Description someone 2018-10-26 16:24:01 UTC

Description of problem:

Building kernel modules on 4.20-rc0 throws:

Assembler messages:
Error: can't open arch/x86/kernel/macros.s for reading: No such file or directory
Assembler messages:
Error: can't open arch/x86/kernel/macros.s for reading: No such file or director
How reproducible:

with DKMS too.

Adding that file with the one from the upstream tree ends up with a bunch of errors similar to "./arch/x86/include/asm/atomic64_64.h:88: Error: no such instruction: `lock_prefix incq 56(%rax)'".

https://paste.fedoraproject.org/paste/~LQMn7yXbcINWFNr8HVpPg/raw is the log of a failed kernel module building attempt.

This bug doesn't exist on 4.19, and continuing to build modules for 4.19 after installing 4.20-rc0 still works fine.

Comment 1 Justin M. Forbes 2018-10-31 20:39:42 UTC

This should be fixed with the current rawhide build.

@Justin M. Forbes can you point me the fix for this? Is it https://src.fedoraproject.org/cgit/rpms/kernel.git/commit/?id=6904e708917a12819d1fe0d329f605030d6e4b0d ?
