Can you test this scratch build? It copies the module linker script over to kernel-devel https://koji.fedoraproject.org/koji/taskinfo?taskID=24002514 The scratch RPMs fix the problem:
[root@apm-mustang-ev3-03 ~]# uname -a
Linux apm-mustang-ev3-03.lab.eng.rdu.redhat.com 4.14.11-301.fc27.aarch64 #1 SMP Fri Jan 5 00:11:51 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux
[root@apm-mustang-ev3-03 ~]# stap -e 'probe begin {printf("hello\n"); exit()}'
hello
I committed the patch to all branches.

Description of problem: The kernel-devel is missing ./arch/arm64/kernel/module.lds and anything that that attempts to build a kernel module will fail with: ld: cannot open linker script file ./arch/arm64/kernel/module.lds: No such filey make[4]: *** [scripts/Makefile.modpost:129: /tmp/stapYqdiNY/stap_e99ec35f6fd8a51 make[3]: *** [Makefile:1515: modules] Error 2 WARNING: kbuild exited with status: 2 Version-Release number of selected component (if applicable): kernel-devel-4.14.11-300.fc27.aarch64 How reproducible: Every time Steps to Reproduce as root: 1. dnf install "systemtap*" kernel-devel 2. stap -e 'probe begin {printf("hello\n"); exit()}' Actual results: ld: cannot open linker script file ./arch/arm64/kernel/module.lds: No such file or directory make[1]: *** [scripts/Makefile.modpost:129: /tmp/stapdjV8Fy/stap_7336d901e3099a6abf2bd41dcaf0d0c3_991.ko] Error 1 make: *** [Makefile:1515: modules] Error 2 WARNING: kbuild exited with status: 2 Pass 4: compilation failed.
