    This reverts commit ad7a953c522ceb496611d127e51e278bfe0ff483.

    And commit: ("allow stripping of generated symbols under CONFIG_KALLSYMS_ALL")
    9bb482476c6c9d1ae033306440c51ceac93ea80c

    These stripping patches has caused a set of issues:

    1) People have reported compatibility issues with binutils due to
    lack of support for `--strip-unneeded-symbols' with objcopy 2.15.92.0.2
    Reported by: Wenji
    2) ccache and distcc no longer works as expeced
    Reported by: Ted, Roland, + others
    3) The installed modules increased a lot in size
    Reported by: Ted, Davej + others

    This patch changes the way __crc_ symbols are being resolved from
    using ld to do so to using the assembler, thus allowing these symbols
    to be marked local (the linker creates then as global ones) and hence
    allow stripping (for modules) or ignoring (for vmlinux) them. While at
    this, also strip other generated symbols during module installation.

    One potentially debatable point is the handling of the flags passeed
    to gcc when translating the intermediate assembly file into an object:
    passing $(c_flags) unchanged doesn't work as gcc passes --gdwarf2 to
    gas whenever is sees any -g* option, even for -g0, and despite the
    fact that the compiler would have already produced all necessary debug
    info in the C->assembly translation phase. I took the approach of just
    filtering out all -g* options, but an alternative to such negative
    filtering might be to have a positive filter which might, in the ideal
    case allow just all the -Wa,* options to pass through.

    reported that he saw a lot of symbols like this:

    0000000000000b24 N DW.aio.h.903a6d92.2
    0000000000000bce N DW.task_io_accounting.h.8d8de327.0
    0000000000000bec N DW.hrtimer.h.c23659c6.0

    in his System.map / kallsyms output.

    Simple solution is to skip all debugging
    symbols (they are marked 'N').

    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!
