Message-Id: <1302698512-11979-1-git-send-email-richard@nod.at> Date: Wed, 13 Apr 2011 14:41:51 +0200 From: Richard Weinberger <richard@....at> To: akpm@...ux-foundation.com Cc: slyich@...il.com, linux-kernel@...r.kernel.org, jdike@...toit.com, user-mode-linux-devel@...ts.sourceforge.net, Richard Weinberger <richard@....at> Subject: [PATCH 1/2] um: Fix call tracer and bug handler Commit 1de1502c (x86, um: now we can get rid of trivial uml headers) removed accidentally bug.h which broke UML's call tracer and bug handler. Without asm-generic/bug.h UML uses BUG() from arch/x86/ which makes use of ud2. UML cannot use ud2, it raises SIGILL in user mode. As UML has a different stack for handling signals the call trace will be cut off.
