I've been trying to compile, build and install the latest stable version of the Linux kernel, 5.7.7.I first downloaded and unzipped the tar. Next, I ran cp /boot/config-$(uname -r) .config, followed by make menuconfig
In the menuconfig menu, I figured since I was using a VBox VM, it might help to turn all VBOX configurations to Y. So, I did that, and I also turned LOCALVERSION_AUTO to Y as well (unrelated, but that was my only extra requirement).
However, after running make, I encounter something like this a few times, for different object files.
kernel/exit.o: warning: objtool: __x64_sys_exit_group()+0x18: unreachable instructionI'm running the latest build of Ubuntu 20.04.
Could someone please tell me what's going wrong, and how I can fix this? Is this an issue exclusively found in Virtual Machines using VirtualBox only? Also, what extra issues could this possibly give rise to?
