From 6772926bef3c9f0ec761b39e5702535471fff70b Mon Sep 17 00:00:00 2001 From: Rusty Lynch Date: Tue, 5 Jul 2005 18:54:50 -0700 Subject: [PATCH] [PATCH] kprobes: fix namespace problem and sparc64 build The following renames arch_init, a kprobes function for performing any architecture specific initialization, to arch_init_kprobes in order to cleanup the namespace. Also, this patch adds arch_init_kprobes to sparc64 to fix the sparc64 kprobes build from the last return probe patch.
