  • 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.

  • b149ee223   [PATCH] NTP: ntp-helper functions ... Browse Code »

    This patch cleans up a commonly repeated set of changes to the NTP state
    variables by adding two helper inline functions:

    ntp_clear(): Clears the ntp state variables

    ntp_synced(): Returns 1 if the system is synced with a time server.

    This was compile tested for alpha, arm, i386, x86-64, ppc64, s390, sparc,
    sparc64.

  • 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.

  • 59586e5a2   [PATCH] Don't export machine_restart, machine_halt, or machine_power_off. ... Browse Code »

    machine_restart, machine_halt and machine_power_off are machine
    specific hooks deep into the reboot logic, that modules
    have no business messing with. Usually code should be calling
    kernel_restart, kernel_halt, kernel_power_off, or
    emergency_restart. So don't export machine_restart,
    machine_halt, and machine_power_off so we can catch buggy users.

  • 1da177e4c   Linux-2.6.12-rc2 ... Browse Code »

    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!
