From 058ac308f3dd34ce4e2dbf938258975ced14b809 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Tue, 16 Oct 2007 01:27:17 -0700 Subject: uml: coredumping floating point fixes Fix core dumping of floating point state. ELF_CORE_COPY_FPREGS gets a definitions, and as a result, dump_fpu no longer needs to exist. Also, elf_fpregset_t needed a real definition.
