page table fault, which should map kernel virtual address space

Hallo, this is about 'NKPT' definition, 'kernel_map' submaps, and 'vm_map_findspace' function. Variable 'kernel_map' is used to manage kernel virtual address space. When 'vm_map_findspace' function deals with 'kernel_map' then 'pmap_growkernel' function is called. At least in 'i386' architectur
