find, xargs, and wc are your friends. For Linus's 'git' tree (3.14-rc8-ish):

[/usr/src/linux] find * -type d | wc -l
2947
[/usr/src/linux] find * -type f | wc -l
46016
[/usr/src/linux] find * -type f -name '*.[ch]' | xargs cat | wc -l
16644991

(Ignoring of course that there's other types of lines of code besides *.c
and *.h.  If you don't like it, do your own find command :)
