Comment 15 for bug 1591521

Update : Still working this ... it is taking longer than I had hoped.

I feel like a dummy but I am having issues building the older kernels from git.

The 4.4.13 and the 4.7rc6 built and ran, no problem

but during the bisect building the 3.13.0-24.47 to 3.15.0-1.3 kernels have been an issue.
Using an Ubuntu 16.04 base OS, the kernel Makefile needed to be changed, setting CC=gcc-4.8, or it would not compile, complaining about gcc5 header files missing.

after changing the makefile, it then built ok but when the .deb kernel-image packages are installed and the system rebooted the OS dies immediately after grub loading initramfs, with a message from the vm manager saying the host os has disabled the cpu.

I then tried rebuilding on an older (slower!) 14.04 machine and that worked, built and ran fine if i scp'd .deb's over to the VM and tested.

Now the bisect has brought me to 3.15 and the debian/rules folder has been deleted,
which is what I was using here : https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel
I am now looking at this :
https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
which doesn't require the debian/ folder.
Any suggestions?, I am going about this the correct way?
