    This renames pci flags functions and enums in preparation for creating
    generic version in asm-generic/pci-bridge.h. The following search and
    replace is done:

    s/ppc_pci_/pci_/
    s/PPC_PCI_/PCI_/

    Direct accesses to ppc_pci_flag variable are replaced with helper
    functions.

  • 4018294b5   of: Remove duplicate fields from of_platform_driver ... Browse Code »

    .name, .match_table and .owner are duplicated in both of_platform_driver
    and device_driver. This patch is a removes the extra copies from struct
    of_platform_driver and converts all users to the device_driver members.

    This patch is a pretty mechanical change. The usage model doesn't change
    and if any drivers have been missed, or if anything has been fixed up
    incorrectly, then it will fail with a compile time error, and the fixup
    will be trivial. This patch looks big and scary because it touches so
    many files, but it should be pretty safe.

  • 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.

    get_irq_desc() is a powerpc-specific version of irq_to_desc(). That

  • 28794d34e   powerpc/kconfig: Kill PPC_MULTIPLATFORM ... Browse Code »

    CONFIG_PPC_MULTIPLATFORM is a remain of the pre-powerpc days and isn't
    really meaningful anymore. It was basically equivalent to PPC64 || 6xx.

    This removes it along with the following changes:

    - 32-bit platforms that relied on PPC32 && PPC_MULTIPLATFORM now rely
    on 6xx which is what they want anyway.

    - A new symbol, PPC_BOOK3S, is defined that represent compliance with
    the "Server" variant of the architecture. This is set when either 6xx
    or PPC64 is set and open the door for future BOOK3E 64-bit.

    - 64-bit platforms that relied on PPC64 && PPC_MULTIPLATFORM now use
    PPC64 && PPC_BOOK3S

    - A separate and selectable CONFIG_PPC_OF_BOOT_TRAMPOLINE option is now
    used to control the use of prom_init.c

    Currently there are a number of platforms that open code access to
    the ppc_pci_flags global variable. However, that variable is not
    present if CONFIG_PCI is not set, which can lead to a build break.

    This introduces a number of accessor functions that are defined
    to be empty in the case of CONFIG_PCI being disabled. The
    various platform files in the kernel are updated to use these.

    This reverts commit e3621ee633810be1079d0fa65ac2c904f53b73fa.

    Its possible to build the phylib as a module, however this breaks the
    board code because alloc_mdio_bitbang and mdiobus_register are not
    available if we build as a module. These are needed by the board code
    since it implements the low level mdio bitbang ops.

    So we unconditionally select PHYLIB to ensure its built into the kernel
    if we are building in EP8248E support.

    Long term we should look at moving the mdio_ops into its own file so it
    can be built as a module.
