kernel start addr

hello,
I've a little doubt, kernel VA on x86 starts at 0xc0000000 to
0xffffffff and user VA from 0x0 to 0xbfffffff, on x86_64 i just see:

#define __PHYSICAL_START        ((unsigned long)CONFIG_PHYSICAL_START)
#define __START_KERNEL          (__START_KERNEL_map + __PHYSICAL_START)
where __PHYSICAL_START is 0x200000.

kernel VA doesn't start at 0xffff800000000000 to 0xffffffffffffffff
and user VA from 0x0 to 0x0000bfffffffffff ?

Thanks in advance,
