Thank you. Now the first 2 questions are cleared.

Thanks again.

First, I doubt whether all processes share one

its own "u".
Every process has its own u-area.
They have all at the same virtual kernel address,
but live in different physical locations.
So isn't it saying that there's only
one "u" in the core memory?
No. The running process' u-area is mapped into
the virtual address space before executing any
instructions of the process.
