From ab310b5edb8b601bcb02491ed6f7676da4fd1757 Mon Sep 17 00:00:00 2001 From: Jason Wessel Date: Tue, 30 Mar 2010 14:05:07 -0500 Subject: x86,kgdb: Always initialize the hw breakpoint attribute It is required to call hw_breakpoint_init() on an attr before using it in any other calls. This fixes the problem where kgdb will sometimes fail to initialize on x86_64.
