The patch titled
x86_64: Add compat_sys_vmsplice and use it in x86-64
has been removed from the -mm tree. Its filename is
x86_64-add-compat_sys_vmsplice-and-use-it-in.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
