The generic asm futex implementation emulates atomic access to memory by doing a get_user followed by put_user. These translate to two mapping operations on UML with paging enabled in the meantime. This, in turn may end up changing interrupts, invoking the signal loop, etc. This replaces the generic implementation by a mapping followed by an operation on the mapped segment.
