The assembly output of the arch_initr_trap() function differed by a
single byte after common.h was removed from traps.c:
fff49a18 <arch_initr_trap>:
fff49a18: 94 21 ff f0 stwu r1,-16(r1)
fff49a1c: 7c 08 02 a6 mflr r0
fff49a20: 90 01 00 14 stw r0,20(r1)
-fff49a24: 80 62 00 44 lwz r3,68(r2)
+fff49a24: 80 62 00 38 lwz r3,56(r2)
fff49a28: 4b ff 76 19 bl fff41040 <trap_init>
fff49a2c: 80 01 00 14 lwz r0,20(r1)
fff49a30: 38 60 00 00 li r3,0
fff49a34: 38 21 00 10 addi r1,r1,16
fff49a38: 7c 08 03 a6 mtlr r0
This was causing a consistent hard lockup during the MMC read / loading
of the QoriQ FMan firmware on a P2041RDB board.
Re-adding the header causes identical assembly to be emitted and allows
the firmware loading and subsequent boot to succeed.
