Add S390 support for linux-kernel targetusers/arnez/lk3
After implementing the new linux-kernel target and preparing s390-tdep.
It is now time to get everything to work. Thus implement the hooks
required by the linux-kernel target and enable s390's privileged
registers.
gdb/ChangeLog:
* s390-lk-tdep.h: New file.
* s390-lk-tdep.c: New file.
* Makefile.in (ALL_TARGET_OBS): Add s390-lk-tdep.o.
(HFILES_NO_SRCDIR): Add s390-lk-tdep.h.
(ALLDEPFILES): Add s390-lk-tdep.c.
* configure.tgt (s390*-*-linux*): Add s390-lk-tdep.o.
* s390-tdep.h: Define macros for address translation.
* s390-tdep.c (s390-lk-tdep.h): New include.
(s390_iterate_over_regset_sections): Enable privileged registers.
(s390_core_read_description): Enable privileged registers.
(s390_gdbarch_init): : Enable privileged registers and adjust.
