The variable ansible_processor, on Linux it is parsing /proc/cpuinfo line by 
line while looking for 
'model name', 'Processor', 'vendor_id', 'cpu', 'Vendor', 'processor'

The first one it find become element 0 and the second becomes element 1 and so 
So if your /proc/cpuinfo differ you will get different result on different host.

So if you host1 and host2 is Linux it did not find processor on host1 because 
it does not exist in /proc/cpuinfo therefor the element 0 in the list become 
the vendor_id instead since it found that first.

This make ansible_processor unpredictable and you should probably find the 
information yourself.
