Subject: mca: fix bus matching
From: James Bottomley <James.Bottomley@xxxxxxxxxxxx>
There's a bug in the MCA bus matching algorithm in that it promotes from
signed short to int before comparing with the actual id and does sign
extension on anything > 0x7fff (which means that pos ids > 0x7fff never get
correctly matched).
