Just saw Chris posted a fix to the list, please disregard this.

We had competing reverts/disable commits go in that caused issues with each other.
Christian committed 783195ec1cad ("drm/syncobj: disable the timeline UAPI for now v2"), which moved the CREATE_TYPE_TIMELINE #define internally and added a check in drm_syncobj.c. When Eric reverted the entire timeline patch, he cleaned up the #define in the new location, but failed to remove the check, causing the boom.
The error:
../drivers/gpu/drm/drm_syncobj.c: In function ‘drm_syncobj_create’: ../drivers/gpu/drm/drm_syncobj.c:281:14: error: ‘DRM_SYNCOBJ_CREATE_TYPE_TIMELINE’ undeclared (first use in this function); did you mean ‘DRM_SYNCOBJ_CREATE_SIGNALED’? if (flags & DRM_SYNCOBJ_CREATE_TYPE_TIMELINE) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ DRM_SYNCOBJ_CREATE_SIGNALED ../drivers/gpu/drm/drm_syncobj.c:281:14: note: each undeclared identifier is reported only once for each function it appears in
