For reserved_va & ~MAP_FIXED mmap, linux-user and bsd-user translates it

an assertion failure.
This series fixed it for linux-user and bsd-user and added test
coverage. For start > reserved_va, skip [start, reserved_va] and just
search within [min_addr, reserved_va].
I actually thought that I am adding too many CC's and causing
unnecessary noise but b4 is asking me to run auto-to-cc (:

linux-user: Deal with mmap where start > reserved_va
Hi!
This smells like qemu-stable change.
bsd-user: Deal with mmap where start > reserved_va
I'm not sure this one should be picked up too, but since
it's basically the same as for linux, I'd say it should, too.
tests/tcg/multiarch/test-mmap: Print more details
tests/tcg/multiarch/test-mmap: Check mmaps beyond reserved_va
And probably the tests, too.
Please let me know if I shouldn't pick these up.
Thanks,
