From 4d7b92ad572b4bd4d92fc80911641bb6cba3b99c Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Fri, 2 Jan 2009 19:32:59 -0800 Subject: sparc: add '32' suffix to reg_window, sigcontext, __siginfo_t Renaming a few types to contain a 32 suffix makes the type names compatible with sparc64 and thus makes sharing between the two a lot easier. Note: None of these definitions are expected part of the stable ABI towards userspace. Signed-off-by: Sam Ravnborg Signed-off-by: David S.
