  • The warning issued by fs/binfmt_flat.c when the format handler is given a
    non-FLAT and non-script executable is annoying to say the least when working
    with FDPIC ELF objects. If you build a kernel that supports both FLAT and
    FDPIC ELFs on no-mmu, every time you execute an FDPIC ELF, the kernel spits
    out this message. While I understand a lot of newcomers to the no-mmu world
    screw up generation of FLAT binaries, this warning is not usable for systems
    that support more than just FLAT.

    /home/bunk/linux/kernel-2.6/git/linux-2.6/arch/cris/arch-v10/lib/memset.c:192: error: lvalue required as increment operand
    ... etc ...

    This is due to the use of the construct:

    *((long*)dst)++ = lc;

    Which is no longer legal since casts don't return an lvalue.

    The solution is to import the implementation from newlib,
    which is continually autotested together with GCC mainline,
    and uses the construct:

    *(long *) dst = lc; dst += 4;

    With this change, the generated code actually shrinks 76 bytes
    since gcc notices that it can use autoincrement for the move
    instruction in CRIS.

    text data bss dec hex filename
    304 0 0 304 130 memset.old.o
    text data bss dec hex filename
    228 0 0 228 e4 memset.o

    Since this is an import of a file from newlib, I'm not touching
    the formatting or correcting any checkpatch errors.

    Note also that even if the two files for the CRIS v10 and CRIS v32
    are identical at the moment, it might be possible to tweak the
    CRIS v32 version. Thus, I'm not yet folding them into the same file,
    at least not until we've done some research on it.

  • This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous
    to the Module.symvers file, the build will now write a Module.markers file
    when CONFIG_MARKERS=y is set. This file lists the name, defining module, and
    format string of each marker, separated by \t characters. This simple text
    file can be used by offline build procedures for instrumentation code,
    analogous to how System.map and Module.symvers can be useful to have for
    kernels other than the one you are running right now.

    The strings are made easy to extract by having the __trace_mark macro define
    the name and format together in a single array called __mstrtab_* in the
    __markers_strings section. This is straightforward and reliable as long as
    the marker structs are always defined by this macro. It is an unreasonable
    amount of hairy work to extract the string pointers from the __markers section
    structs, which entails handling a relocation type for every machine under the
    sun.

  • RCU style multiple probes support for the Linux Kernel Markers. Common case
    (one probe) is still fast and does not require dynamic allocation or a
    supplementary pointer dereference on the fast path.

    - Move preempt disable from the marker site to the callback.

    Since we now have an internal callback, move the preempt disable/enable to the
    callback instead of the marker site.

    Since the callback change is done asynchronously (passing from a handler that
    supports arguments to a handler that does not setup the arguments is no
    arguments are passed), we can safely update it even if it is outside the
    preempt disable section.

    - Move probe arm to probe connection. Now, a connected probe is automatically
    armed.

    Remove MARK_MAX_FORMAT_LEN, unused.

    This patch modifies the Linux Kernel Markers API : it removes the probe
    "arm/disarm" and changes the probe function prototype : it now expects a
    va_list * instead of a "...".

    If we want to have more than one probe connected to a marker at a given
    time (LTTng, or blktrace, ssytemtap) then we need this patch. Without it,
    connecting a second probe handler to a marker will fail.

    It allow us, for instance, to do interesting combinations :

    Do standard tracing with LTTng and, eventually, to compute statistics
    with SystemTAP, or to have a special trigger on an event that would call
    a systemtap script which would stop flight recorder tracing.

  • ipwireless (added by 099dc4fb62653f6019d78db55fba7a18ef02d65b) is clearly

    /home/pmundt/devel/git/sh-2.6.25/drivers/net/ppp_generic.c:2517: undefined reference to `free_netdev'
    [ ... and many more ... ]

    select strikes again. ipwireless selects PPP which in turn tries to select
    SLHC, both of which are technically "protected" by an if NETDEVICES
    in drivers/net/Kconfig. This leads to .config hilarity, with net suddenly
    ending up in the SCSI menu:

    #
    # SCSI device support
    #
    # CONFIG_SCSI_DMA is not set
    # CONFIG_SCSI_NETLINK is not set
    CONFIG_PPP=y
    # CONFIG_PHONE is not set

    Curiously the SLHC select from PPP doesn't seem to happen, as there's no
    CONFIG_SLHC=y (only CONFIG_PPP=y gets set) -- Kconfig bug? Caught with a
    randconfig.

  • On alpha, ia64 and ppc64 only relocations to local data can go into
    read-only sections. The vast majority of module parameters use the global
    generic param_set_*/param_get_* functions, so the 'const' attribute for
    struct kernel_param is not only useless, but it also causes compile
    failures due to 'section type conflict' in those rare cases where
    param_set/get are local functions.

  • Commit d3d74453c34f8fd87674a8cf5b8a327c68f22e99 ("hrtimer: fixup the
    HRTIMER_CB_IRQSAFE_NO_SOFTIRQ fallback") broke several archs, and since
    only Russell bothered to merge the fix, and Greg to ACK his arch, I'm
    sending this for merger.

    I have confirmation that the Alpha bit results in a booting kernel.
    That leaves: blackfin, frv, sh and sparc untested.

    The deadlock in question was found by Russell:

    IRQ handle
    -> timer_tick() - xtime seqlock held for write
    -> update_process_times()
    -> run_local_timers()
    -> hrtimer_run_queues()
    -> hrtimer_get_softirq_time() - tries to get a read lock

    Now, Thomas assures me the fix is trivial, only do_timer() needs to be
    done under the xtime_lock, and update_process_times() can savely be
    removed from under it.

    unconditionally fills in a 32-bit integer return value regardless of the

    So claiming to take a "void *" is wrong, as is passing in a pointer to
    just a byte variable.
