dump: Make DumpState and endian conversion routines available for arch-specific dump code
Make DumpState and endian conversion routines available for arch-specific dump code by moving into dump.h. DumpState will be needed by arch-specific dump code to access target endian information from DumpState->ArchDumpInfo. Also break the dependency of dump.h from stubs/dump.c by creating a separate dump-arch.h. This patch doesn't change any functionality. Signed-off-by: Bharata B Rao <bharata@linux.ibm.com> [ rebased on top of current master branch, renamed endian helpers to cpu_to_dump{16,32,64}, pass a DumpState * argument to endian helpers, Greg Kurz <gkurz@linux.vnet.ibm.com> ] Signed-off-by: Greg Kurz <gkurz@linux.vnet.ibm.com> [agraf: fix to apply] Signed-off-by: Alexander Graf <agraf@suse.de>
