Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the Linux kernel, where the iov iter unit test causes a crash on nommu systems, such as the qemu kc705-nommu emulation. The test calls the vmap() function directly, which is not supported on nommu systems, resulting in a kernel panic. The TEST IOV ITER needs to depend on MMU to prevent this crash.
