  • Add missing #inclusions of to a whole bunch of files that should
    really include it. Note that this can replace #inclusions of .

    This is required for the patch to sort out irqflags handling function naming to
    compile on MIPS.

    The problem is that these files require access to things like setup_irq() -
    which isn't available by #including

  • Separate USB code into a file separate from asic/asic_devices.

    Separating the USB code from everything else in asic/asic_devices.c goes
    a long way toward reducing the use of that file as a dumping ground for
    everything that didn't seem to fit anywhere else.

  • Additional changes to Youichi Yuasa's command line simplication code

    The PowerTV platform uses a non-standard way to get the kernel command
    line--we insert a built-in command line into arcs_cmdline and to
    get additional command line information from the bootloader via a
    pointer in the a1 register. It is necessary to insert a space between
    to the two strings or the last argument from arcs_cmdline and the first
    argument from the bootloader may be inadvertantly combined.

    It is also necessary to set CONFIG_CMDLINE_BOOL to "y" and to set the
    default command line to an empty string to get the simplified code to
    work properly in the PowerTV environment.

  • Replace phys_to_dma()/dma_to_phys() looping algorithm with an O(1) algorithm
    The approach taken is inspired by the sparse memory implementation: take a
    certain number of high-order bits off the address them, use this as an
    index into a table containing an offset to the desired address and add
    it to the original value. There is a table for mapping physical addresses
    to DMA addresses and another one for the reverse mapping. The table sizes
    depend on how fine-grained the mappings need to be; Coarser granularity
    less to smaller tables. On a processor with 32-bit physical and DMA
    addresses, with 4 MIB granularity, memory usage is two 2048-byte arrays.
    Each 32-byte cache line thus covers 64 MiB of address space.

    Also, renames phys_to_bus() to phys_to_dma() and bus_to_phys() to
    dma_to_phys() to align with kernel usage.

    [Ralf: Fixed silly build breakage due to stackoverflow warning caused by
    huge array on stack.]

  • Modifications to the boot memory allocation structures to make them easier
    to read and maintain. Note that this will not pass checkpatch because
    it wants a structure element initializer to be enclosed in a
    do {...} while(...), which is obvious nonsensical.

  • …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.

  • Pre-compute addresses for the basic ASIC registers. This speeds up access
    and allows memory for unused configurations to be freed. In addition,
    uninitialized register addresses will be returned as NULL to catch bad
    usage quickly.

  • Add the Cisco Powertv cable settop box to the MIPS tree. This platform is
    based on a MIPS 24Kc processor with various devices integrated on the same
    ASIC. There are multiple models of this box, with differing configuration
    but the same kernel runs across the product line.
