Subject: [patch] clean hex output of ftrace

Fix the output of ftrace in hex mode. Without this patch, the ouput of ftrace is :

raw mode : 6474 0 141531612444 0 140 + 6402 120 S
hex mode : 000091a4 00000000 000000023f1f50c1 00000000 c8 000000b2 00009120 87 ffff00c8 00000035

There is an inversion on ouput hex(6474) is 194a
