well, as i mentioned it was and is on the backburner, because we went 
over the same list of problems that you mentioned: harder to read and 
interpret and debug, harder to reproduce boot ordering, etc.

but i'd still like the address the above specific point: it would be 
silly to propagate Kconfig dependencies into the initcall dependencies, 
why do you assume we'd do that?

When PROCFS or PNP is turned off, then their initcall symbols should 
naturally alias to some NOP definition, a function that is immediately 
marked as 'done'. We _already_ have NOP stubs for many initializer 
symbols.

and note:


One convenience symbol would be "memory_done()": to indicate that 
kmalloc() and all the other memory allocators are up and running and 
usable.
