0) Untested.

1) A very similar commit is 10b5aabddd1e ("[PATCH]
include/asm-h8300/page.h: remove unused KTHREAD_SIZE #define"). I found
that commit by looking into the history of the unloved
CONFIG_SMALL_TASKS macro. References to it were added to (a few places
in) the tree, starting with v2.5.46. But I haven't found evidence that
it was ever defined.
