Merge branch 'work.fdpic' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull fdpick coredump update from Al Viro: "Switches fdpic coredumps away from original aout dumping primitives to the same kind of regset use as regular elf coredumps do" * 'work.fdpic' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: [elf-fdpic] switch coredump to regsets [elf-fdpic] use elf_dump_thread_status() for the dumper thread as well [elf-fdpic] move allocation of elf_thread_status into elf_dump_thread_status() [elf-fdpic] coredump: don't bother with cyclic list for per-thread objects kill elf_fpxregs_t take fdpic-related parts of elf_prstatus out unexport linux/elfcore.h
