Virtual address of Global variables in Kernel code

Virtual address of Global variables in Kernel code

If my understanding is not wrong, every process has a Kernel Address space
associated with it (which is typically 1GB). As far as local variables are
concerned, they are assigned on the kernel stack and so their virtual
address is according to the address of the kernel stack. However, if there
are global variables in the kernel code, what will be the virtual address
of these variables? When and who will assign this address? If it is the
compiler, how does the compiler know that some part of code is kernel
code?
Sorry for asking such a naive question, but I am really confused here
