  • 5e5419734   add mm argument to pte/pmd/pud/pgd_free ... Browse Code »

    (with Martin Schwidefsky )

    The pgd/pud/pmd/pte page table allocation functions get a mm_struct pointer as
    first argument. The free functions do not get the mm_struct argument. This
    is 1) asymmetrical and 2) to do mm related page table allocations the mm
    argument is needed on the free function as well.

    The I-cache disable is an errata workaround, so the solution is to
    disable FIQs across the section with the I-cache disabled.

  • 19c5870c0   Use helpers to obtain task pid in printks (arch code) ... Browse Code »

    One of the easiest things to isolate is the pid printed in kernel log.
    There was a patch, that made this for arch-independent code, this one makes
    so for arch/xxx files.

    It took some time to cross-compile it, but hopefully these are all the
    printks in arch code.

  • b460cbc58   pid namespaces: define is_global_init() and is_container_init() ... Browse Code »

    is_init() is an ambiguous name for the pid==1 check. Split it into
    is_global_init() and is_container_init().

    A cgroup init has it's tsk->pid == 1.

    A global init also has it's tsk->pid == 1 and it's active pid namespace
    is the init_pid_ns. But rather than check the active pid namespace,
    compare the task structure with 'init_pid_ns.child_reaper', which is
    initialized during boot to the /sbin/init process and never changes.

    Changelog:

    2.6.22-rc4-mm2-pidns1:
    - Use 'init_pid_ns.child_reaper' to determine if a given task is the
    global init (/sbin/init) process. This would improve performance
    and remove dependence on the task_pid().

    2.6.21-mm2-pidns2:

    - [Sukadev Bhattiprolu] Changed is_container_init() calls in {powerpc,
    ppc,avr32}/traps.c for the _exception() call to is_global_init().
    This way, we kill only the cgroup if the cgroup's init has a
    bug rather than force a kernel panic.

  • dcca2bde4   During VM oom condition, kill all threads in process group ... Browse Code »

    We have had complaints where a threaded application is left in a bad state
    after one of it's threads is killed when we hit a VM: out_of_memory
    condition.

    Killing just one of the process threads can leave the application in a bad
    state, whereas killing the entire process group would allow for the
    application to restart, or be otherwise handled, and makes it very obvious
    that something has gone wrong.

    This change allows the entire process group to be taken down, rather
    than just the one thread.

    The bare-bones MX31 support in this patch

    It assumes that Redboot is the boot loader.

    however that would be for another patch).

  • 7b9c7b4d0   [ARM] Fix non-page aligned boot time mappings ... Browse Code »

    AT91SAM9260 stopped booting with the recent changes to MM
    initialisation - it was asking for a non-aligned virtual address
    which caused loops to be non-terminal. Fix this by rounding
    virtual addresses down, but remember to include the offset in
    the length, and round the length up to the following page.

    This means that asking for a mapping of 4K starting at 2K into
    a page maps two pages as one would expect.

  • e8edc6e03   Detach sched.h from mm.h ... Browse Code »

    First thing mm.h does is including sched.h solely for can_do_mlock() inline
    function which has "current" dereference inside. By dealing with can_do_mlock()
    mm.h can be detached from sched.h which is good. See below, why.

    This patch
    a) removes unconditional inclusion of sched.h from mm.h
    b) makes can_do_mlock() normal function in mm/mlock.c
    c) exports can_do_mlock() to not break compilation
    d) adds sched.h inclusions back to files that were getting it indirectly.
    e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
    getting them indirectly

    Net result is:
    a) mm.h users would get less code to open, read, preprocess, parse, ... if
    they don't need sched.h
    b) sched.h stops being dependency for significant number of files:
    on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
    after patch it's only 3744 (-8.3%).

  • 516793c61   [ARM] ARMv6: add CPU_HAS_ASID configuration ... Browse Code »

    Presently, we check for the minimum ARM architecture that we're
    building for to determine whether we need ASID support. This is
    wrong - if we're going to support a range of CPUs which include
    ARMv6 or higher, we need the ASID.

    Convert the checks to use a new configuration symbol, and arrange
    for ARMv6 and higher CPU entries to select it.

  • c53c9cf60   [ARM] 4331/3: Support for Micrel/Kendin KS8695 processor ... Browse Code »

    Add core support for the Kendin/Micrel KS8695 processor family.

    It is an ARM922-T based SoC with integrated USART, 4-port Ethernet
    Switch, WAN Ethernet port, and optional PCI Host bridge, etc.
    http://www.micrel.com/page.do?page=product-info/sys_on_chip.jsp

    This patch is based on earlier patches from Lennert Buytenhek, Ben
    Dooks and Greg Ungerer posted to the arm-linux-kernel mailing list in
    March 2006; and Micrel's 2.6.9 port.
