 Log Message:
 Alter sparc64 bootstrap:
 
  - Map kernel with permanent 4MB pages to ease kernel's life
  - Pass mappings down to the kernel as part of bootinfo structure
  - Try to detect whether kernel is aware of the new boot scheme or not and
    in the former case map the kernel using OpenFirmware and do not pass
    bootinfo structure
  - Provide -C switch to force compatibility mode if autodetection fails
  - While on this, fix PR #25763: If load of default kernel fails, try one by
    one those specified in compiled-in list
 
 Much inspired by the bootloader of FreeBSD, with some imported code from there.
