Sorry, this happens only when CONFIG_XEN=y,
and I did not cover all cases.

I will fix it for tomorrow's linux-next.


If it is not too late, you can apply the following locally.



diff --git a/arch/x86/entry/syscalls/Makefile b/arch/x86/entry/syscalls/Makefile
index e1c7ddb7546b..ea6ffb51b9a3 100644
--- a/arch/x86/entry/syscalls/Makefile

+ cmd_hypercalls = $(CONFIG_SHELL) '$<' $@ $(filter-out $<,$(real-prereqs))
