Subject: [PATCH 0/5] MIPS: Fix kernel in XKPHYS

Hi all,

This series fixes support for loading kernel to XKPHYS space.
It is derived from "MIPS: use virtual addresses from xkphys for MIPS64" [1].

Boot tested on boston and QEMU with loading address set to 0xa800000090000000.
QEMU patch on the way.

Gregory and Vladimir, do let me know if I missed anything.

Thanks
- Jiaxun
