    x86, pci: introduce config option for pci reroute quirks (was: [PATCH 0/3] Boot IRQ quirks for Broadcom and AMD/ATI)
    
    This is against linux-2.6-tip, branch pci-ioapic-boot-irq-quirks.
    
    From: Stefan Assmann <sassmann@suse.de>
    Subject: Introduce config option for pci reroute quirks
    
    The config option X86_REROUTE_FOR_BROKEN_BOOT_IRQS is introduced to
    enable (or disable) the redirection of the interrupt handler to the boot
    interrupt line by default. Depending on the existence of interrupt
    masking / threaded interrupt handling in the kernel (vanilla, rt, ...)
    and the maturity of the rerouting patch, users can enable or disable the
    redirection by default.
    
    This means that the reroute quirk can be applied to any kernel without
    changing it.
    
    Interrupt sharing could be increased if this option is enabled. However this
    option is vital for threaded interrupt handling, as done by the RT kernel.
    It should simplify the consolidation with the RT kernel.
    
    The option can be overridden by either pci=ioapicreroute or
    pci=noioapicreroute.
