Mainline kernel build failure for i386 and amd64 - v5.2.1, v5.1.18 [error: '-mindirect-branch' and '-fcf-protection' are not compatible]

[Tony George]

The mainline kernel builds on kernels.ubuntu.com are in failed state for the latest kernel versions.

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.2.1/
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.2/
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1.17/
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.1.18/

Build seems to have failed for i386 and amd64 but succeeded for other architectures.

Sounds like bug 1830961, which was closed just today.

I guess the problem here is that this bug is reported against the wrong component... The 'linux' source package is not the mainline kernel, it's the Ubuntu kernel :)
