[Qemu-devel] [PATCH 1/5] i386: Add explicit array size to x86_cpu_vendor_words2str()

[Eduardo Habkost <ehabkost@redhat.com>]

Add explicit array size to x86_cpu_vendor_words2str() to let the
compiler check if we are really passing an array of the right
size.

GCC still doesn't print a warning when the array is too small[1],
but clang already does.
