linux-next: build warning after merge of the tip and rcu trees

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

kernel/debug/kdb/kdb_support.c: In function 'kdb_task_state_char':
kernel/debug/kdb/kdb_support.c:639:2: warning: passing argument 1 of 'is_idle_task' discards 'const' qualifier from pointer target type [enabled by default]
include/linux/sched.h:2097:20: note: expected 'struct task_struct *' but argument is of type 'const struct task_struct *'

Introduced by commit 7fc20c5cbdd1 ("kdb: Make KDB use the new
is_idle_task() API").

This begs the question: Why does is_idle_task() not take a "const struct task_struct *"?
