From 0a0d9fa7c85c5474870cae37832d28ccd899d4ee Mon Sep 17 00:00:00 2001
From: "Richard W.M. Jones" <rjones@redhat.com>
Date: Fri, 4 Oct 2019 15:57:42 +0300
Subject: [PATCH 1/8] Fix virt-what-cpuid-helper.
The value returned in %eax is the max_entry (eg. 0x40000000
if there are no further leafs). However it is not reliable.
In addition if there are multiple leafs we should probably
only print the highest one.
Also use uint32_t instead of unsigned int.
Thanks: Paolo Bonzini.
