IMNAL but this is just an alternative, less strict, MIT license for this
file, same as the x86 counterpart
(arch/x86/include/asm/xen/hypercall.h). The intent is to allow other
operating systems, the BSDs for example, to be able to use it if they
want to.
Actually, given that the ARM implementation is not inline, I should
remember to add this copyright header to the assembly source file too.
