flush it manually.
The benefit here is that you can

Hi folks,
I've been updating some old patches which make use of a function to
translate guest virtual addresses into pointers into the guest RAM.
As I understand it qemu has guest virtual and physical addresses, the
latter of which map somehow to host ram addresses.
The function which the code
