Subject[PATCH 3/7] kbuild: doc: fix 'List directories to visit when descending' section
Date
Fix state information:

- Fix the section number in the reference from 6.4 to 7.4.

- Remove init-y and net-y. They were removed by commit 23febe375d94
("kbuild: merge init-y into core-y") and commit 95fb6317b3ab
("kbuild: merge net-y and virt-y into drivers-y"), respectively.

- Update the example because arch/sparc64/Makefile does not exit.
