    x86: Convert BUG() to use unreachable()

    David Daney authored torvalds committed
    Use the new unreachable() macro instead of for(;;);.  When
    allyesconfig is built with a GCC-4.5 snapshot on i686 the size of the
    text segment is reduced by 3987 bytes (from 6827019 to 6823032).

    Add support for GCC-4.5's __builtin_unreachable() to compiler.h (v2)

    David Daney authored torvalds committed
    Starting with version 4.5, GCC has a new built-in function
    __builtin_unreachable() that can be used in places like the kernel's
    BUG() where inline assembly is used to transfer control flow.  This
    eliminated the need for an endless loop in these places.
    
    The patch adds a new macro 'unreachable()' that will expand to either
    __builtin_unreachable() or an endless loop depending on the compiler
    version.
    
    Change from v1: Simplify unreachable() for non-GCC 4.5 case.

  4. x86, apic: Enable lapic nmi watchdog on AMD Family 11h

    Mikael Pettersson authored Ingo Molnar committed
    The x86 lapic nmi watchdog does not recognize AMD Family 11h,
    resulting in:
    
      NMI watchdog: CPU not supported
    
    As far as I can see from available documentation (the BKDM),
    family 11h looks identical to family 10h as far as the PMU
    is concerned.
    
    Extending the check to accept family 11h results in:
    
      Testing NMI watchdog ... OK.
    
    I've been running with this change on a Turion X2 Ultra ZM-82
    laptop for a couple of weeks now without problems.

  5. GFS2: Fix glock refcount issues

    Steven Whitehouse authored
    This patch fixes some ref counting issues. Firstly by moving
    the point at which we drop the ref count after a dlm lock
    operation has completed we ensure that we never call
    gfs2_glock_hold() on a lock with a zero ref count.
    
    Secondly, by using atomic_dec_and_lock() in gfs2_glock_put()
    we ensure that at no time will a glock with zero ref count
    appear on the lru_list. That means that we can remove the
    check for this in our shrinker (which was racy).

  6. writeback: remove unused nonblocking and congestion checks (gfs2)

    Wu Fengguang authored Steven Whitehouse committed
    No one is calling wb_writeback and write_cache_pages with
    wbc.nonblocking=1 any more. And lumpy pageout will want to do
    nonblocking writeback without the congestion wait.

  7. GFS2: drop rindex glock to refresh rindex list

    Benjamin Marzinski authored Steven Whitehouse committed
    When a gfs2 filesystem is grown, it needs to rebuild the rindex list to be able
    to use the new space.  gfs2 does this when the rindex is marked not uptodate,
    which happens when the rindex glock is dropped.  However, on a single node
    setup, there is never any reason to drop the rindex glock, so gfs2 never
    invalidates the the rindex. This patch makes gfs2 automatically drop the
    rindex glock after filesystem grows, so it can refresh the rindex list.

  8. GFS2: Tag all metadata with jid

    Steven Whitehouse authored
    There are two spare field in the header common to all GFS2
    metadata. One is just the right size to fit a journal id
    in it, and this patch updates the journal code so that each
    time a metadata block is modified, we tag it with the journal
    id of the node which is performing the modification.
    
    The reason for this is that it should make it much easier to
    debug issues which arise if we can tell which node was the
    last to modify a particular metadata block.
    
    Since the field is updated before the block is written into
    the journal, each journal should only contain metadata which
    is tagged with its own journal id. The one exception to this
    is the journal header block, which might have a different node's
    id in it, if that journal was recovered by another node in the
    cluster.
    
    Thus each journal will contain a record of which nodes recovered
    it, via the journal header.
    
    The other field in the metadata header could potentially be
    used to hold information about what kind of operation was
    performed, but for the time being we just zero it on each
    transaction so that if we use it for that in future, we'll
    know that the information (where it exists) is reliable.
    
    I did consider using the other field to hold the journal
    sequence number, however since in GFS2's journaling we write
    the modified data into the journal and not the original
    data, this gives no information as to what action caused the
    modification, so I think we can probably come up with a better
    use for those 64 bits in the future.

  10. GFS2: Remove dirent_first() function

    Steven Whitehouse authored
    This function only had one caller left, and that caller only
    called it for leaf blocks, hence one branch of the "if" was
    never taken. In addition the call to get_left had already
    verified the metadata type, so the function can be reduced
    to a single line of code in its caller.
