  • 9babed6a6   m32r: fix build warning about putc ... Browse Code »

    We were getting build warning:

    arch/m32r/boot/compressed/m32r_sio.c:11:13:
    warning: conflicting types for built-in function 'putc'

    Here putc is used as a static function so lets just rename it to avoid
    the conflict with the builtin putc.

    Since commit 2aedcd098a94 ('kbuild: suppress annoying "... is up to
    date." message'), $(call if_changed,...) is evaluated to "@:"
    when there is nothing to do.

    We no longer need to add "@:" after $(call if_changed,...) to
    suppress "... is up to date." message.

  • caa27b66b   kbuild: use INSTALLKERNEL to select customized installkernel script ... Browse Code »

    Replace the use of CROSS_COMPILE to select a customized
    installkernel script with the possibility to set INSTALLKERNEL
    to select a custom installkernel script when running make:

    make INSTALLKERNEL=arm-installkernel install

    With this patch we are now more consistent across
    different architectures - they did not all support use
    of CROSS_COMPILE.

    The use of CROSS_COMPILE was a hack as this really belongs
    to gcc/binutils and the installkernel script does not change
    just because we change toolchain.

    The use of CROSS_COMPILE caused troubles with an upcoming patch
    that saves CROSS_COMPILE when a kernel is built - it would no
    longer be installable.
    [Thanks to Peter Z. for this hint]

    This patch undos what Ian did in commit:

    0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46
    ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")

    The patch has been lightly tested on x86 only - but all changes
    looks obvious.

  • 9c88b06dc   m32r: build fix for __stringify macro ... Browse Code »

    This patch fixes the following build error of 2.6.30-rc3-git2:

    AS arch/m32r/kernel/head.o
    In file included from /include/linux/init.h:7,
    from /arch/m32r/kernel/head.S:11:
    /include/linux/stringify.h:9: error: syntax error in macro parameter list
    /include/linux/stringify.h:10: error: syntax error in macro parameter list

    This build error was caused at __HEAD macro in arch/m32r/kernel/head.S,
    which uses __stringify() macro.

    Remove -traditional option from EXTRA_AFLAGS for the m32r,
    because the __stringify() macro depends on the gcc's variadic macro
    extension function, due to commit:

    Make __stringify support variable argument macros too

  • 2d6ffcca6   inflate: refactor inflate malloc code ... Browse Code »

    Inflate requires some dynamic memory allocation very early in the boot
    process and this is provided with a set of four functions:
    malloc/free/gzip_mark/gzip_release.

    The old inflate code used a mark/release strategy rather than implement
    free. This new version instead keeps a count on the number of outstanding
    allocations and when it hits zero, it resets the malloc arena.

    This allows removing all the mark and release implementations and unifying
    all the malloc/free implementations.

    The architecture-dependent code must define two addresses:
    - free_mem_ptr, the address of the beginning of the area in which
    allocations should be made
    - free_mem_end_ptr, the address of the end of the area in which
    allocations should be made. If set to 0, then no check is made on
    the number of allocations, it just grows as much as needed

    The architecture-dependent code can also provide an arch_decomp_wdog()
    function call. This function will be called several times during the
    decompression process, and allow to notify the watchdog that the system is
    still running. If an architecture provides such a call, then it must
    define ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls
    arch_decomp_wdog().

    Work initially done by Matt Mackall, updated to a recent version of the
    kernel and improved by me.

    The M32104UT is an eval board based on an uT-Engine specification. This board

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
