[Xen-devel] [PATCH for-4.13 v4 15/19] xen/arm: Allow insn.h to be called from assembly

[Julien Grall <julien.grall@xxxxxxx>]

A follow-up patch will require to include insn.h from assembly code. So
we need to protect any C-specific definition to avoid compilation
errors when used in assembly code.
