  • 2308acca6   [PATCH] "tiny-make-id16-support-optional" fixes ... Browse Code »

    It seems the "make UID16 support optional" patch was checked when it
    edited the -tiny tree some time ago, but it wasn't checked whether it
    still matches the current situation when it was submitted for inclusion
    in -mm. This patch fixes the following bugs:
    - ARCH_S390X does no longer exist, nowadays this has to be expressed
    through (S390 && 64BIT)
    - in five architecture specific Kconfig files the UID16 options
    weren't removed

    Additionally, it changes the fragile negative dependencies of UID16 to
    positive dependencies (new architectures are more likely to not require
    UID16 support).

  • 5bfb5d690   [PATCH] sched: disable preempt in idle tasks ... Browse Code »

    Run idle threads with preempt disabled.

    Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()).
    How did it ever work before?

    Might fix the CPU hotplugging hang which Nigel Cunningham noted.

    We think the bug hits if the idle thread is preempted after checking
    need_resched() and before going to sleep, then the CPU offlined.

    After calling stop_machine_run, the CPU eventually returns from preemption and
    into the idle thread and goes to sleep. The CPU will continue executing
    previous idle and have no chance to call play_dead.

    By disabling preemption until we are ready to explicitly schedule, this bug is
    fixed and the idle threads generally become more robust.

  • 481bed454   [PATCH] consolidate sys_ptrace() ... Browse Code »

    The sys_ptrace boilerplate code (everything outside the big switch
    statement for the arch-specific requests) is shared by most architectures.
    This patch moves it to kernel/ptrace.c and leaves the arch-specific code as
    arch_ptrace.

    Some architectures have a too different ptrace so we have to exclude them.
    They continue to keep their implementations. For sh64 I had to add a
    sh64_ptrace wrapper because it does some initialization on the first call.
    For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but
    SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

    Manual #include fixups for clashes - there may be some unnecessary

  • 4e57b6817   [PATCH] fix missing includes ... Browse Code »

    I recently picked up my older work to remove unnecessary #includes of
    sched.h, starting from a patch by Dave Jones to not include sched.h
    from module.h. This reduces the number of indirect includes of sched.h
    by ~300. Another ~400 pointless direct includes can be removed after
    this disentangling (patch to follow later).
    However, quite a few indirect includes need to be fixed up for this.

    In order to feed the patches through -mm with as little disturbance as
    possible, I've split out the fixes I accumulated up to now (complete for
    i386 and x86_64, more archs to follow later) and post them before the real
    patch. This way this large part of the patch is kept simple with only
    adding #includes, and all hunks are independent of each other. So if any
    hunk rejects or gets in the way of other patches, just drop it. My scripts
    will pick it up again in the next round.

  • 4db2ce019   [LIB]: Consolidate _atomic_dec_and_lock() ... Browse Code »

    Several implementations were essentialy a common piece of C code using
    the cmpxchg() macro. Put the implementation in one spot that everyone
    can share, and convert sparc64 over to using this.

    Alpha is the lone arch-specific implementation, which codes up a
    special fast path for the common case in order to avoid GP reloading
    which a pure C version would require.

  • 5bb782690   kbuild: rename prepare to archprepare to fix dependency chain ... Browse Code »

    When introducing the generic asm-offsets.h support the dependency
    chain for the prepare targets was changed. All build scripts expecting
    include/asm/asm-offsets.h to be made when using the prepare target would broke.
    With the limited number of prepare targets left in arch Makefiles
    the trivial solution was to introduce a new arch specific target: archprepare

    The dependency chain looks like this now:

    prepare
    |
    +--> prepare0
    |
    +--> archprepare
    |
    +--> scripts_basic
    +--> prepare1
    |
    +---> prepare2
    |
    +--> prepare3

    So prepare 3 is processed before prepare2 etc.
    This guaantees that the asm symlink, version.h, scripts_basic
    are all updated before archprepare is processed.

    prepare0 which build the asm-offsets.h file will need the
    actions performed by archprepare.

    The head target is now named prepare, because users scripts will most
    likely use that target, but prepare-all has been kept for compatibility.
    Updated Documentation/kbuild/makefiles.txt.

    This was compile tested for alpha, arm, i386, x86-64, ppc64, s390, sparc,

  • 69be8f189   [PATCH] convert signal handling of NODEFER to act like other Unix boxes. ... Browse Code »

    It has been reported that the way Linux handles NODEFER for signals is
    not consistent with the way other Unix boxes handle it. I've written a
    program to test the behavior of how this flag affects signals and had
    several reports from people who ran this on various Unix boxes,
    confirming that Linux seems to be unique on the way this is handled.

    The way NODEFER affects signals on other Unix boxes is as follows:

    1) If NODEFER is set, other signals in sa_mask are still blocked.

    2) If NODEFER is set and the signal is in sa_mask, then the signal is
    still blocked. (Note: this is the behavior of all tested but Linux _and_
    NetBSD 2.0 *).

    The way NODEFER affects signals on Linux:

    1) If NODEFER is set, other signals are _not_ blocked regardless of
    sa_mask (Even NetBSD doesn't do this).

    2) If NODEFER is set and the signal is in sa_mask, then the signal being
    handled is not blocked.

    The patch converts signal handling in all current Linux architectures to
    the way most Unix boxes work.

    Unix boxes that were tested: DU4, AIX 5.2, Irix 6.5, NetBSD 2.0, SFU
    3.5 on WinXP, AIX 5.3, Mac OSX, and of course Linux 2.6.13-rcX.

    * NetBSD was the only other Unix to behave like Linux on point #2. The
    main concern was brought up by point #1 which even NetBSD isn't like
    Linux. So with this patch, we leave NetBSD as the lonely one that
    behaves differently here with #2.

  • d5950b435   [NET]: add a top-level Networking menu to *config ... Browse Code »

    Create a new top-level menu named "Networking" thus moving
    net related options and protocol selection way from the drivers
    menu and up on the top-level where they belong.

    To implement this all architectures has to source "net/Kconfig" before
    drivers/*/Kconfig in their Kconfig file. This change has been
    implemented for all architectures.

    Device drivers for ordinary NIC's are still to be found
    in the Device Drivers section, but Bluetooth, IrDA and ax25
    are located with their corresponding menu entries under the new
    networking menu item.

    Now that sys_ipc has been removed from xtensa, asm/ipc.h is no longer

    file is included only from arch code and this patch also removes the only

  • 875914511   [PATCH] xtensa: remove old syscalls ... Browse Code »

    xtensa is now in -rc1, with the obsolete syscalls still in there, so I
    guess this about the last chance to correct the ABI. Applying the patch
    obviously breaks all sorts of user space binaries and probably also
    requires the appropriate changes to be made to libc.

    On the other hand, if a decision is made to keep the broken interface, it
    should at least be a conscious one instead of an oversight.
