  • 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.

  • d7646f763   pcmcia: use dev_pm_ops for class pcmcia_socket_class ... Browse Code »

    Instead of requiring PCMCIA socket drivers to call various functions
    during their (bus) resume and suspend functions, register an own
    dev_pm_ops for this class. This fixes several suspend/resume bugs
    seen on db1xxx-ss, and probably on some other socket drivers, too.

    With regard to the asymmetry with only _noirq suspend, but split up
    resume, please see bug 14334 and commit 9905d1b411946fb3 .

  • 11b897cf8   MIPS: Alchemy: use 36bit addresses for PCMCIA resources. ... Browse Code »

    On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus
    area. Currently, addresses at the far end of the 32bit area are assumed
    to belong to the PCMCIA area and fixed up to the real 36bit address before
    being passed to ioremap().

    A previous commit enabled 64 bit physical size for the resource datatype on
    Alchemy and this allows to use the correct 36bit addresses when registering
    the PCMCIA sockets.

    This patch removes the 32-to-36bit address fixup and registers the Alchemy
    demo board pcmcia socket with the correct 36bit physical addresses.

    Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet
    card.

  • 7a192ec33   platform driver: fix incorrect use of 'platform_bus_type' with 'struct device_driver' ... Browse Code »

    This patch fixes the bug reported in
    http://bugzilla.kernel.org/show_bug.cgi?id=11681.

    "Lots of device drivers register a 'struct device_driver' with
    the '.bus' member set to '&platform_bus_type'. This is wrong,
    since the platform_bus functions expect the 'struct device_driver'
    to be wrapped up in a 'struct platform_driver' which provides
    some additional callbacks (like suspend_late, resume_early).
    The effect may be that platform_suspend_late() uses bogus data
    outside the device_driver struct as a pointer pointer to the
    device driver's suspend_late() function or other hard to
    reproduce failures."(Lothar Wassmann)

    The previous code did something like,

    if (error) goto out_err;
    ....
    do {
    struct au1000_pcmcia_socket *skt = PCMCIA_SOCKET(i);
    del_timer_sync(&skt->poll_timer);

    out_err:
    flush_scheduled_work();
    ops->hw_shutdown(skt);
    i--;
    } while (i > 0)
    .....

    - On the error path, skt would not contain a valid value for the first
    iteration (skt is masked by uninitialized automatic skt)

    - Does not do hw_shutdown() for 0th element of PCMCIA_SOCKET

  • 9480e307c   [PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacks ... Browse Code »

    In PM v1, all devices were called at SUSPEND_DISABLE level. Then
    all devices were called at SUSPEND_SAVE_STATE level, and finally
    SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
    compatibility for platform devices, I arranged for the PM v2
    suspend/resume callbacks to call the old PM v1 suspend/resume
    callbacks three times with each level in order so that existing
    drivers continued to work.

    Since this is obsolete infrastructure which is no longer necessary,
    we can remove it. Here's an (untested) patch to do exactly that.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
