The original port of ftrace to PowerPC kept a lot of the code used by x86. Some of this code was to handle x86's 5 byte instruction. This was handled by using character arrays to manipulate the code. PowerPC has a consistent 4 byte instruction. Using unsigned ints makes the code more efficient as well as more readable. By converting to use unsigned ints to represent instructions, I was able to remove the side effects that were needed for manipulating character strings. i.e. memcpy and memcmp Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
