From 6e6d74cfac782a3a4cb5111bd9c25cd95d6b7c6c Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sat, 10 Feb 2007 01:44:30 -0800 Subject: [PATCH] uml: x86_64 ptrace fixes This patch fixes some missing ptrace bits on x86_64. PTRACE_ARCH_PRCTL is hooked up and implemented. This required generalizing arch_prctl_skas slightly to take a task_struct to modify. Previously, it always operated on current. Reading and writing the debug registers is also enabled by un-ifdefing the code that implements that. It turns out that x86_64 is identical to i386, so the same code can be used.
