peterz@infradead.org 698eb82638 futex: Validate futex value against futex size ...

Ensure the futex value fits in the given futex size. Since this adds a
constraint to an existing syscall, it might possibly change behaviour.

Currently the value would be truncated to a u32 and any high bits
would get silently lost.
