There's been complaints about trace_printk() being defined in kernel.h as it
can increase the compilation time. As it is only used by some developers for
debugging purposes, it should not be in kernel.h causing lots of wasted CPU
cycles for those that do not ever care about it.

Do we have a measurement of the increased compilation time ?

I believe Yury does.
