Please do not top post.
A domain may create an arbitrary quantity of hypercall pages, at any
address of their choosing.
You have not explained why you want this information.

C requires that every use of va_copy() is matched with a va_end() call.
This is especially important for x86_64 as va_{start,copy}() may need to
allocate memory to generate a va_list containing parameters which were
previously in registers.

Coverity warns for every occurrence of rand(), which is made worse
because each time the IDL changes, some of the calls get re-flagged.
Collect all calls to rand() in a single function, test_rand(), which
takes a modulo parameter for convenience. This turns 40 defects
currently into 1, which won'
