[1/1] sparc32,leon: add notify_cpu_starting()

From: Yong Zhang <yong.zhang@windriver.com>

Otherwise cpu_active_mask will not set, which lead to other issue.

Hello Yong,
Thank you for the patch, it works. The SMP is fully
functional again for sparc-leon. I just added a "#include<linux/cpu.h>"
to avoid compiler warning.
Please someone in the cc-list, apply.
-- Greetings Konrad
