[PATCH 0/2] Make arm64 headers self-contained

[Marc Zyngier]

Wookey recently reported that the arm64 headers are not
self-contained, making it impossible to build external kernel modules
using DKMS and a distribution kernel-headers package. I do not condone
the use of out of tree modules, but there is no reason to be more
awkward than strictly necessary, and having standalone headers seems
to be a reasonable requirement.

The offenders are asm/opcodes.h, which drags its 32bit counterpart
despite only requiring a handful of macros, and a bunch of Xen files
that directly include their 32bit equivalent.

This series solves the issue in two ways:

- asm/opcodes.h is killed, and the few required macros moved added at
  the required locations

- asm/xen/* are brutally copied oved. It'd be better if they were
  placed in a common location (include/xen/ ?), but at least that
  solves it for now

Patches on top of -rc6.
