    Merge tag 'split-asm_system_h-for-linus-20120328' of 
git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system
    
    Pull "Disintegrate and delete asm/system.h" from David Howells:
     "Here are a bunch of patches to disintegrate asm/system.h into a set of
      separate bits to relieve the problem of circular inclusion
      dependencies.
    
      I've built all the working defconfigs from all the arches that I can
      and made sure that they don't break.
    
      The reason for these patches is that I recently encountered a circular
      dependency problem that came about when I produced some patches to
      optimise get_order() by rewriting it to use ilog2().
    
      This uses bitops - and on the SH arch asm/bitops.h drags in
      asm-generic/get_order.h by a circuituous route involving asm/system.h.
    
      The main difficulty seems to be asm/system.h.  It holds a number of
      low level bits with no/few dependencies that are commonly used (eg.
      memory barriers) and a number of bits with more dependencies that
      aren't used in many places (eg.  switch_to()).
    
      These patches break asm/system.h up into the following core pieces:
    
        (1) asm/barrier.h
    
            Move memory barriers here.  This already done for MIPS and Alpha.
    
        (2) asm/switch_to.h
    
            Move switch_to() and related stuff here.
    
        (3) asm/exec.h
    
            Move arch_align_stack() here.  Other process execution related bits
            could perhaps go here from asm/processor.h.
    
        (4) asm/cmpxchg.h
    
            Move xchg() and cmpxchg() here as they're full word atomic ops and
            frequently used by atomic_xchg() and atomic_cmpxchg().
    
        (5) asm/bug.h
    
            Move die() and related bits.
    
        (6) asm/auxvec.h
    
            Move AT_VECTOR_SIZE_ARCH here.
    
      Other arch headers are created as needed on a per-arch basis."
    
    Fixed up some conflicts from other header file cleanups and moving code
    around that has happened in the meantime, so David's testing is somewhat
    weakened by that.  We'll find out anything that got broken and fix it..

    Merge branch 'for-linus' of git://oss.sgi.com/xfs/xfs
    
    Pull XFS update (part 2) from Ben Myers:
     "Fixes for tracing of xfs_name strings, flag handling in
      open_by_handle, a log space hang with freeze/unfreeze, fstrim offset
      calculations, a section mismatch with xfs_qm_exit, an oops in
      xlog_recover_process_iunlinks, and a deadlock in xfs_rtfree_extent.
    
      There are also additional trace points for attributes, and the
      addition of a workqueue for allocation to work around kernel stack
      size limitations."

    Merge branch 'for-linus' of git://oss.sgi.com/xfs/xfs
    
    Pull XFS updates from Ben Myers:
     "Scalability improvements for dquots, log grant code cleanups, plus
      bugfixes and cleanups large and small"
    
    Fix up various trivial conflicts that were due to some of the earlier
    patches already having been integrated into v3.3 as bugfixes, and then
    there were development patches on top of those.  Easily merged by just
    taking the newer version from the pulled branch.

commit 8de52778798fe39660a8d6b26f290e0c93202761
Author: Al Viro <viro@xxxxxxxxxxxxxxxxxx>
Date:   Mon Feb 6 12:45:27 2012 -0500

    vfs: check i_nlink limits in vfs_{mkdir,rename_dir,link}
    
    New field of struct super_block - ->s_max_links.  Maximal allowed
    value of ->i_nlink or 0; in the latter case all checks still need
    to be done in ->link/->mkdir/->rename instances.  Note that this
    limit applies both to directoris and to non-directories.
