From bd8fbdee6562ee526f3c2582a3b373ef195015dd Mon Sep 17 00:00:00 2001 From: Rui Sousa Date: Wed, 3 Sep 2008 17:53:07 +0200 Subject: [PATCH] lockdep: fix compilation when CONFIG_TRACE_IRQFLAGS_SUPPORT is not set This patch fixes compilation if CONFIG_TRACE_IRQFLAGS_SUPPORT is ever disabled (which is currently not allowed by Kconfig). Alternatively we could just remove the option altogether and the associated code paths. Since the compilation error has been in the tree for at least two years and no one noticed it, I guess we don't really have the need for CONFIG_TRACE_IRQFLAGS_SUPPORT=n. Boot tested on x86 UP.
