[Skiboot] [RFC PATCH 0/4] virtual memory for OPAL boot

[Nicholas Piggin]

I've made quite a few improvements and bug fixes, but not much
change in concept. This is booting pretty reliably on a P9 WSP
platform. Haven't tested P8 or other platforms, and there's a
weird checkstop with STB I haven't debugged (so just commented
out the code).

Nicholas Piggin (4):
  asm/head: move unnecessary code out of head
  core/exceptions.c: rearrange code to allow more interrupt types
  asm/head.S: set POWER9 radix HID bit at entry
  virtual memory for OPAL boot
