    Because slot 1 of one instr bundle crosses border of two consecutive
    8-bytes, kprobe on slot 1 is disabled. This patch enables kprobe on
    slot1, it only replaces higher 8-bytes of the instruction bundle and
    changes the exception code to ignore the low 12 bits of the break
    number (which is across the border in the lower 8-bytes of the bundle).

    For those instructions which must execute regardless qp bits,
    kprobe on slot 1 is still disabled.

    As many of you know that kprobes exist in the main line kernel for various
    architecture including i386, x86_64, ppc64 and sparc64. Attached patches
    following this mail are a port of Kprobes and Jprobes for IA64.

    I have tesed this patches for kprobes and Jprobes and this seems to work fine.
    I have tested this patch by inserting kprobes on various slots and various
    templates including various types of branch instructions.

    I have also tested this patch using the tool
    http://marc.theaimsgroup.com/?l=linux-kernel&m=111657358022586&w=2 and the
    kprobes for IA64 works great.

    Here is list of TODO things and pathes for the same will appear soon.

    1) Support kprobes on "mov r1=ip" type of instruction
    2) Support Kprobes and Jprobes to exist on the same address
    3) Support Return probes
    3) Architecture independent cleanup of kprobes

    This patch adds the kdebug die notification mechanism needed by Kprobes.

    For break instruction on Branch type slot, imm21 is ignored and value
    zero is placed in IIM register, hence we need to handle kprobes
    for switch case zero.

    From: Rusty Lynch

    At the point in traps.c where we recieve a break with a zero value, we can
    not say if the break was a result of a kprobe or some other debug facility.

    This simple patch changes the informational string to a more correct "break
    0" value, and applies to the 2.6.12-rc2-mm2 tree with all the kprobes
    patches that were just recently included for the next mm cut.

    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!
