  • 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.

  • 48a048fed   cpumask: arch_send_call_function_ipi_mask: mips ... Browse Code »

    We're weaning the core code off handing cpumask's around on-stack.
    This introduces arch_send_call_function_ipi_mask(), and by defining
    it, the old arch_send_call_function_ipi is defined by the core code.

    We also take the chance to wean the implementations off the
    obsolescent for_each_cpu_mask(): making send_ipi_mask take the pointer
    seemed the most natural way to ensure all implementations used
    for_each_cpu.

  • 0ca71737f   MIPS: Simplify and correct interrupt handling for MSP4200 ... Browse Code »

    The current interrupt handling code for the MSP4200 always masks an
    interrupt before acknowledging it. This is not required, as that will be
    handled by the level interrupt handler. This change simplifies the MSP4200
    code to remove the masking in the ack routine, and makes sure that the
    minimum required operation is performed for masking and acking, rather
    than always both masking and acking the interrupt.

    Trying to build MSP4200 VoIP defconfig also fails on msp_irq_slp.c with a

  • 98a79d6a5   cpumask: centralize cpu_online_map and cpu_possible_map ... Browse Code »

    Impact: cleanup

    Each SMP arch defines these themselves. Move them to a central
    location.

    Twists:
    1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a
    CONFIG_INIT_ALL_POSSIBLE for this rather than break them.

    2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
    Those archs simply have phys_cpu_present_map replaced everywhere.

    3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky
    so I just manipulate them both in sync.

    4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map'
    declarations.

  • 0aea53132   PCI: remove unused arch pcibios_update_resource() functions ... Browse Code »

    Russell King did the following back in 2003:

    [PCI] pci-9: Kill per-architecture pcibios_update_resource()

    Kill pcibios_update_resource(), replacing it with pci_update_resource().
    pci_update_resource() uses pcibios_resource_to_bus() to convert a
    resource to a device BAR - the transformation should be exactly the
    same as the transformation used for the PCI bridges.

    pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to
    set the high 32-bits to anything non-zero - currently no architecture
    attempts to do something different. If anyone cares, please fix; I'm
    going to reflect current behaviour for the time being.

    Ivan pointed out the following architectures need to examine their
    pcibios_update_resource() implementation - they should make sure that
    this new implementation does the right thing. #warning's have been
    added where appropriate.

    ia64
    mips
    mips64

    This cset also includes a fix for the problem reported by AKPM where
    64-bit arch compilers complain about the resource mask being placed
    in a u32.

    This patch removes the unused pcibios_update_resource() functions the
    kernel gained since, from FRV, m68k, mips & sh architectures.
