    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • 559fde706   ibmvscsi: gadget: at91_udc: remove driver_data direct access of struct device ... Browse Code »

    In the near future, the driver core is going to not allow direct access
    to the driver_data pointer in struct device. Instead, the functions
    dev_get_drvdata() and dev_set_drvdata() should be used. These functions
    have been around since the beginning, so are backwards compatible with
    all older kernel versions.

    Calling crq_queue_create could lead to the creation of a rport. We
    need to set up everything before creating a rport. This moves
    crq_queue_create to the end of initialization to avoid a race which
    causes an oops if lost.

  • 8d8bb39b9   dma-mapping: add the device argument to dma_mapping_error() ... Browse Code »

    Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER
    architecture does:

    This enables us to cleanly fix the Calgary IOMMU issue that some devices
    are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423).

    I think that per-device dma_mapping_ops support would be also helpful for
    KVM people to support PCI passthrough but Andi thinks that this makes it
    difficult to support the PCI passthrough (see the above thread). So I
    CC'ed this to KVM camp. Comments are appreciated.

    A pointer to dma_mapping_ops to struct dev_archdata is added. If the
    pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's
    NULL, the system-wide dma_ops pointer is used as before.

    If it's useful for KVM people, I plan to implement a mechanism to register
    a hook called when a new pci (or dma capable) device is created (it works
    with hot plugging). It enables IOMMUs to set up an appropriate
    dma_mapping_ops per device.

    The major obstacle is that dma_mapping_error doesn't take a pointer to the
    device unlike other DMA operations. So x86 can't have dma_mapping_ops per
    device. Note all the POWER IOMMUs use the same dma_mapping_error function
    so this is not a problem for POWER but x86 IOMMUs use different
    dma_mapping_error functions.

    The first patch adds the device argument to dma_mapping_error. The patch
    is trivial but large since it touches lots of drivers and dma-mapping.h in
    all the architecture.

    This patch:

    dma_mapping_error() doesn't take a pointer to the device unlike other DMA
    operations. So we can't have dma_mapping_ops per device.

    Note that POWER already has dma_mapping_ops per device but all the POWER
    IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device
    argument.

  • bc7e380a6   [SCSI] tgt: fix sesnse buffer problems ... Browse Code »

    This patch simplify the way to notify LLDs of the command completion
    and addresses the following sense buffer problems:

    - can't handle both data and sense.
    - forces user-space to use aligned sense buffer

    tgt copies sense_data from userspace to cmnd->sense_buffer (if
    necessary), maps user-space pages (if necessary) and then calls
    host->transfer_response (host->transfer_data is removed).
