Hi Thomas,

FYI, there are new sparse warnings show up in

tree:   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git auto-latest

commit: 3e339b5dae24a7065e196eb8d0145ab2f8cc2d2d [25/37] softirq: Use hotplug thread infrastructure

All sparse warnings:

  kernel/softirq.c:408:8: sparse: symbol 'tasklet_vec' was not declared. Should it be static?
  kernel/softirq.c:409:8: sparse: symbol 'tasklet_hi_vec' was not declared. Should it be static?
+ kernel/softirq.c:843:36: sparse: incorrect type in initializer (different address spaces)
  kernel/softirq.c:843:36:    expected struct task_struct [noderef] <asn:3>**store
  kernel/softirq.c:843:36:    got struct task_struct *[noderef] [toplevel] <asn:3>*<noident>

vim +843 kernel/softirq.c
