      It seems that tty was already free in disassocate_ctty when it tries
      to dereference tty->driver.
      
      After moving the lock_kernel before the mutex_unlock, I can no longer
      reproduce the problem.
      
      [ This is a temporary partial fix for the documented and long standing
        race in disassociate_tty.  This stops most problem cases for now.
      
        For the next release the -next tree has an initial implementation of
        kref counting for tty structures and this quickfix will be dropped.

      Revert "fbcon: bgcolor fix" · 3838f59f
      Linus Torvalds authored
      This reverts commit 2d04a4a7, which made
      it impossible to make the softcursor use the highlight colors.
      
      Yes, the fourth bit should be "blinking", but since we cannot reasonably
      blink in fbcon, highlighting it with a bright background is preferable.

      powerpc: Do not ignore arch/powerpc/include · 0afd2ac9
      Junio C Hamano authored
      Back when .gitignore file was added to arch/powerpc/ in 06f2138e ([POWERPC]
      Add files build to .gitignore, 2006-11-26), there indeed was nothing
      tracked in the ignored hierarchy and ignoring everything made sense.  But
      we have very many tracked files there these days, and having a higher
      level .gitignore that ignores everything is asking for future troubles..
      
      This should have been part of b8b572e1 (powerpc: Move include files to
      arch/powerpc/include/asm, 2008-08-01).

      powerpc/mm: Fix attribute confusion with htab_bolt_mapping() · bc033b63
      Benjamin Herrenschmidt authored
      The function htab_bolt_mapping() is used to create permanent
      mappings in the MMU hash table, for example, in order to create
      the linear mapping of vmemmap.  It's also used by early boot
      ioremap (before mem_init_done).
      
      However, the way ioremap uses it is incorrect as it passes it the
      protection flags in the "linux PTE" form while htab_bolt_mapping()
      expects them in the hash table format.  This is made more confusing by
      the fact that some of those flags are actually in the same position in
      both cases.
      
      This fixes it all by making htab_bolt_mapping() take normal linux
      protection flags instead, and use a little helper to convert them to
      htab flags. Callers can now use the usual PAGE_* definitions safely.

      powerpc/pci: Don't keep ISA memory hole resources in the tree · 8db13a0e
      Benjamin Herrenschmidt authored
      When we have an ISA memory hole (ie, a PCI window that allows us to
      generate PCI memory cycles at low PCI address) mixed with other
      resources using a different CPU <=> PCI mapping, we must not keep
      the ISA hole in the bridge resource list.
      
      If we do, things might start trying to allocate device resources
      in there and will get the PCI addresses wrong.
      
      This fixes it by arranging to remove the ISA memory hole resource in
      this case.  This fixes various cases of PCMCIA breakage on PowerBooks
      using the MPC106 "grackle" bridge.

      powerpc: Zero fill the return values of rtas argument buffer · b79998fc
      Nathan Fontenot authored
      The kernel copy of the rtas args struct contains the return
      value(s) for the specified rtas call.  These are copied back
      to user space with the assumption that every value has been
      set by the rtas call, which turns out to be not always true.
      Thus userspace can see random values and think the call failed
      when in fact it succeeded, but for some reason didn't set one
      of the return values.
      
      This fixes the problem by zeroing out the return value fields
      of the rtas args struct before processing the rtas call.
