lib/Kconfig.debug: TEST_IOV_ITER depends on MMU
commit 1eb1e984379e2da04361763f66eec90dd75cf63e upstream.
Trying to run the iov_iter unit test on a nommu system such as the qemu
kc705-nommu emulation results in a crash.
KTAP version 1
# Subtest: iov_iter
# module: kunit_iov_iter
1..9
BUG: failure at mm/nommu.c:318/vmap()!
Kernel panic - not syncing: BUG!
The test calls vmap() directly, but vmap() is not supported on nommu
systems, causing the crash. TEST_IOV_ITER therefore needs to depend on
MMU.
