The quilt patch titled Subject: lib/Kconfig.debug: TEST_IOV_ITER depends on MMU has been removed from the -mm tree. Its filename was lib-kconfigdebug-test_iov_iter-depends-on-mmu.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Guenter Roeck <linux@xxxxxxxxxxxx> Subject: lib/Kconfig.debug: TEST_IOV_ITER depends on MMU Date: Thu, 8 Feb 2024 07:30:10 -0800 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.
