Why do we need separate kernel stack for each process? A separate kernel stack is needed for each process to save the state of the process. The state needs to be saved in case a task switch is performed, i.e. the current process is put to sleep, and some other process scheduled to run.
Why do we need a per process kernel stack? Each process has a kernel stack (or more generally, each thread has its own stack) Just like there has to be a separate place for each process to hold its set of saved registers (in its process table entry), each process also needs its own kernel stack, to work as its execution stack when it is executing in the kernel.

Is the kernel an invariant subspace? The kernel of an operator, its range and the eigenspace associated to the eigenvalue of a matrix are prominent examples of invariant subspaces.
