what linear address is the virtual address 0xc000 respondable to ?
the highest 10 bits 0x300 is pde , which means the 0x300th entry of
the page dir.
As I know ,at boot stage , that pde has not been ever filles . then
how does the
kernel code been addressed?

In principle, the linker will associate the kernel code/data to the Kernel
virtual address space i.e. between 0xC000_ to 0x_ and
the same linker will associate the Application's code/data to the user
virtual address space i.e. between 0x_ to 0xBFFF_.
Linker itself cannot d

hi:
I have built vmlinux at the top dir of kernel source ,then I use objdump to
look into
its section information.I find the statup_32 which is the start routine of
kernel ,
locats at 0xc010. I know the 0x10 is the defined address for locating
protect-mode code .But which I can
