This series reworks core ftrace support on powerpc to have the function
profiling sequence moved out of line. This enables us to have a single
nop at kernel function entry virtually eliminating effect of the
function tracer when it is not enabled. The function profile sequence is
moved out of line and is allocated at two separate places depending on a
new config option.

Applied to powerpc/next.
