Subject: um: fix call tracer and bug handler
From: Richard Weinberger <richard@xxxxxx>
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.
