Summary
lib/Kconfig.debug: TEST_IOV_ITER depends on MMU
Details

In the Linux kernel, the following vulnerability has been resolved:

lib/Kconfig.debug: TESTIOVITER depends on MMU

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. TESTIOVITER therefore needs to depend on MMU.
