  1. [PATCH] (updated, rolled up) make section names compatible with -ffunction-sections -fdata-sections

    Hi Andrew,

    Here is the update against current Linus tree,
    rolled up into one patch.

    James Bottomley suggested a different naming scheme:
    instead of swapping parts (.text.head -> .head.text),
    prepend .kernel to our special section names.
    This patch implements his idea.

    ppc and v850 are dropped per comments from arch people.
    parisc and x86 had minor fixes. x86 fix added proper
    executable bits to a section:

    -.section ".text.head"
    +.section ".kernel.text.head","ax",@progbits

    Does arch/m68k/kernel/sun3-head.S need the same fix?

    The patch is run-tested on x86_64.

    I would like to ask arch maintainers to ACK/NAK this patch,
    and Andrew to act accordingly.

    Changelog follows:



    The purpose of these patches is to make kernel buildable
    with "gcc -ffunction-sections -fdata-sections".

    The problem is that with -ffunction-sections -fdata-sections gcc
    creates sections like .text.head and .data.nosave
    whenever someone has innocuous code like this:

    static void head(...) {...}

    or this:

    int f(...) { static int nosave; ... }

    somewhere in the kernel.

    Kernel linker script is confused by such names and puts these sections
    in wrong places.

    This patch renames all "magic" section names used by kernel
    to not have this format, eliminating the possibility of such collisions.

    the Blackfin piece is just one line and shouldnt be a problem from our
    side. thanks.

    btw, arch maintainers have an alias "linux-arch@vger.kernel.org" ...
    but it doesnt appear to be in MAINTAINERS ?

    Why not '.linux'?

    Is this patch intended to go to Linus for 2.6.27?

    Acked-by: Ingo Molnar

    could you please put the ax/progbits fix in front of the queue so that
    it becomes bisectable and so that the later patches keep their "it
    should not change anything" property?

    I.e. do not mix small fixlets into a large set of "no change" patches -
    split them out in front. This is really important for the x86 bits as
    linker script changes tend to be quite fragile.
