hi,
when I load a module and in this module there is:
unsigned long cr3;
asm("xor %%rbx, %%rbx\t\nmov %%cr3, %0" : "=b" (cr3));
what cr3 is? insmod in userspace or cr3 in kernel space?
CR3 is a register on x86 and x86-64 chips, that points to the page
directory (highest level page table) for the current process.
