  • 4a4741577   Kconfig: update flightly outdated CONFIG_SMP documentation ... Browse Code »

    Remove an outdated reference to "most personal computers" having only one
    CPU, and change the use of "singleprocessor" and "single processor" in
    CONFIG_SMP's documentation to "uniprocessor" across all arches where that
    documentation is present.

  • d1a1dc0be   consolidate per-arch stack overflow debugging options ... Browse Code »

    Original posting:

    http://lkml.kernel.org/r/20121214184202.F54094D9@kernel.stglabs.ibm.com

    Several architectures have similar stack debugging config options.
    They all pretty much do the same thing, some with slightly
    differing help text.

    This patch changes the architectures to instead enable a Kconfig
    boolean, and then use that boolean in the generic Kconfig.debug
    to present the actual menu option. This removes a bunch of
    duplication and adds consistency across arches.

    In commit 887cbce0adea ("arch Kconfig: centralise ARCH_NO_VIRT_TO_BUS")
    I introduced the config sybmol HAVE_VIRT_TO_BUS and selected that where
    needed. I am not sure what I was thinking. Instead, just directly
    select VIRT_TO_BUS where it is needed.

    All architectures have

    None of them have __ARCH_WANT_KERNEL_EXECVE and there are only two callers
    of kernel_execve() (which is a trivial wrapper for do_execve() now) left.
    Kill the conditionals and make both callers use do_execve().

  • 786d35d45   Make most arch asm/module.h files use asm-generic/module.h ... Browse Code »

    Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
    ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
    into asm-generic/module.h for all arches bar MIPS.

    Also, use the generic definition mod_arch_specific where possible.

    To this end, I've defined three new config bools:

    (*) HAVE_MOD_ARCH_SPECIFIC

    Arches define this if they don't want to use the empty generic
    mod_arch_specific struct.

    (*) MODULES_USE_ELF_RELA

    Arches define this if their modules can contain RELA records. This causes
    the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
    defined by the arch rather than have the core emit an error message.

    (*) MODULES_USE_ELF_REL

    Arches define this if their modules can contain REL records. This causes
    the Elf_Rel mapping to be emitted and allows apply_relocate() to be
    defined by the arch rather than have the core emit an error message.

    Note that it is possible to allow both REL and RELA records: m68k and mips are
    two arches that do this.

    With this, some arch asm/module.h files can be deleted entirely and replaced
    with a generic-y marker in the arch Kbuild file.

    Additionally, I have removed the bits from m32r and score that handle the
    unsupported type of relocation record as that's now handled centrally.

    Rather than #define the options manually in the architecture code, add
    Kconfig options for them and select them there instead. This also allows
    us to select the compat IPC version parsing automatically for platforms

  • 764e0da14   timers: Fixup the Kconfig consolidation fallout ... Browse Code »

    Sigh, I missed to check which architecture Kconfig files actually
    include the core Kconfig file. There are a few which did not. So we
    broke them.

    Instead of adding the includes to those, we are better off to move the
    include to init/Kconfig like we did already with irqs and others.

    This does not change anything for the architectures using the old
    style periodic timer mode. It just solves the build wreckage there.

    For those architectures which use the clock events infrastructure it
    moves the include of the core Kconfig file to "General setup" which is
    a way more logical place than having it at random locations specified
    by the architecture specific Kconfigs.

    The pci_iomap variant that arch/mn10300/unit-asb2305/pci-iomap.c
    uses differs from the generic one in that it does
    not use ioremap_nocache for PCI addresses.
    However, it turns out that PCI addresses are
    automatically noncached, so switching to ioremap_nocache
    and to the generic implementation is safe.

    Awhile back I removed all the CONFIG_GENERIC_TIME referecnes as
    the last of the non-GENERIC_TIME arches were converted.

    However, due to the functionality being important and around for
    awhile, there apparently were some out of tree hardware enablement
    patches that used it and have since been merged.

    This patch removes the remaining instances of GENERIC_TIME.

  • 351f8f8e6   kernel: clean up USE_GENERIC_SMP_HELPERS ... Browse Code »

    For arch which needs USE_GENERIC_SMP_HELPERS, it has to select
    USE_GENERIC_SMP_HELPERS, rather than leaving a choice to user, since they
    don't provide their own implementions.

    Also, move on_each_cpu() to kernel/smp.c, it is strange to put it in
    kernel/softirq.c.

    For arch which doesn't use USE_GENERIC_SMP_HELPERS, e.g. blackfin, only
    on_each_cpu() is compiled.
