This sounds interesting, but does it come with the same "Only gets 2GB

In other words you reserve some address space below 2G by using
mmap(NULL, length, PROT_NONE, MAP_32BIT | MAP_ANONYMOUS, 0, 0) and then
use mremap(addr64bit, 0, length, MREMAP_FIXED, reserved_addr).

So, it sounds like something like an OpenGL equivalent of
VK_EXT_map_memory_placed would be more palatable?
While we're at it, something like VK_EXT_map_memory_placed that also allows
