Hello All,
I have a question about page tables initialization in the
arch/x86/boot/compressed/head_64.S
After we clear memory for page tables, there is code which
build PML4:
leal pgtable + 0(%ebx), %edi
leal 0x1007(%edi), %eax
movl %eax, 0(%edi)
Why there is offset 0x1007 instead just 0x7? 0x1007 is
4k + 7bit (PML4E) flags as i understand correctly. But
why we skip first 4k here?
Thank you.
