  • bd0b9ac40   genirq: Remove irq argument from irq flow handlers ... Browse Code »

    Most interrupt flow handlers do not use the irq argument. Those few
    which use it can retrieve the irq number from the irq descriptor.

    Remove the argument.

    Search and replace was done with coccinelle and some extra helper
    scripts around it. Thanks to Julia for her help!

    Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
    already have a pointer to corresponding irq_desc.

    Do the same change to avoid the pattern "irq_get_chip_data(data->irq)".

    Chained irq handlers usually set up handler data as well. We now have
    a function to set both under irq_desc->lock. Replace the two calls
    with one.

  • 9bd09f345   mfd: Kill off set_irq_flags usage ... Browse Code »

    set_irq_flags is ARM specific with custom flags which have genirq
    equivalents. Convert drivers to use the genirq interfaces directly, so we
    can kill off set_irq_flags. The translation of flags is as follows:

    IRQF_VALID -> !IRQ_NOREQUEST
    IRQF_PROBE -> !IRQ_NOPROBE
    IRQF_NOAUTOEN -> IRQ_NOAUTOEN

    For IRQs managed by an irqdomain, the irqdomain core code handles clearing
    and setting IRQ_NOREQUEST already, so there is no need to do this in
    .map() functions and we can simply remove the set_irq_flags calls. Some
    users also modify IRQ_NOPROBE and this has been maintained although it
    is not clear that is really needed. There appears to be a great deal of
    blind copy and paste of this code.

    "Here's the set of driver core patches for 3.19-rc1.

    They are dominated by the removal of the .owner field in platform

    Other than that, a few minor driver core and debugfs changes. There
    are some ath9k patches coming in through this tree that have been

    The driver core clears the driver data to NULL after device_release

    Thus, it is not needed to manually clear the device driver data to NULL.

  • 0848c94fb   mfd: core: Push irqdomain mapping out into devices ... Browse Code »

    Currently the MFD core supports remapping MFD cell interrupts using an
    irqdomain but only if the MFD is being instantiated using device tree
    and only if the device tree bindings use the pattern of registering IPs
    in the device tree with compatible properties. This will be actively
    harmful for drivers which support non-DT platforms and use this pattern
    for their DT bindings as it will mean that the core will silently change
    remapping behaviour and it is also limiting for drivers which don't do
    DT with this particular pattern. There is also a potential fragility if
    there are interrupts not associated with MFD cells and all the cells are
    omitted from the device tree for some reason.

    Instead change the code to take an IRQ domain as an optional argument,
    allowing drivers to take the decision about the parent domain for their
    interrupts. The one current user of this feature is ab8500-core, it has
    the domain lookup pushed out into the driver.

  • 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.

  • 0e820ab60   mfd: Correct use after free for t7l66xb ... Browse Code »

    The structure t7l66xb should not be freed before the subsequent references
    to its fields in the arguments to clk_put. Furthermore, this structure is
    allocated near the beginning of the function, and a goto to the label
    err_noirq appears after a successful allocation, so it would seem that the
    kfree should be moved down below this label.

    A simplified version of the semantic match that finds this problem is as
    follows: (http://coccinelle.lip6.fr/)
