Hi , I'am little bit confused about this . Do you mean to say User space programs are allocated memory from ZONE_NORMAL:the kernel address space How is this differentiated from the space occupied by the Kernel ? How is the Kernel space protected from user space access then ? I would appreciate if somebody clarifies on this . TIA .
