parisc: Switch to more fine grained lws locks Increase the number of lws locks to 256 entries (instead of 16) and choose lock entry based on bits 3-11 (instead of 4-7) of the relevant address. With this change we archieve more fine-grained locking in futex syscalls and thus reduce the number of possible stalls.
