From d1254b12c93e1e586137a2ffef71fd33cf273f35 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Thu, 30 Aug 2007 23:56:20 -0700 Subject: uml: fix x86_64 core dump crash Stop UML crashing when trying to dump a process core on x86_64. This is the minimal fix to stop the crash - more things are broken here, and patches are forthcoming. The immediate thing to do is define ELF_CORE_COPY_REGS and ELF_CORE_COPY_FPREGS. Defining ELF_CORE_COPY_FPREGS allows dump_fpu to go away. It is defined in terms of save_fp_registers, so that needs to be added.
