Thanks a lot. As always, you've been very helpful. I appreciate your 
willingness to help and, more generally, your attitude towards people with 
less experience than yours.

By using F8, I found that CONFIG_LOCKDEP is selected by CONFIG_LOCK_STAT (in 
logical AND with other options) but, in my .config, the latter was set to 'n'. 
After setting this other option to 'y', CONFIG_LOCKDEP magically :) appeared  
in .config and it was automatically set to 'y'.

I see that the same kind of search can also be done by using the slash if one 
uses "make menuconfig".
