+Subject: [PATCH 02/15] avr32: add varargs handling of prctl syscall
+
+prctl is defined to use varargs in the header file, hence it needs varargs
+specific handling in the source. This patch properly handles the variodic
+argument before the syscall is passed to the kernel for the AVR32 architecture.
