From 089545f0c71bab6511395c2a060d7f81a99bad58 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Fri, 6 Jan 2006 00:19:12 -0800 Subject: [PATCH] s390: cputime_t fixes There are some more places where the use of cputime_t instead of an integer type and the associated macros is necessary for the virtual cputime accounting on s390. Affected are the s390 specific appldata code and BSD process accounting.
