  • 0b1937ac0   FRV: Fix linkage problems ... Browse Code »

    Make it possible to use __start_notes and __stop_notes without getting a GPREL
    overflow error from the FRV linker.

    Small variables that would otherwise be in .data or .bss may, depending on the
    arch, be placed in special sections (.sdata or .sbss) that permit single
    instruction references on fixed instruction width machines.

    __start_notes and __stop_notes aren't really char variables, and certainly
    don't refer to data in .data or .bss. Making them type "void" fools the
    compiler into not assuming anything about them.

  • da1a679cd   Add /sys/kernel/notes ... Browse Code »

    This patch adds the /sys/kernel/notes magic file. Reading this delivers the
    contents of the kernel's .notes section. This lets userland easily glean any
    detailed information about the running kernel's build that was stored there at
    compile time.

  • c330dda90   [PATCH] Add a sysfs file to determine if a kexec kernel is loaded ... Browse Code »

    Create two files in /sys/kernel, kexec_loaded and kexec_crash_loaded. Each
    file contains a simple boolean value indicating whether the relevant kernel
    has been loaded into memory. The motivation for this is geared around
    support.

  • 51be5606d   [PATCH] kdump: export per cpu crash notes pointer through sysfs ... Browse Code »

    - Kexec on panic functionality allocates memory for saving cpu registers in
    case of system crash event. Address of this allocated memory needs to be
    exported to user space, which is used by kexec-tools.

    - Previously, a single /sys/kernel/crash_notes entry was being exported as
    memory allocated was a single continuous array. Now memory allocation being
    dyanmic and per cpu based, address of per cpu buffer is exported through
    "/sys/devices/system/cpu/cpuX/crash_notes"

    Netlink is unconditionally enabled if CONFIG_NET, so that's OK.

    kobject_uevent.o is compiled even if !CONFIG_HOTPLUG, which is lazy.

    Let's compound the sin.

  • 312c004d3   [PATCH] driver core: replace "hotplug" by "uevent" ... Browse Code »

    Leave the overloaded "hotplug" word to susbsystems which are handling
    real devices. The driver core does not "plug" anything, it just exports
    the state to userspace and generates events.

  • 0f76e5acf   [PATCH] add uevent_helper control in /sys/kernel/ ... Browse Code »

    This deprecates the /proc/sys/kernel/hotplug file, as all
    this stuff should be in /sys some day, right? :)
    In /sys/kernel/ we have now uevent_seqnum and uevent_helper.
    The seqnum is no longer used by udev, as the version for this
    kernel depends on netlink which events will never get
    out-of-order.

    Recent udev versions disable the /sbin/hotplug helper with
    an init script, cause it leads to OOM on big boxes by running
    hundreds of shells in parallel. It should be done now by:
    echo "" > /sys/kernel/uevent_helper

    (Note that "-n" does not work, cause neighter proc nor sysfs
    support truncate().)

    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!
