      cpumask: convert drivers/net/sfc · 2f8975fb
      Rusty Russell 提交于
      Impact: reduce stack usage, use new cpumask API.
      
      Remove a cpumask from the stack.  Ben Hutchings indicated that printing
      a warning and returning 1 was acceptable for the corner case where allocation
      fails.

      cpumask: Use topology_core_cpumask()/topology_thread_cpumask() · fbd59a8d
      Rusty Russell 提交于
      Impact: reduce stack usage, use new cpumask API.
      
      This actually uses topology_core_cpumask() and
      topology_thread_cpumask(), removing the only users of
      topology_core_siblings() and topology_thread_siblings()

      cpumask: update irq_desc to use cpumask_var_t · 7f7ace0c
      Mike Travis 提交于
      Impact: reduce memory usage, use new cpumask API.
      
      Replace the affinity and pending_masks with cpumask_var_t's.  This adds
      to the significant size reduction done with the SPARSE_IRQS changes.
      
      The added functions (init_alloc_desc_masks & init_copy_desc_masks) are
      in the include file so they can be inlined (and optimized out for the
      !CONFIG_CPUMASKS_OFFSTACK case.)  [Naming chosen to be consistent with
      the other init*irq functions, as well as the backwards arg declaration
      of "from, to" instead of the more common "to, from" standard.]
      
      Includes a slight change to the declaration of struct irq_desc to embed
      the pending_mask within ifdef(CONFIG_SMP) to be consistent with other
      references, and some small changes to Xen.
      
      Tested: sparse/non-sparse/cpumask_offstack/non-cpumask_offstack/nonuma/nosmp on x86_64
