Log: powerpc: Add display of raw instruction values to x/I in ddb. The "alternate format" character 'I' previously had the same behavior as the "display as an instruction" character 'i'. With this change, it will now prefix each disassembled instruction with the raw hex value. As PowerPC instructions are always 32 bits and always aligned, and there are no alternate modes that would affect instruction decoding or display, this seemed to me to be the obvious interpretation of "alternate format".
