  • Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
    We run all interrupt handlers with interrupts disabled and we even check
    and yell when an interrupt handler returns with interrupts enabled (see
    commit [b738a50a: genirq: Warn when handler enables interrupts]).

    So now this flag is a NOOP and can be removed.

  • …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.

  • Several static uninitialized variables are used in the scope of __init
    functions but are themselves not marked as __initdata. This patch is to put
    those variables to where they belong and to reduce the memory footprint a
    little bit.

    Also, a couple of lines with spaces instead of tabs were fixed.

  • It's possible that the crime interrupt handler is called without
    pending interrupts (probably a hardware issue). To avoid irritating
    "unexpected irq 71" messages, we now just ignore the spurious crime
    interrupts.

    - set io_map_base
    - only fixup end of iomem resource to avoid failing request_resource
    in serial driver
    - killed useless setting of crime_int bit, which caused wrong interrupts

  • The meth ethernet driver for the SGI IP32 aka O2 is so far still an old
    style driver which does not use the device driver model. This is now
    causing issues with some udev based gadgetry in debian-stable. Fixed by
    converting the meth driver to a platform device.

  • o adds missing ST0_IM masks, which caused the logging of valid interrupts
    as spurious
    o stops pnx8550 to log every interrupt as spurious
    o adds cause register masks for ip22/ip32, which caused handling of masked
    interrupts
    o removes some superfluous parentheses in the SNI interrupt code

  • Many Makefiles in arch/mips have EXTRA_AFLAGS := $(CFLAGS) line. This
    is redundant while AFLAGS contains $(cflags-y) and any options only
    listed in CFLAGS (not in cflags-y) should be unnecessary for asm
    sources.
