Why is 'int fd' changed to 'unsigned long fd'?  

Because preadv2 and pwritev2 take "unsigned long". I want vmsplice
to be as similar as possible to preadv2 and pwritev2.

Something needs to ensure that the high 32bits of the fd get masked off
on 64bit systems.
They can be non-zero in the register that comes from userspace.

Should that be its own commit if the change is desired?  

Yes, possibly. But this patchset already got to next.
