powerpc: Add show_user_instructions()
show_user_instructions() is a slightly modified version of
show_instructions() that allows userspace instruction dump.
This will be useful within show_signal_msg() to dump userspace
instructions of the faulty location.
Here is a sample of what show_user_instructions() outputs:
pandafault[10850]: code: 4bfffeec 4bfffee8 3c401002 38427f00 fbe1fff8 f821ffc1 7c3f0b78 3d22fffe
pandafault[10850]: code: 392988d0 f93f0020 e93f0020 39400048 <99490000> 39200000 7d234b78 383f0040
The current->comm and current->pid printed can serve as a glue that
links the instructions dump to its originator, allowing messages to be
interleaved in the logs.
