      [PATCH] BSD accounting speedup · d24d1d3a
      Andrew Morton authored
      From: Ingo Molnar <mingo@elte.hu>
      
      Most distributions turn on process accounting - but even the common
      'accounting is off' case is horrible SMP-scalability-wise: it accesses a
      global spinlock during every sys_exit() call, which bounces like mad on SMP
      (and NUMA) systems.
      
      (i also got rid of the unused return code.)

      From: "lode leroy" <lode_leroy@hotmail.com>
      
      I would like to submit a trivial enhancement to display the ip address of
      the bootserver in /proc/net/pnp
      
      This aids me in developing a diskless linux root image to know where it

      [PATCH] xattr: fine-grained locking · 6abc05cc
      Andrew Morton authored
      From: Andreas Gruenbacher <agruen@suse.de>
      
      This patch removes the dependency on i_sem in the getxattr and
      listxattr iops of ext2 and ext3. In addition, the global ext[23]_xattr
      semaphores go away. Instead of i_sem and the global semaphore, mutual
      exclusion is now ensured by per-inode xattr semaphores, and by locking
      the buffers before modifying them. The detailed locking strategy is
      described in comments in fs/ext[23]/xattr.c.
      
      Due to this change it is no longer necessary to take i_sem in
      ext[23]_permission() for retrieving acls, so the
      ext[23]_permission_locked() functions go away.
      
      Additionally, the patch fixes a race condition in ext[23]_permission:
      Accessing inode->i_acl was protected by the BKL in 2.4; in 2.5 there no
      longer is such protection. Instead, inode->i_acl (and inode->i_default_acl)
      are now accessed under inode->i_lock. (This could be replaced by RCU in
      the future.)
      
      In the ext3 extended attribute code, an new uglines results from locking
      at the buffer head level: The buffer lock must be held between testing
      if an xattr block can be modified and the actual modification to prevent
      races from happening. Before a block can be modified,
      ext3_journal_get_write_access() must be called. But this requies an unlocked
      buffer, so I call ext3_journal_get_write_access() before locking the
      buffer. If it turns out that the buffer cannot be modified,
      journal_release_buffer() is called. Calling ext3_journal_get_write_access
      after the test but while the buffer is still locked would be much better.

      [PATCH] xattrr: preparation for fine-grained locking · 430cab6d
      Andrew Morton authored
      From: Andreas Gruenbacher <agruen@suse.de>
      
      Andrew Morton found that there is lock contention between extended
      attribute operations (like reading ACLs, which `ls -l' needs to do)
      and other operations on the same files. This is due to the fact that
      all extended attribute syscalls take inode->i_sem before calling into
      the filesystem code.
      
      To fix this problem, this patch no longer takes inode->i_sem in the
      getxattr and listxattr syscalls, and moves the lock taking code into
      the file systems. (Another patch improves the locking strategy in
      ext2 and ext3.)

      [PATCH] xattr: update-in-place optimisation · a39afa31
      Andrew Morton authored
      From: Andreas Gruenbacher <agruen@suse.de>
      
      It is common to update extended attributes without changing the value's
      length. This patch optimizes this case. In addition to that, the current
      code tries to recognize early when extended attribute blocks become
      empty. This optimization is not of significant value, so this patch
      removes it, and moves the empty block test further down.

      The inode->i_bdev field is not the same as inode->i_sb->s_bdev or bh->b_bdev.
      We must compare inode->i_sb->s_bdev with bh->b_bdev, or else equal extended
      attribute block will not be found.

      [PATCH] xattr: cleanups · 574dd596
      Andrew Morton authored
      From: From: Andreas Gruenbacher <agruen@suse.de>
      
      * Various minor cleanups and simplifications in the extended attributes
        and acl code.
      
      * Use a smarter shortcut rule in ext[23]_permission(): If the mask
        contains permissions that are not also contained in the group
        file mode permission bits, those permissions can never be granted by
        an acl. (The previous shortcut rule was more coarse.)

      [PATCH] use task_cpu() not ->thread_info->cpu in sched.c · 8ffcb67a
      Andrew Morton authored
      From: Mikael Pettersson <mikpe@csd.uu.se>
      
      This patch fixes two p->thread_info->cpu occurrences in kernel/sched.c to
      use the task_cpu(p) macro instead, which is optimised on UP.  Although one
      of the occurrences is under #ifdef CONFIG_SMP, it's bad style to use the
      raw non-optimisable form in non-arch code.

      [PATCH] shared library support for MMUless binfmt_flat loader · 3d97dc2d
      Greg Ungerer authored
      This patch adds shared library support to the MMU application
      loader, binfmt_flat. This is not new, it is a forward port from the
      same support in 2.4.x kernels with MMUless support, and has been
      running for well over a year now. The code support is conditionally
      compiled on CONFIG_BINFMT_FLAT_SHARED. This change also abstracts
      a bit more architecture dependent code into the separate flat.h
      includes.
      
      Basically relocations within an application also carry a tag to
      identify what they refer too (this code or which shared library).
      This is patched as before at load/run-time with an appropriate
      address.

      Simplify and speed up mmap read-around handling · 82a333fa
      Linus Torvalds authored
      This improves cold-cache program startup noticeably for me, and
      simplifies the read-ahead logic at the same time. The rules for
      read-ahead are:
      
       - if the vma is marked random, we just do the regular one-page case. 
         Obvious.
      
       - if the vma is marked "linear access", we use the regular readahead
         code. No change in behaviour there (well, we also only consider it a 
         _miss_ if it was marked linear access - the "readahead" and
         "readaround"  things are now totally independent of each other)
      
       - otherwise, we look at how many hits/misses we've had for this 
         particular file open for mmap, and if we've had noticeably more
         misses than hits, we don't bother with read-around.
      
      In particular, this means that the "real" read-ahead logic literally
      only needs to worry about finding sequential accesses, and does not
      have to worry about the common executable mmap access patthers that 
      have very different behaviour.
      
      Some constant tweaking may be a good idea.

      [PATCH] another timer overflow thing · e939c913
      Ingo Molnar authored
      in add_timer_internal() we simply leave the timer pending forever if the
      expiry is in more than 0xffffffff jiffies. This means more than 48 days on
      eg. ia64 - which is not an unrealistic timeout. IIRC crond is happy to use
      extremely large timeouts.
      
      It's better to time out early (if you can call 48 days "early") than to
      not time out at all.

      [PATCH] Fix do_div() for all architectures · f0a8aa74
      Bernardo Innocenti authored
      This offers a generic do_div64() that actually does the right thing,
      unlike some architectures that "optimized" the 64-by-32 divide into
      just a 32-bit divide.
      
      Both ppc and sh were already providing an assembly optimized
      __div64_32().  I called my function the same, so that their optimized
      versions will automatically override mine in lib.a.
      
      I've only tested extensively on m68knommu (uClinux) and made
      sure generated code is reasonably short. Should be ok also on
      parisc, since it's the same algorithm they were using before.
      
       - add generic C implementations of the do_div() for 32bit and 64bit
         archs in asm-generic/div64.h;
      
       - add generic library support function __div64_32() to handle the
         full 64/32 case on 32bit archs;
      
       - kill multiple copies of generic do_div() in architecture
         specific subdirs. Most copies were either buggy or not doing
         what they were supposed to do;
      
       - ensure all surviving instances of do_div() have their parameters
         correctly parenthesized to avoid funny side-effects;
