Hi John,

The riscv selftests (which were modeled after the arm64 selftests) are
improperly declaring the "emit_tests" target to depend upon the "all"
target. This approach, when combined with commit 9fc96c7c19df
("selftests: error out if kernel header files are not yet built"), has
caused build failures [1] on arm64, and is likely to cause similar
failures for riscv.
To fix this, simply remove the unnecessary "all" dependency from the
emit_tests target. The dependency is still effectively honored, because
again, invocation is via "install", which also depends upon "all".
An alternative approach would be to harden the emit_tests target so that
it can depend upon "all", but that's a lot more complicated and hard to
get right, and doesn't seem worth it, especially given that emit_tests
should probably not be overridden at all.

Andrew,
With this, and with my arm64 fix [2] that you've already put into
mm-unstable, you should be able to safely drop commit 819187ab8741
("selftests: fix arm64 test installation").

thanks,
John Hubbard

Perfect timing, I have just encountered this failure this morning:
make[5]: *** [../../lib.mk:81: kernel_header_files] Error 1
that your patch fixed :) So you can add:
