    Subjecthardirq.h removal broke sparc64 build...

    [ Andrew, read carefully, I think some part of a patch you
    merged might have been lost while reshuffling or whatever. ]

    This change:

    commit ba84be2338d3a2b6020d39279335bb06fcd332e1
    Author: Russell King <>
    Date: Tue Jan 6 14:41:07 2009 -0800

    remove linux/hardirq.h from asm-generic/local.h

    broke the build on sparc64:

    drivers/base/topology.c: In function ‘show_physical_package_id’:
    drivers/base/topology.c:103: error: implicit declaration of function ‘cpu_data’
    drivers/base/topology.c:103: error: request for member ‘proc_id’ in something not a structure or union
    drivers/base/topology.c: In function ‘show_core_id’:
    drivers/base/topology.c:106: error: request for member ‘core_id’ in something not a structure or union

    Even though there is a footnote there from Alexey saying that
    sparc64 was fixed up :-)

    [ fix sparc64]

    I've spent most of last night and this morning trying to figure out
    a way to fix this, it is very non-trivial.

    Adding a simple asm/cpudata.h include into asm/topology_64.h for the
    SMP case does not work.

    asm/cpudata.h brings in percpu.h which wants SLAB which wants to use
    GFP_* values and thus includes gfp.h

    And thus because of the include loop:

    linux/gfp.h --> linux/mmzone.h --> linux/topology.h -->
    asm/topology.h --> asm/cpudata.h --> linux/percpu.h -->

    we can't include asm/cpudata.h into asm/topology.h otherwise
    we get:

    include/linux/slub_def.h: In function ‘kmalloc_large’:
    include/linux/slub_def.h:209: error: implicit declaration of function ‘__get_free_pages’
    include/linux/slub_def.h:209: error: ‘__GFP_COMP’ undeclared (first use in this function)
    include/linux/slub_def.h:209: error: (Each undeclared identifier is reported only once
    include/linux/slub_def.h:209: error: for each function it appears in.)
    include/linux/slub_def.h:209: warning: cast to pointer from integer of different size

    for the drivers/base/topology.o build failure case above.

    Actually, looking at the patch, where is the part from Alexey
    that does the "fix sparc64"? I see nothing in the patch that
    would even appear to possibly be for that. The diffstat is:

    arch/avr32/kernel/traps.c | 1 +
    arch/sh/kernel/traps_32.c | 1 +
    drivers/acpi/processor_idle.c | 1 +
    include/asm-generic/local.h | 1 -
    4 files changed, 3 insertions(+), 1 deletion(-)

    Was Alexey's fix removed or lost? :-/
