  • Fix this section mismatch:

    WARNING: drivers/misc/ioc4.o(.data+0x144): Section mismatch in reference from the variable ioc4_load_modules_work to the function .devinit.text:ioc4_load_modules()
    The variable ioc4_load_modules_work references
    the function __devinit ioc4_load_modules()
    If the reference is valid then annotate the
    variable with __init* or __refdata (see linux/init.h) or name the variable:
    *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

    This one is potentially fatal; by the time ioc4_load_modules is invoked
    it may already have been freed. For that reason ioc4_load_modules_work
    can't be turned to __devinitdata but also because it's referenced in
    ioc4_exit.

  • There is no reason to dynamically allocate work_struct for
    ioc4_load_modules(). It makes the code more complex and makes it
    impossible to flush the work directly. Use static work
    ioc4_load_modules_work instead and flush it directly on exit.

    This removes the use of flush_scheduled_work() which is being
    deprecated.

  • …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.

  • Several IOC3 and IOC4 drivers misuse the __devinit and __devexit section
    markers. Use __init and __exit instead as appropriate, then add __devinit
    and __devexit where they really belong for PCI drivers.

    Also make ioc4_serial_init static.

  • Modify ioc4 to always load the sgiioc4 IDE module if the board carrying
    the IOC4 hardware actually implements the IDE interface (not all boards
    bring this functionality off the IOC4 chip). A drive hosted on the IDE
    interface may contain the root filesystem, and sgiioc4 doesn't load
    automatically as ioc4 owns the PCI device ID, not sgiioc4.

  • The SGI PCI-RT card, based on the SGI IOC4 chip, will be made available on
    Altix XE (x86_64) platforms in the near future. As such it is now a
    misnomer for the IOC4 base device driver to live under drivers/sn, and
    would complicate builds for non-SN2.

    This patch moves the IOC4 base driver code from drivers/sn to drivers/misc,
    and updates the associated Makefiles and Kconfig files to allow building on
    non-SN2 configs. Due to the resulting change in link order, it is now
    necessary to use late_initcall() for IOC4 subdriver initialization.
