How to build an upstream Fedora Kernel from source
I typically keep my Fedora system current, updating it once every week or two. More recently, I wanted to test the Idle Page Tracking feature, but this wasn’t enabled in the default kernel provided by Fedora.
# grep CONFIG_IDLE_PAGE_TRACKING /boot/config-$(uname -r)
# CONFIG_IDLE_PAGE_TRACKING is not set
