• 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.
