memcpy can take a large amount of time for small reads and writes. Handle the common case of reading s/g descriptors from memory (there is no corresponding "write" case that is as common, because writes often use address_space_st* functions) by inlining the relevant parts of address_space_read into the caller. Backports commit 3cc8f884996584630734a90c9b3c535af81e3c92 from qemu |
