Subjectlinux-next: build failure after merge of the final tree
Hi all,

After merging the final tree, today's linux-next build (sparc defconfig)
failed like this:

arch/sparc/kernel/kgdb_32.c: In function 'sleeping_thread_to_gdb_regs':
arch/sparc/kernel/kgdb_32.c:46:9: error: implicit declaration of function 'task_thread_info' [-Werror=implicit-function-declaration]
arch/sparc/kernel/kgdb_32.c:46:26: error: initialization makes pointer from integer without a cast [-Werror]

I can only imagine that the implicit include of linux/sched.h got removed
in one of our include file changes. :-(

I have added this patch for today:
