It's probably a bug fix that unveils the link errors.
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master head: c786427f57b6dc4f56f9a84da52b41216e94f125 commit: c20164dbd508c410f5d5f6b121e6cfae7c2da8ba drm/i915/gvt: always use i915_reg_t for MMIO handler definition date: 8 weeks ago config: x86_64-randconfig-h0-02181955 (attached as .config) compiler: gcc-7 (Debian 7.3.0-1) 7.3.0 reproduce: git checkout c20164dbd508c410f5d5f6b121e6cfae7c2da8ba # save the attached .config to linux build tree make ARCH=x86_64
