    [SPARC32]: Add irqflags.h to sparc32 and use it from generic code. · e8dd1612
    Robert Reif 提交于
    Added asm-sparc/irqflags.h and moved irq related code from system.h to it.
    Renamed local_irq functions to raw_local_irq in irq.c.
    Modified system.h to include linux/irqflags.h which includes asm/irqflags.h.
    Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug.
    
    This is the first step in adding IRQ-flags state tracing as outlined in
    Documentation/irqflags-tracing.txt.  These changes should be harmless
    because they just move things around and rename them.
    
    The next step is making the lowlevel entry code modifications which
    to be honest are beyond my capabilities at this point.
    
    Boot tested on an ss20 running an SMP kernel.

	help
	  Enables the display of the minimum amount of free stack which each
	  task has ever had available in the sysrq-T and sysrq-P debug output.

	  This option will slow down process creation somewhat.
