From 46e12c07b3b9603c60fc1d421ff18618241cb081 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Sat, 14 Jul 2012 09:22:05 +0200 Subject: MIPS: O32 / 32-bit: Always copy 4 stack arguments. This gets us rid of the hard to maintain table of the number of syscall arguments and paves the way for further restructuring of the syscall code.
