From 7bb0dc2222779b4cbf1ec9ad651e500e62fa5b11 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sat, 5 Sep 2015 09:32:35 +0200 Subject: x86/headers: Unify 'struct _fpstate_ia32' and i386 struct _fpstate 'struct _fpstate_ia32' and 'struct _fpstate' on i386 are identical in all fields, except 'padding1' being named 'padding'. We unify the two structures and add a union that is both named 'padding1' and 'padding', in the (unlikely) case there's user-space code that relies on the padding field name. We rename the two main types to be: struct _fpstate_32 struct _fpstate_64 for the 32-bit and 64-bit frame, and map them to the main and compat structure names (_fpstate) depending on whether we are on 32-bit or on 64-bit kernels. We also keep the old _fpstate_ia32 name as a legacy name. Acked-by: Mikko Rapeli Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Brian Gerst Cc: Denys Vlasenko Cc: H.
