whinges, perrmanits, maybe I'm doing it wrong, etc.
a)
At the top-level, neither `make mrproper' nor `make clean' remove the
executables from tools/testing/selftests/mm/. Seems wrong?
b)
Shouldn't I be able to run
make selftests
from the top level?
c)
tools/testing/selftests/mm
make clean
make
does:
CC droppable
CC guard-regions
CC merge
CC rmap
CC soft-dirty

why did it start emitting the gcc command lines?
d) within tools/testing/selftests/mm:
make clean
make -j100
compiles 3-4 things then ends.
A subsequent `make -j1' compiles nothing.
Whereas
make clean
make -j1
compiles everything. Slowly.
Thanks.
