Porting Linux to a new architecture -- the right way

Every year, we see a few new architecture ports getting merged into the Linux kernel, but unfortunately each one copies the same bugs from the existing architectures, creating a huge mess in system call interface differences and implementation bugs.

In an attempt to simplify the work for future architecture ports, we will try to provide generic implementations for almost all architecture specific functions, and describe the minimally necessary implementation for a new port.
