Firstly, sorry for so late to continue arc. Now I use latest tool-chain
(content gcc-4.8.0) to compile kernel with allmodconfig, and find three
tool chain issues (2 for gcc, 1 for binutils).
And also excuse me, I am still not quite sure where I should sent these
information to, although you have mentioned some valuable information.
I just list the issue details below, if necessary, please provide more
details where these information should be sent to (e.g. bugzilla), and
I will/should follow and work with related tool chain guys. thanks.

when calling panic(), printk(), or memset() with R_ARC_S21W_PCREL, it may be
overflow (I guess it need be R_ARC_S25W_PCREL).
