      s390: add proper __ro_after_init support · d07a980c
      Heiko Carstens authored
      On s390 __ro_after_init is currently mapped to __read_mostly which
      means that data marked as __ro_after_init will not be protected.
      Reason for this is that the common code __ro_after_init implementation
      is x86 centric: the ro_after_init data section was added to rodata,
      since x86 enables write protection to kernel text and rodata very
      late. On s390 we have write protection for these sections enabled with
      the initial page tables. So adding the ro_after_init data section to
      rodata does not work on s390.
      In order to make __ro_after_init work properly on s390 move the
      ro_after_init data, right behind rodata. Unlike the rodata section it
      will be marked read-only later after all init calls happened.
      This s390 specific implementation adds new __start_ro_after_init and
      __end_ro_after_init labels. Everything in between will be marked
      read-only after the init calls happened. In addition to the
      __ro_after_init data move also the exception table there, since from a
      practical point of view it fits the __ro_after_init requirements.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      Let it rip!
