  • 53b8a315b   [PATCH] Convert highest_possible_processor_id to nr_cpu_ids ... Browse Code »

    We frequently need the maximum number of possible processors in order to
    allocate arrays for all processors. So far this was done using
    highest_possible_processor_id(). However, we do need the number of
    processors not the highest id. Moreover the number was so far dynamically
    calculated on each invokation. The number of possible processors does not
    change when the system is running. We can therefore calculate that number
    once.

  • 6220ec784   [PATCH] highest_possible_node_id() linkage fix ... Browse Code »

    Qooting Adrian:

    - net/sunrpc/svc.c uses highest_possible_node_id()

    - include/linux/nodemask.h says highest_possible_node_id() is
    out-of-line #if MAX_NUMNODES > 1

    - the out-of-line highest_possible_node_id() is in lib/cpumask.c

    - lib/Makefile: lib-$(CONFIG_SMP) += cpumask.o
    CONFIG_ARCH_DISCONTIGMEM_ENABLE=y, CONFIG_SMP=n, CONFIG_SUNRPC=y

    -> highest_possible_node_id() is used in net/sunrpc/svc.c
    CONFIG_NODES_SHIFT defined and > 0

    -> include/linux/numa.h: MAX_NUMNODES > 1

    -> compile error

    The bug is not present on architectures where ARCH_DISCONTIGMEM_ENABLE
    depends on NUMA (but m32r isn't the only affected architecture).

    So move the function into page_alloc.c

    Also, optimise any_online_cpu() out of existence on CONFIG_SMP=n.

    This function seems inefficient. Can't we simply AND the two masks, then use
    find_first_bit()?

    Shrinks the only caller (net/bridge/netfilter/ebtables.c) by 174 bytes.

    Also, optimise highest_possible_processor_id() out of existence on
    CONFIG_SMP=n.
