+/********************************************************************
+ * Call function in Hyp mode
+ *
+ *
+ * unsigned long kvm_call_hyp(void *hypfn, ...);
+ *
+ * This is not really a variadic function in the classic C-way and care must
+ * be taken when calling this to ensure parameters are passed in registers
+ * only, since the stack will change between the caller and the callee.
+ *
+ * Call the function with the first argument containing a pointer to the
+ * function you wish to call in Hyp mode, and subsequent arguments will be
+ * passed as r0, r1, and r2 (a maximum of 3 arguments in addition to the
+ * function pointer can be passed). The function being called must be mapped
+ * in Hyp mode (see init_hyp_mode in arch/arm/kvm/arm.c). Return values are
+ * passed in r0 (strictly 32bit).
+ *
+ * The calling convention follows the standard AAPCS:
+ * r0 - r3: caller save
+ * r12: caller save
+ * rest: callee save
