From b76cb6c869b966b4c991251136b45b3e1babc4e8 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sat, 5 Sep 2015 09:32:29 +0200 Subject: [PATCH] x86/headers: Fix (old) header file dependency bug in uapi/asm/sigcontext32.h Mikko Rapeli reported that the following standalone user-space header does not compile: #include Due to undefined 'struct __fpx_sw_bytes' which is defined in asm/sigcontext.h. The following header order works: #include #include and that's probably how everyone's been using these headers for the past decade or so, but it's a legit header file dependency bug, so include asm/sigcontext.h in sigcontext32.h to allow it to be built standlone.
