1, stack of virtual memory mapped to the actual physical memory is discontinuous, isn't it?

2, the stack pointer register storage stack pointer RSP is virtual memory, which is a virtual address, is it?

3, when the CPU to call a function that will return address, and the parameters of the function parameters (too much), is
Save register, pressure into the stack for local variables of these by the stack data is stored in memory?
If so, how the CPU through the stack pointer RSP (virtual address) to access the data in memory? Is the data
Pressure into the stack, build a page table will pressure into the physical address of data stack and match them with the virtual address?
