Here are the new sha1's: 96f874e: sched: convert remaining old-style cpumask operators 0e3900e: sched: convert local_cpu_mask to cpumask_var_t. 24600ce: sched: convert check_preempt_equal_prio to cpumask_var_t. 68e7456: sched: convert struct cpupri_vec cpumask_var_t. 4212823: sched: convert falback_doms to cpumask_var_t. dcc30a3: sched: convert cpu_isolated_map to cpumask_var_t. d5dd3db: sched: convert sched_domain_debug to cpumask_var_t. 5a16f3d: sched: convert struct (sys_)sched_setaffinity() to cpumask_var_t. e76bd8d: sched: avoid stack var in move_task_off_dead_cpu f17c860: sched: convert sys_sched_getaffinity() to cpumask_var_t. a0e9024: sched: convert rebalance_domains() to cpumask_var_t. 4d2732c: sched: convert idle_balance() to cpumask_var_t. 7d1e6a9: sched: convert nohz struct to cpumask_var_t. c6c4927: sched: convert struct root_domain to cpumask_var_t. 6a7b3dc: sched: convert nohz_cpu_mask to cpumask_var_t. 6c99e9a: sched: convert struct sched_group/sched_domain cpumask_ts to variable bitmaps 758b2cd: sched: wrap sched_group and sched_domain cpumask accesses. 1e5ce4f: sched: remove any_online_cpu() 3404c8d: sched: get rid of boutique sched.c allocations, use cpumask_var_t. abcd083: sched: convert sched.c from for_each_cpu_mask to for_each_cpu. ea6f18e: sched: reduce stack size requirements in kernel/sched.c 943f3d0: Merge branches 'sched/core', 'core/core' and 'tracing/core' into cpus4096 The tip/cpus4096 topic tree is -git based and will be append-only with stable sha1's unless there's some really bad messup forcing a rebase. I've also merged your commits into tip/master and have done cross-arch build testing: testing 9 architectures. testing alpha: -git: pass ( 18), -tip: pass ( 18) testing arm: -git: pass ( 5), -tip: pass ( 5) testing cris: -git: pass ( 28), -tip: pass ( 18) testing i386: -git: pass ( 11), -tip: pass ( 11) testing ia64: -git: pass (132), -tip: pass (135) testing m32r: -git: pass ( 24), -tip: pass ( 24) testing m68k: -git: pass (150), -tip: pass (150) testing mips: -git: pass ( 12), -tip: pass ( 4) testing powerpc: -git: pass ( 12), -tip: pass ( 10) ( The decimal number in paranthesis is the count of build warnings. Twelve other architectures i have crosscompilers for do not currently build fine on -git, with arch defconfigs, using latest gcc 4.3.3. ) Based on these good test results i've also integrated a new cpus4096-next tree and pushed it out for linux-next pickup.
