    S390: Support guarded-storage core note sections
    
    Newer Linux kernel versions offer two new register sets in support of the
    z/Architecture's guarded storage facility: NT_S390_GS_CB, the
    "guarded-storage registers", and NT_S390_GS_BC, the "guarded-storage
    broadcast control block".  This patch adds support for the respective core
    notes sections to binutils.
    
    bfd/ChangeLog:
            * elf-bfd.h (elfcore_write_s390_gs_cb): Add prototype.
            (elfcore_write_s390_gs_bc): Likewise.
            * elf.c (elfcore_grok_s390_gs_cb): New function.
            (elfcore_grok_s390_gs_bc): New function.
            (elfcore_grok_note): Call them.
            (elfcore_write_s390_gs_cb): New function.
            (elfcore_write_s390_gs_bc): New function.
            (elfcore_write_register_note): Call them.
    
    binutils/ChangeLog:
            * readelf.c (get_note_type): Add NT_S390_GS_CB and NT_S390_GS_BC.
    
    include/ChangeLog:
            * elf/common.h (NT_S390_GS_CB): New macro.
            (NT_S390_GS_BC): Likewise.
