my MP-capable UP box.

      With nmi_watchdog=2 and a P4 ht box the nmi is occurring only on logical

      With this patch, on x86 SMP and nmi_watchdog=2, nmi interupts occur at 1000
      hz (if the cpu is loaded) not at the intended 1 hz rate but that's a distinct
      problem.

      The following scenarios discuss the race conditions:
      
      1) When the search is hapenning, if any ioctl_trans structure gets
         deleted; then rather than searching the hash table, the code will start
         searching the free list.
