From 9ee07f91a1fab61ff0d8d25be43351a049c0a821 Mon Sep 17 00:00:00 2001 From: Nathan Fontenot <nfont@austin.ibm.com> Date: Sat, 26 Jul 2008 04:27:06 +1000 Subject: powerpc: Allow non-hcall return values for lparcfg writes The code to handle writes to /proc/ppc64/lparcfg incorrectly assumes that the return code from the helper routines to update processor or memory entitlement return a hcall return value. It then assumes any non-hcall return value is bad and sets the return code for the write to be -EIO. The update_[mp]pp routines can return values other than a hcall return value. This patch removes the automatic setting of any return code that is not an hcall return value from these routines to -EIO.
