[PATCH] remove bogus #ifdef CONFIG_TRACE_IRQFLAGS_SUPPORT for debug_kmap_atomic()
in [Kernel]

From: Akinobu Mita on 12 May 2010 09:00 In f4112de6b679d84bd9b9681c7504be7bdfb7c7d5 I said that debug_kmap_atomic() needs CONFIG_TRACE_IRQFLAGS_SUPPORT. It was wrong. (I thought irqs_disabled() is only available when the architecture has CONFIG_TRACE_IRQFLAGS_SUPPORT) Remove the #ifdef CONFIG_TRACE_IRQFLAGS_SUPPORT check to enable kmap_atomic() debugging for the architectures which do not have CONFIG_TRACE_IRQFLAGS_SUPPORT.
