    …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.

  • 0a0300dc8   ARM: Consolidate clks_register() and similar ... Browse Code »

    Most machine classes want some way to register a block of clk_lookup
    structures, and most do it by implementing a clks_register() type
    function which walks an array, or by open-coding a loop.

    Consolidate all this into clkdev_add_table().

    This moves the mmci platform data definition struct away from
    arch/arm/include/asm/mach/mmc.h into the more proper place among
    the other primecells in include/linux/amba/mmci.h and at the same
    time renames it to "mmci.h", and also the struct in this file
    confusingly named mmc_platform_data has been renamed
    mmci_platform_data for clarity.

  • c07f87f22   [ARM] VIC: Add power management device ... Browse Code »

    Add power management support to the VIC by registering
    each VIC as a system device to get suspend/resume
    events going.

    Since the VIC registeration is done early, we need to
    record the VICs in a static array which is used to add
    the system devices later once the initcalls are run. This
    means there is now a configuration value for the number
    of VICs in the system.

  • be093beb6   [ARM] pass reboot command line to arch_reset() ... Browse Code »

    OMAP wishes to pass state to the boot loader upon reboot in order to
    instruct it whether to wait for USB-based reflashing or not. There is
    already a facility to do this via the reboot() syscall, except we ignore
    the string passed to machine_restart().

    This patch fixes things to pass this string to arch_reset(). This means
    that we keep the reboot mode limited to telling the kernel _how_ to
    perform the reboot which should be independent of what we request the
    boot loader to do.

  • dcea83adc   [ARM] Hide ISA DMA API when ISA_DMA_API is unset ... Browse Code »

    When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
    so there's no point in publishing the prototypes via asm/dma.h, nor
    including the machine dependent parts of that API.

    This allows us to remove a lot of mach/dma.h files which don't contain
    any useful code. Unfortunately though, some platforms put their own
    private non-ISA definitions into mach/dma.h, so we leave these behind
    and fix the appropriate #include statments.

  • 756813cac   [ARM] 4454/1: Use word accesses in Versatile PCI config reads ... Browse Code »

    ARM Versatile PCI config reads of one byte width have the lowest two
    bits of the address cleared and result in reading from a wrong place
    in the config space. This change is to use word size accesses like it is done for halfword reads.

    Byte reads are used for retrieving the IRQ number of a PCI device and the problem was not exposed until 2.6.20 because the value read was discarded in drivers/pci/setup-irq.c (recently fixed).
