This includes code general for the architecture as well as code specific for uses in GNU/Linux (user space). Up until now this was ok as GNU/Linux was the only supported OS. In preparation to support the new Linux kernel 'OS' split up the existing s390 code into a general s390-tdep and a GNU/Linux specific s390-linux-tdep. gdb/ChangeLog: * s390-tdep.h: New file. * s390-tdep.c: New file. * s390-linux-nat.c (s390-tdep.h): new include. * Makefile.in (ALL_TARGET_OBS): Add s390-tdep.o.
