      cpumask: convert struct clock_event_device to cpumask pointers. · 320ab2b0
      Rusty Russell authored
      Impact: change calling convention of existing clock_event APIs
      
      struct clock_event_timer's cpumask field gets changed to take pointer,
      as does the ->broadcast function.
      
      Another single-patch change.  For safety, we BUG_ON() in
      clockevents_register_device() if it's not set.

      cpumask: make irq_set_affinity() take a const struct cpumask · 0de26520
      Rusty Russell authored
      Impact: change existing irq_chip API
      
      Not much point with gentle transition here: the struct irq_chip's
      setaffinity method signature needs to change.
      
      Fortunately, not widely used code, but hits a few architectures.
      
      Note: In irq_select_affinity() I save a temporary in by mangling
      irq_desc[irq].affinity directly.  Ingo, does this break anything?

      cpumask: change cpumask_scnprintf, cpumask_parse_user, cpulist_parse, and... · 29c0177e

      cpumask: change cpumask_scnprintf, cpumask_parse_user, cpulist_parse, and cpulist_scnprintf to take pointers.
      
      Impact: change calling convention of existing cpumask APIs
      
      Most cpumask functions started with cpus_: these have been replaced by
      cpumask_ ones which take struct cpumask pointers as expected.
      
      These four functions don't have good replacement names; fortunately
      they're rarely used, so we just change them over.

      cpumask: centralize cpu_online_map and cpu_possible_map · 98a79d6a
      Rusty Russell authored
      Impact: cleanup
      
      Each SMP arch defines these themselves.  Move them to a central
      location.
      
      Twists:
      1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a
         CONFIG_INIT_ALL_POSSIBLE for this rather than break them.
      
      2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
         Those archs simply have phys_cpu_present_map replaced everywhere.
      
      3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky
         so I just manipulate them both in sync.
      
      4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map'
         declarations.
