build kernel/profile.o only when requested
Build kernel/profile.o only if CONFIG_PROFILING is enabled.
This makes CONFIG_PROFILING=n kernels smaller.
As a bonus, some profile_tick() calls and one branch from schedule() are
now eliminated with CONFIG_PROFILING=n (but I doubt these are
measurable effects).
This patch changes the effects of CONFIG_PROFILING=n, but I don't think
having more than two choices would be the better choice.
This patch also adds the name of the first parameter to the prototypes
of profile_{hits,tick}() since I anyway had to add them for the dummy
functions.
