Subject: [PATCH] target-i386: Fix x86_cpuid_set_model_id()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Don't assume zeroed cpuid_model[] fields.

This didn't break anything yet but QOM properties should be able to set
the value to something else without setting an intermediate zero string.

[AF: Use memset() instead of for loop, suggested by Igor]
