From 0576fc703a03a43e73a57450d5720b47ec7a03ba Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 25 Oct 2010 16:10:42 +0200 Subject: [PATCH] [S390] smp: use correct cpu address in print_cpu_info() Up to now print_cpu_info() uses the cpu address stored in it's local lowcore to print a message to the console. The cpu address in the lowcore is (in this case) however not the physical cpu address of the local cpu. It's the address of the cpu that issued the sigp restart which started the local cpu. Fix this by using the store cpu address instruction instead. It's not that anybody really cares since this is broken since more than ten years...
