When the kernel calls into RTAS, it switches to 32-bit mode. The magic page was is longer accessible in that case, causing the patched instructions in the RTAS call wrapper to crash. This fixes it by making available a 32-bit mapping of the magic page in that case. This mapping is flushed whenever we switch the kernel back to 64-bit mode.
