Moreover, I believe using similar functions as Linux for memory access (copyfromuser, copytouser, get_user, put_user) would be cleaner.

Here is a refresh of the linux-user EFAULT patch vs todays cvs. This patch has now received a lot more runtime, and a couple of bug have been fixed that affected some of the socket APIs. The purpose of this patch is to detect bad pointers and return EFAULT instead of just crashing when the bad pointers are used by qemu. Stuart
