[Qemu-devel] [PATCH 1/2] ioport: use INT64_MAX for IO ranges


From: Blue Swirl
Subject: [Qemu-devel] [PATCH 1/2] ioport: use INT64_MAX for IO ranges
Date: Sun, 18 Mar 2012 12:04:02 +0000

Expression UINT64_MAX + 1 will make the range bigger than
what can be represented with a 64 bit type. This would
trigger an assert in int128_get64() after the next patch.
