I tested on latest kernel today one more time, there is no error and warning on my side, not only patch 1/3 and patch 3/3
Line 1735:   CC      drivers/tty/serial/samsung_tty.o
Line 343:   CC      drivers/tty/serial/samsung_tty.o

wr_reg_barrier is not defined in patch 1/3, 
and wr_reg_barrier is define and used in patch3/3
it might be no warning.

After I apply this series, I got the above build warning on my normal
x86 system, so I can not take the patches.  Please fix up and resend.
