From 1d3e2d79a7d5ab56b382ea96b64c4daa9d6f0ce4 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Sun, 28 Jul 2013 21:20:25 +0100 Subject: [PATCH] MIPS: uapi/asm/siginfo.h: Fix GCC 4.1.2 compilation It wasn't until GCC 4.3 I believe that the __SIZEOF_*__ predefined macros were added. The change below switches to the _MIPS_SZLONG macro so that compilation with e.g. GCC 4.1.2 succeeds. This is a user API header so I think this is even more important, for older userland support. The change adds an unsuccessful default too, to catch any compiler configuration oddities. Signed-off-by: Maciej W.
