From 5d70a59637911e84687b421afeb4c111a579fb2b Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 4 Mar 2014 11:17:50 +0100 Subject: ipc/compat: convert to COMPAT_SYSCALL_DEFINE Convert all compat system call functions where all parameter types have a size of four or less than four bytes, or are pointer types to COMPAT_SYSCALL_DEFINE. The implicit casts within COMPAT_SYSCALL_DEFINE will perform proper zero and sign extension to 64 bit of all parameters if needed.
