Hello,
While trying to compile the current version of QEMU I've got the following

I'm not sure why vm_map.h gets included there, but in any case having macro
names like max_offset is asking for trouble. I would like to ask for feedback,
but IMO the easier way to solve this is to rename the macro to VM_MAX_OFFSET
(and VM_MIN_OFFSET).
