I tested the riscv64 cross-build of linux-kbuild on amd64 with 6.12.27-1 and 7.2.6-1. The old version still fails with the missing asm/fence.h error, while the new version builds successfully. I suspect commit 9d2a04763e4f [1] is related, since it adds HOSTARCH=$(KERNEL_ARCH) to the resolve_btfids build. Could this be closed as fixed in 7.2.6-1? If the stable 6.12 packaging branch is still affected, would it be worth backporting this change?
