From 92b8e39c7f582e15f9e9423bc9fd3f186536b073 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 6 Nov 2013 20:25:21 +0200 Subject: spapr_pci: s/INT64_MAX/UINT64_MAX/ It doesn't make sense for a region to be INT64_MAX in size: memory core uses UINT64_MAX as a special value meaning "all 64 bit" this is what was meant here. While this should never affect the spapr system which at the moment always has < 63 bit size, this makes us hit all kind of corner case bugs with sub-pages, so users are probably better off if we just use UINT64_MAX instead.
