Several posters are asking for the mainline builds to be fixed. The mainline builds are an exact reflection of the upstream git master repositories. Therefore they have to wait for Seth's patch submission, which has been picked up and accepted by the kbuild team, to propagate it's way to the mainline upstream git branch. Earlier today, a kernel 5.3-rc1 merge request was issued by the kbuild team [1]. Once that branch has been "pulled" into the upstream mainline, the Ubuntu mainline daily compiles should start working the next day. In about 8 days there will be kernel 5.3-rc1, which should have the patch.

This appears to be due to the changes in 9.1.0-3ubuntu1 enabling -fcf- protection by default on 19.10's gcc-9. Switching to gcc-8 allows compilation to proceed.
