      increase AT_VECTOR_SIZE to terminate saved_auxv properly · 4f9a58d7
      Olaf Hering authored
      include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO.  fs/binfmt_elf.c
      has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT
      entries.  So in the worst case, saved_auxv does not get an AT_NULL entry at
      the end.
      
      The saved_auxv array must be terminated with an AT_NULL entry.  Make the
      size of mm_struct->saved_auxv arch dependend, based on the number of
      ARCH_DLINFO entries.

      powerpc: add Altivec/VMX state to coredumps · 1f7d6668
      Mark Nelson authored
      Update dump_task_altivec() (which has so far never been put to use) so that
      it dumps the Altivec/VMX registers (VR[0] - VR[31], VSCR and VRSAVE) in the
      same format as the ptrace get_vrregs(), and add the appropriate glue
      typedef and #defines to make it work.
      
      A new note type of NT_PPC_VMX was chosen to be 0x100 (arbitrarily) because
      it allows the low range values to be used for more generic purposes and
      0x100 seems an adequate starting point for PowerPC extensions.

      [POWERPC] spufs: Cleanup ELF coredump extra notes logic · e5501492
      Michael Ellerman authored
      To start with, arch_notes_size() etc. is a little too ambiguous a name for
      my liking, so change the function names to be more explicit.
      
      Calling through macros is ugly, especially with hidden parameters, so don't
      do that, call the routines directly.
      
      Use ARCH_HAVE_EXTRA_ELF_NOTES as the only flag, and based on it decide
      whether we want the extern declarations or the empty versions.
      
      Since we have empty routines, actually use them in the coredump code to
      save a few #ifdefs.
      
      We want to change the handling of foffset so that the write routine updates
      foffset as it goes, instead of using file->f_pos (so that writing to a pipe
      works).  So pass foffset to the write routine, and for now just set it to
      file->f_pos at the end of writing.
      
      It should also be possible for the write routine to fail, so change it to
      return int and treat a non-zero return as failure.

      [PATCH] i386: Relocate VDSO ELF headers to match mapped location with COMPAT_VDSO · d4f7a2c1
      Jeremy Fitzhardinge authored
      Some versions of libc can't deal with a VDSO which doesn't have its
      ELF headers matching its mapped address.  COMPAT_VDSO maps the VDSO at
      a specific system-wide fixed address.  Previously this was all done at
      build time, on the grounds that the fixed VDSO address is always at
      the top of the address space.  However, a hypervisor may reserve some
      of that address space, pushing the fixmap address down.
      
      This patch does the adjustment dynamically at runtime, depending on
      the runtime location of the VDSO fixmap.
      
      [ Patch has been through several hands: Jan Beulich wrote the orignal
        version; Zach reworked it, and Jeremy converted it to relocate phdrs
        as well as sections. ]

      [POWERPC] coredump: Add SPU elf notes to coredump. · bf1ab978
      Dwayne Grant McConnell authored
      This patch adds SPU elf notes to the coredump. It creates a separate note
      for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1,
      /signal1_type, /signal2, /signal2_type, /event_mask, /event_status,
      /mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id.
      
      A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to
      specify they have extra elf core notes.
      
      A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the
      additional notes could be calculated and added to the notes phdr entry.
      
      A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes
      would be written after the existing notes.
      
      The SPU coredump code resides in spufs. Stub functions are provided in the
      kernel which are hooked into the spufs code which does the actual work via
      register_arch_coredump_calls().
      
      A new set of __spufs_<file>_read/get() functions was provided to allow the
      coredump code to read from the spufs files without having to lock the
      SPU context for each file read from.

      [PATCH] auxiliary vector cleanups · 36d57ac4
      H. J. Lu authored
      The size of auxiliary vector is fixed at 42 in linux/sched.h.  But it isn't
      very obvious when looking at linux/elf.h.  This patch adds AT_VECTOR_SIZE
      so that we can change it if necessary when a new vector is added.
      
      Because of include file ordering problems, doing this necessitated the
      extraction of the AT_* symbols into a standalone header file.

      Linus Torvalds authored
      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!
