Hi There :) I've Stumbled Upon This Issue While Trying To Upgrade a 'musl-libc' Based System, From 'sys-kernel/gentoo-sources-5.11.22' To 'sys-kernel/gentoo-sources-5.12.5'. Some Folks at 'Samsung' Seem To Have Stumbled Upon That Issue Too & They've Found/Proposed a Simple - 3-Liner - Fix on LKML, by 10/12/2020. Reproducible: Always Steps to Reproduce: 1. Do a Plain 'emerge -av =sys-kernel/gentoo-sources-5.12.5' . Actual Results: /usr/src/linux # make modules_prepare <...> CALL scripts/checksyscalls.sh CALL scripts/atomic/check-atomics.sh DESCEND objtool CC

Created attachment 710361 [details, diff] uapi/linux/swab.h patch for musl What version of sys-kernel/linux-headers are you using? I found the patch below worked for me when using sys-kernel/linux-headers-5.4 but may need updating for newer versions. I will have a look-see as to what source I was using for this, but I suspect there were a few likely candidates. From memory something came up on the lkml iirc ..
