Errors are caused by removal of the stacktrace mechanism that kpatch was using. Found this which seems to be aimed at addressing this issue: https://github.com/dynup/kpatch/pull/659.

Attaching a backport of https://github.com/dynup/kpatch/commit/586feb40fe116b70d3ac752359706c3e1fafe4ea. I've tested build and load of the dkms module with xenial, yakkety, and zesty-4.10 kernels with this patch applied.

   * Upstream bump to 0.5.0 (LP: #1763065).

     - kmod-core-fix-stacktrace_ops-address-function-protot.patch
     - create-diff-object-fix-WARN-_ONCE-detection-on-newer.patch
     - use-livepatch-4.5-kernel-features.patch
   * output-kernel-build-in-debug.patch was dropped to reduce build output.

     upstream:
     - kpatch-build-adjust-dirs.patch
     - use-debian-rules-for-ubuntu-builds.patch

   * The shellcheck linter is called during packaging, to verify the quality of
     the scripts used in the package.
   * List the Ubuntu Kernel Team as the package maintainer in the control file
   * kmod/core: fix stacktrace_ops 'address' function prototype for 4.6 (LP: #1665613, #1659581)
