Unless I totally misunderstand, the Linux Kernel does not have any
libraries. It's core is a monolithic program to which modules can be
loaded. To think of it as a library is not instructive in my mind.

Again the kernel core is not a library, but the linux kernel core is
primarily written in C, but some of the functions are indeed in
Note that ANSI C is not precisely the language in question. Many GCC
extensions are used. One example is the keyword, "unlikely".

The GCC manuals are a necessary reference as well. You can find them online.

In general you can avoid most assembly if you are not porting the
kernel to a new cpu/MB/chipset.
