Hi,
The wireguard module (0.0.20181119 from Debian Unstable) fails to build on
my machine using kernel 4.20 rc4.

I get the following errors:

# cat /var/lib/dkms/wireguard/0.0.20181119/build/make.log

Hi,
It builds with 4.19.x. What happened to 4.20?
On the Fedore bug tracker there is something related:

https://src.fedoraproject.org/cgit/rpms/kernel.git/commit/?id=6904e708917a12819d1fe0d329f605030d6e4b0d

Probably not. I don't have any "arch/x86/kernel/macros.s" file (actually
"/usr/src/linux-headers-4.20.0-rc4/arch/x86/kernel/macros.s") at all. In
fact neither do i have macros.s or macros.S in previous kernels directories.

I think the issue isn't with the WireGuard code but with something
unique to Debian or to dkms.  I am able to build the module on Arch
Linux using 4.20-rc4 (linux-mainline package from the AUR) with issue.
I haven't tried dkms (not a fan).

Here is a PKGBUILD for wireguard tools and module without using DKMS:

And that's why it fails[1]. You have to add "arch/x86/kernel/macros.s" to list of files
