This is the backport for v4.19.x stable branch.

No code change between v4.14.x and v4.19.x, at least nothing git can not auto-resolve.
Testing wise, this is beyond my testing environment. Although latest GCC compiles without problem, the result kernel can not be properly boot at all, not even any kernel early boot message.
I'm not sure if this is something related to latest edk2 UEFI or something else, I can no longer do proper testing for any older branch, including this 4.19 one.
Thus I can not do any guarantee on these backports, unfortunately the backports can only go to v5.x branches for now.
Unless anyone has better ideas how to build and run older kernels with latest edk2 UEFI environment.
