Zero. Just 5 kernel stacks - one for every user space thread; This stack is
used when a user space thread executes a syscall. In the kernel this is
software interrupt context. On x86 systems which do not have the syscall
instruction the syscall is executed by moving the arguments in the register
and then executing "int 0x80". Do not mix it with SoftIRQ, this is something
completly different.

What is a kernel process? I thought Linux is a monolithic kernel and executes
everything in the same address space...
