I saw no problems on 8 of 9 machines, but the last one had a problem because it used NVIDIA drivers (387); DKMS reported:
FATAL: modpost: GPL-incompatible module nvidia-drm.ko uses GPL-only symbol 'ex_handler_refcount' //usr/src/linux-headers-4.14.0-11-common/scripts/Makefile.modpost:92: recipe for target '__modpost' failed make[3]: *** [__modpost] Error 1
Is this a new issue? Does 4.14.4 have this issue?
I believe it is a new issue, because I have a 4.14.4 build and an NVIDIA DKMS log for that 4.14.4 showing build success.
Odd, is 564c9cc84e2a ("locking/refcounts, x86/asm: Use unique .text section for refcount exceptions") causing this?
That was my guess too, but I did not verify.
That feels really wrong here, I'd like to get some confirmation before I add this patch...
I built a 4.14.4 with all the stable-queue patches except:
locking/refcounts, x86/asm: Enable CONFIG_ARCH_HAS_REFCOUNT
and NVIDIA built fine with DKMS, so it looks like the refcount enablement patch was responsible.
In summary, NVIDIA builds fine with
4.14.4 4.14.4 + all stable-queue except ...Enable CONFIG_ARCH_HAS_REFCOUNT 4.14.4 + all stable-queue + https://lkml.org/lkml/2017/12/4/1110
Thanks,
