+Subject: 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.
