From 7e180bd8020d213bb0de15c3606968f8a9262439 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Sun, 11 Mar 2012 11:59:25 -0400 Subject: [S390] rename lowcore field The 16 bit value at the lowcore location with offset 0x84 is the cpu address that is associated with an external interrupt. Rename the field from cpu_addr to ext_cpu_addr to make that clear.
