From a8b4fc4d7c3ccf80d4fa1805cee85c06c2aa653e Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Wed, 27 Sep 2006 01:50:35 -0700 Subject: [PATCH] uml: fix missing x86_64 register definitions The UML/x86_64 headers were missing ptrace support for some segment registers. The underlying problem was that the x86_64 kernel uses user_regs_struct rather than the ptrace register definitions in ptrace. This patch switches UML/x86_64 to using user_regs_struct for its definitions of the host's registers.
