From d4261662b67b48e52f747ee1e3c31cf873c5c982 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Mon, 29 Apr 2013 18:33:51 +0000 Subject: pseries: Factor out check for out-of-bounds LIOBN PAPR defines LIOBNs (Logical IO Bus Numbers) to be 32-bit, and we check for values that aren't in the code for H_PUT_TCE. This patch factors the check into spapr_tce_find_by_liobn(), which already checks if a 32-bit LIOBN actually exists. This will become more important as future patches add other hypercalls which need to look up a LIOBN. At the same time we fix the typo in the message.
