> So we know who is using the bitmap directly

At least all other functions that take a ram_addr_t should be moved
there too:

ram_addr_t qemu_ram_alloc_from_ptr(ram_addr_t size, void *host,
                                   MemoryRegion *mr);
ram_addr_t qemu_ram_alloc(ram_addr_t size, MemoryRegion *mr);
void *qemu_get_ram_ptr(ram_addr_t addr);
void qemu_ram_free(ram_addr_t addr);
void qemu_ram_free_from_ptr(ram_addr_t addr);

So just call it include/exec/ram-addr.h.

Paolo
