    MN10300: Change the fault handler to check in_atomic() not in_interrupt()
    
    Change the MN10300 fault handler to make it check in_atomic() rather than
    in_interrupt() as commit 6edaf68a87d17570790fd55f0c451a29ec1d6703 did for other
    architectures:

    	[PATCH] mm: arch do_page_fault() vs in_atomic()
    
    	In light of the recent pagefault and filemap_copy_from_user work I've
    	gone through all the arch pagefault handlers to make sure the
    	inc_preempt_count() 'feature' works as expected.
    
    	Several sections of code (including the new filemap_copy_from_user)
    	rely on the fact that faults do not take locks under increased preempt
    	count.

    block: disable sysfs parts of the disk command filter
    
    We still have life time issues with the sysfs command filter kobject,
    so disable it for 2.6.27 release. We can revisit this and make it work
    properly for 2.6.28, for 2.6.27 release it's too risky.

    KVM: SVM: fix guest global tlb flushes with NPT
    
    Accesses to CR4 are intercepted even with Nested Paging enabled. But the code
    does not check if the guest wants to do a global TLB flush. So this flush gets
    lost. This patch adds the check and the flush to svm_set_cr4.

    KVM: SVM: fix random segfaults with NPT enabled
    
    This patch introduces a guest TLB flush on every NPF exit in KVM. This fixes
    random segfaults and #UD exceptions in the guest seen under some workloads
    (e.g. long running compile workloads or tbench). A kernbench run with and
    without that fix showed that it has a slowdown lower than 0.5%

    VIDEO_SH_MOBILE_CEU, which selects VIDEOBUF_DMA_CONTIG. This circumvents the

    swiotlb: fix back-off path when memory allocation fails
    
    This fixes a SWIOTLB oops
    
    With SWIOTLB being enabled and straight-forward page allocation
    failure [1], the swiotlb_alloc_coherent fall-back path hits an
    issue [2], resulting in my webcam failing to work.
    
    At the time of oops, RDI is clearly a pointer to a structure which
    has arrived as NULL, leading to the typo in swiotlb_map_single's
    callsite arguments.
    
    Correctly passing the device structure [3] addresses the issue and
    gets my webcam working again (the allocation failure still occuring).

    ide: Fix pointer arithmetic in hpt3xx driver code (3rd try)
    
    git commit 74811f355f4f69a187fa74892dcf2a684b84ce99 causes crash at
    module load (or boot) time on my machine with a hpt374 controller.
    The reason for this is that for initializing second controller which sets
    (hwif->dev == host->dev[1]) to true (1), adds 1 to a void ptr, which
    advances it by one byte instead of advancing it by sizeof(hpt_info) bytes.
    Because of this, all initialization functions get corrupted data in info
    variable which causes a crash at boot time.
    
    This patch fixes that and makes my machine boot again.
    
    The card itself is a HPT374 raid conroller: Here is the lspci -v output:

    ocfs2: Fix a bug in direct IO read.
    
    ocfs2 will become read-only if we try to read the bytes which pass
    the end of i_size. This can be easily reproduced by following steps:
    1. mkfs a ocfs2 volume with bs=4k cs=4k and nosparse.
    2. create a small file(say less than 100 bytes) and we will create the file
       which is allocated 1 cluster.
    3. read 8196 bytes from the kernel using O_DIRECT which exceeds the limit.
    4. The ocfs2 volume becomes read-only and dmesg shows:
    OCFS2: ERROR (device sda13): ocfs2_direct_IO_get_blocks:
    Inode 66010 has a hole at block 1
    File system is now read-only due to the potential of on-disk corruption.
    Please run fsck.ocfs2 once the file system is unmounted.
    
    So suppress the ERROR message.

    [SCSI] fix check of PQ and PDT bits for WLUNs
    
    For IBM z series certain LUNs can no longer be accessed.
    
    This is because kernel version 2.6.19 a check was introduced not to
    create a generic SCSI device for devices that return PQ=1 and
    PDT=0x1f. For WLUNs (see SAM-3, p. 41ff) generic SCSI devices should
    be created unconditionally without looking at the PQ bit, so add a
    check for WLUNs in with this test.

    A memory allocation inside alloc_mutex must not recurse back into the

    alloc_mutex (and thus to deadlocks - see traces below). alloc_mutex is actually
    needed only to update allocation statistics in the superblock so we can drop it
    before we start allocating memory for the inode.
