  • de03c72cf   mm: convert mm->cpu_vm_cpumask into cpumask_var_t ... Browse Code »

    cpumask_t is very big struct and cpu_vm_mask is placed wrong position.
    It might lead to reduce cache hit ratio.

    This patch has two change.
    1) Move the place of cpumask into last of mm_struct. Because usually cpumask
    is accessed only front bits when the system has cpu-hotplug capability
    2) Convert cpu_vm_mask into cpumask_var_t. It may help to reduce memory
    footprint if cpumask_size() will use nr_cpumask_bits properly in future.

    In addition, this patch change the name of cpu_vm_mask with cpu_vm_mask_var.
    It may help to detect out of tree cpu_vm_mask users.

    This patch has no functional change.

  • a1b200e27   mm: provide init_mm mm_context initializer ... Browse Code »

    Provide an INIT_MM_CONTEXT intializer macro which can be used to
    statically initialize mm_struct:mm_context of init_mm. This way we can
    get rid of code which will do the initialization at run time (on s390).

    In addition the current code can be found at a place where it is not
    expected. So let's have a common initializer which architectures
    can use if needed.

    This is based on a patch from Suzuki Poulose.

  • bb1f17b03   mm: consolidate init_mm definition ... Browse Code »

    * create mm/init-mm.c, move init_mm there
    * remove INIT_MM, initialize init_mm with C99 initializer
    * unexport init_mm on all arches:

    init_mm is already unexported on x86.

    One strange place is some OMAP driver (drivers/video/omap/) which
    won't build modular, but it's already wants get_vm_area() export.
    Somebody should look there.
