[Qemu-devel] [PATCH v2 08/11] exec: move qemu_ram_addr_from_host_nofail to cputlb.c

[Paolo Bonzini <pbonzini@redhat.com>]

After the next patch it would not be used elsewhere anyway.  Also,
the _nofail and the standard versions of this function return different
things, which is confusing.  Removing the function from the public headers
limits the confusion.
