[Xen-devel] [PATCH 1/3] x86/cpuid: fix generation of auto cpuid header

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

The makefile rule to generate the cpuid-autogen.h header passes the
whole list of dependencies to gen-cpuid.py but only the first
dependency is actually needed.

So far this seems to be harmless.
