  • ef24ba709   powerpc: Remove all usages of NO_IRQ ... Browse Code »

    NO_IRQ has been == 0 on powerpc for just over ten years (since commit
    0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change
    platforms to use it")). It's also 0 on most other arches.

    Although it's fairly harmless, every now and then it causes confusion
    when a driver is built on powerpc and another arch which doesn't define
    NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least
    some of which are to work around that problem.

    So we'd like to remove it. This is fairly trivial in the arch code, we
    just convert:

    if (irq == NO_IRQ) to if (!irq)
    if (irq != NO_IRQ) to if (irq)
    irq = NO_IRQ; to irq = 0;
    return NO_IRQ; to return 0;

    And a few other odd cases as well.

    At least for now we keep the #define NO_IRQ, because there is driver
    code that uses NO_IRQ and the fixes to remove those will go via other
    trees.

    Note we also change some occurrences in PPC sound drivers, drivers/ps3,
    and drivers/macintosh.

  • 4a8bb7f54   ps3-vuart: don't use PREPARE_WORK ... Browse Code »

    PREPARE_[DELAYED_]WORK() are being phased out. They have few users
    and a nasty surprise in terms of reentrancy guarantee as workqueue
    considers work items to be different if they don't have the same work
    function.

    ps3_vuart wasn't overriding the work item with multiple work functions
    but was using NULL for INIT_WORK() and then single PREPARE_WORK() to
    set the work function. We can simply invoke INIT_WORK() with the work
    function and remove the PREPARE_WORK() usage.

    It would probably be best to route this with other related updates
    through the workqueue tree.

    Geoff: Tested on ps3 (DECR-1400).

  • 0fe763c57   Drivers: misc: remove __dev* attributes. ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
    markings need to be removed.

    This change removes the use of __devinit, __devexit_p, __devinitdata,
    __devinitconst, and __devexit from these drivers.

    Based on patches originally written by Bill Pemberton, but redone by me
    in order to handle some of the coding style issues better, by hand.

  • 6ea741a13   powerpc/ps3: irq: Remove IRQF_DISABLED ... Browse Code »

    Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
    We run all interrupt handlers with interrupts disabled
    and we even check and yell when an interrupt handler
    returns with interrupts enabled (see commit [b738a50a:
    genirq: Warn when handler enables interrupts]).

    So now this flag is a NOOP and can be removed.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …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.

    A workaround for flash memory I/O errors when the PS3 internal
    hard disk has not been formatted for OtherOS use.

    This error condition mainly effects 'Live CD' users who have not
    formatted the PS3's internal hard disk for OtherOS.

    Fixes errors similar to these when using the ps3-flash-util
    or ps3-boot-game-os programs:

    ps3flash read failed 0x2050000
    os_area_header_read: read error: os_area_header: Input/output error
    main:627: os_area_read_hp error.

    This fixes it. We have to include rather than
