Will Deacon 91b2d3442f arm64: futex: Mask __user pointers prior to dereference ...

The arm64 futex code has some explicit dereferencing of user pointers
where performing atomic operations in response to a futex command. This
patch uses masking to limit any speculative futex operations to within
the user address space.
