* Hypercall calling convention:
*
* Each hypercall may have 0-6 parameters.
*
* 64-bit hypercall index is in RAX, goes from 0 to __NR_hypercalls-1
*
* 64-bit parameters 1-6 are in the standard gcc x86_64 calling convention
* order: RDI, RSI, RDX, RCX, R8, R9.
*
* 32-bit index is EBX, parameters are: EAX, ECX, EDX, ESI, EDI, EBP.
* (the first 3 are according to the gcc regparm calling convention)
*
* No registers are clobbered by the hypercall, except that the
* return value is in RAX.
