    [PATCH] SCX200_ACB: eliminate spurious timeout errors

    dwmw2 committed with Linus Torvalds
    While busy-waiting for completion, check the hardware after scheduling;
    don't schedule and then immediately check the _timeout_.  If the yield()
    took a long time (as it does on my OLPC prototype board when it's busy),
    we'd report a timeout even though the hardware was now ready.
    
    This fixes it, and also switches the yield() for a cond_resched() because
    we don't actually want to be _that_ nice about it.  I see nice
    tightly-packed SMBus transactions now, rather than waiting for milliseconds
    between successive phases.
    
    Actually, we shouldn't be busy-waiting here at all.  We should be using
    interrupts.  That's an exercise for another day though.

    [PATCH] udf: initialize parts of inode earlier in create

    sandeen committed with Linus Torvalds
    I saw an oops down this path when trying to create a new file on a UDF
    filesystem which was internally marked as readonly, but mounted rw:
    
    udf_create
            udf_new_inode
                    new_inode
                            alloc_inode
                            	udf_alloc_inode
                    udf_new_block
                            returns EIO due to readonlyness
                    iput (on error)
                            udf_put_inode
                                    udf_discard_prealloc
                                            udf_next_aext
                                                    udf_current_aext
                                                            udf_get_fileshortad
                                                                    OOPS
    
    the udf_discard_prealloc() path was examining uninitialized fields of the
    udf inode.
    
    udf_discard_prealloc() already has this code to short-circuit the discard
    path if no extents are preallocated:
    
            if (UDF_I_ALLOCTYPE(inode) == ICBTAG_FLAG_AD_IN_ICB ||
                    inode->i_size == UDF_I_LENEXTENTS(inode))
            {
                    return;
            }
    
    so if we initialize UDF_I_LENEXTENTS(inode) = 0 earlier in udf_new_inode,
    we won't try to free the (not) preallocated blocks, since this will match
    the i_size = 0 set when the inode was initialized.

    [PATCH] pnpacpi: reject ACPI_PRODUCER resources

    mat-c committed with Linus Torvalds
    A patch in -mm kernel correct the parsing of "address resources" of pnpacpi.
    Before we assumed it was memory only, but it could be also IO.
    
    But this change show an hidden bug : some resources could be producer type
    that are not handled by pnp layer.  So we should ignore the producer
    resources.
    
    This patch fixes bug 6292 (http://bugzilla.kernel.org/show_bug.cgi?id=6292).
    Some devices like PNP0A03 have 0xd00-0xffff and 0x0-0xcf7 as IO producer
    resources.
    
    Before correcting "address resources" parsing, it was seen as memory and was
    harmless, because nobody tried to reserve this memory range as it should be
    IO.
    
    With the correction it become IO resources, and make failed all others device
    that want to register IO in this range and use pnp layer (like a ISA sound
    card).
    
    The solution is to ignore producer resources

  9. [PATCH] reiserfs_write_full_page() should not get_block past eof

    Chris Mason committed with Linus Torvalds
    reiserfs_write_full_page does zero bytes in the file past eof, but it may
    call get_block on those buffers as well.  On machines where the page size
    is larger than the blocksize, this can result in mmaped files incorrectly
    growing up to a block boundary during writepage.
    
    The fix is to avoid calling get_block for any blocks that are entirely past
    eof

    [PATCH] memory hotadd fixes: enhance collision check

    hkamezawa committed with Linus Torvalds
    This patch is for collision check enhancement for memory hot add.
    
    It's better to do resouce collision check before doing memory hot add,
    which will touch memory management structures.
    
    And add_section() should check section exists or not before calling
    sparse_add_one_section(). (sparse_add_one_section() will do another
    check anyway. but checking in memory_hotplug.c will be easy to understand.)

    add_memory() does all necessary check to avoid collision.  then, acpi layer
    doesn't have to check region by itself.
    
    (*) pfn_valid() just returns page struct is valid or not. It returns 0
        if a section has been already added even is ioresource is not added.
        ioresource collision check in mm/memory_hotplug.c can do more precise
        collistion check.

    hkamezawa committed with Linus Torvalds
    ioresouce handling code in memory hotplug allows not-aligned memory hot add.
    But when memmap and other memory structures are initialized, parameters should
    be aligned.  (if not aligned, initialization of mem_map will do wrong, it
    assumes parameters are aligned.) This patch fix it.

  17. [PATCH] Fix BeFS slab corruption

    Diego Calleja committed with Linus Torvalds
    In bugzilla #6941, Jens Kilian reported:
    
    "The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the
    end of a block of memory allocated via kmalloc(), leading to memory
    corruption.  This happens only for filenames which are pure ASCII and a
    multiple of 4 bytes in length.  [...]
    
    Without DEBUG_SLAB, this leads to further corruption and hard lockups; I
    believe this is the bug which has made kernels later than 2.6.8 unusable
    for me.  (This must be due to changes in memory management, the bug has
    been in the BeFS driver since the time it was introduced (AFAICT).)
    
    Steps to reproduce:
    Create a directory (in BeOS, naturally :-) with files named, e.g.,
    "1", "22", "333", "4444", ...  Mount it in Linux and do an "ls" or "find""
    
    This patch implements the suggested fix. Credits to Jens Kilian for
    debugging the problem and finding the right fix.

    …pc auth cache
    
    If we don't find the item we are lookng for, we allocate a new one, and
    then grab the lock again and search to see if it has been added while we
    did the alloc.  If it had been added we need to 'cache_put' the newly
    created item that we are never going to use.  But as it hasn't been
    initialised properly, putting it can cause an oops.
    
    So move the ->init call earlier to that it will always be fully initilised
    if we have to put it.

    gets around to reading or writing it.
    
    However for reasons which aren't obvious (or sane?) I mapped
    POSIX_FADV_NOREUSE onto POSIX_FADV_WILLNEED.  ie: it does readahead.
    
    That's daft.  So for now, make POSIX_FADV_NOREUSE a no-op.
    
    This is a non-back-compatible change.  If someone was using POSIX_FADV_NOREUSE
    to perform readahead, they lose.  The likelihood is low.
    
    If/when we later implement POSIX_FADV_NOREUSE things will get interesting - to
    do it fully we'll need to maintain file offset/length ranges and peform all
    sorts of complex tricks, and managing the lifetime of those ranges' data
    structures will be interesting..
    
    A sensible implementation would probably ignore the file range and would
    simply mark the entire file as needing some form of drop-behind treatment.

    Rodolfo Giometti committed with Linus Torvalds
    - fix up the start up sequence.
    
    This new sequence allow you to correctly enable the LCD controller
    even if the bootloader has already did it.
    
    - fix up a wrong indentation issue.

    Reported by: Dave Jones
    
    Whilst printk'ing to both console and serial console, I got this...
    (2.6.18rc1)
    
    BUG: sleeping function called from invalid context at kernel/sched.c:4438
    in_atomic():0, irqs_disabled():1
    
    Call Trace:

    This can occur when release_console_sem() is called but the log
    buffer still has contents that need to be flushed. The console drivers
    are called while the console_may_schedule flag is still true. The
    might_sleep() is triggered when fbcon calls console_conditional_schedule().
    
    Fix by setting console_may_schedule to zero earlier, before the call to the
    console drivers.

    When delivering PTRACE_EVENT_VFORK_DONE, provide pid of the child process
    when tracer calls ptrace(PTRACE_GETEVENTMSG).  This is already
    (accidentally) available when the tracer is tracing VFORK in addition to
    VFORK_DONE.

    [PATCH] md: Fix a bug that recently crept into md/linear

    neilbrown committed with Linus Torvalds
    A recent patch that allowed linear arrays to be reconfigured on-line
    allowed in a bug which results in divide by zero - not all
    mddev->array_size were converted to conf->array_size.
    
    This patch finished the conversion and fixed the bug.
    
    The offending patch was commit 7c7546c.
    
    Thanks to Simon Kirby <sim@netnation.com> for the bug report.
