      powerpc: Fix vio_bus_probe oops on probe error · cd5aeb9f
      Brian King authored
      
      
      When CMO is enabled and booted on a non CMO system and the VIO
      device's probe function fails, an oops can result since
      vio_cmo_bus_remove is called when it should not.  This fixes it by
      avoiding the vio_cmo_bus_remove call on platforms that don't implement
      CMO.

      powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devices · 4589f1fe
      Joachim Fenkes authored
      
      
      Recent of_platform changes made of_bus_type_init() overwrite the bus
      type's .dev_attrs list, meaning that the "name" attribute that ibmebus
      devices previously had is no longer present.  This is a user-visible
      regression which breaks the userspace eHCA support, since the eHCA
      userspace driver relies on the name attribute to check for valid
      adapters.
      
      This fixes it by providing the "name" attribute in the generic OF
      device code instead.  Tested on POWER.

      powerpc: Fix /dev/oldmem interface for kdump · 7230ced4
      Michael Ellerman authored
      A change to __ioremap() broke reading /dev/oldmem because we're no
      longer able to ioremap pfn 0 (d177c207
      
      , "[PATCH] powerpc: IOMMU: don't
      ioremap null addresses").
      
      We actually don't need to ioremap for anything that's part of the linear
      mapping, so just read it directly.
      
      Also make sure we're only reading one page or less at a time.
