Re: How to build source kernel
It is also documented in the source... Look in the README file as there are a number of variations.
The big one to remember is to copy a working initial configuration (this saves a LOT of time when starting) with "cp /boot/config-<version> .config" before running "make [menu|x|g|old|silent|...]config" (whichever you choose, and there are a fair number of options). This is where you can make custom configuration selections.
Once the configuration is completed, you can then do
1) make - which builds the kernel
2) make modules -- which builds modules (this step is sometimes dropped)
3) as root: make modules_install install
This last step will create modules (if not already created), install them in /lib, and create the initrd. The "install" target will put the kernel, config file, and initrd in /boot.
On my non-EFI the last steps put the kernel and initrd in /boot.
You will have to edit the grub boot menu to add that custom kernel to the menu.

Most of the time, there is no issue with the kernel (I've done it several times to get patches that haven't yet made it to the repositories, which can take a month or so).
