From 2d057c69e743bfb88f1259ddbf1b1160bdd850e5 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sat, 5 Sep 2015 09:32:37 +0200 Subject: [PATCH] x86/headers: Clean up the kernel's struct sigcontext types to be ABI-clean Use the __u16/32/64 types we standardized on in ABI definitions and which other sigcontext related types are already using. This will help unify struct sigcontext types between native 32-bit, compat and 64-bit kernels. Acked-by: Mikko Rapeli Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Brian Gerst Cc: Denys Vlasenko Cc: H.
