One thing I just noticed: Each VMA seems to be some multiple of PAGE_SIZE (4096 on i386). Does this mean that each VMA is made up of a number of "virtual pages" (even though Linux seems to have no data struct for this) and each one is PAGE_SIZE bytes?
Yes. To keep things simple, PAGE_SIZE refers to the size of both the virtual and physical pages. This is dependent on the CPU architecture. For instance, I think some Sparc (or is it Alpha?) processors have 8KB pages.
Does this also mean that each one of those 'virtual pages' maps directly onto a physical page, so every address in the between PAGE_SIZE byte boundaries in a VMA will map to the exact same physical page?
Yes.
