The old 1542 scsi driver is both ISA and MCA.  The MCA portions are 
disabled when !CONFIG_MCA through the typical wrapper scheme (a la pci.h 
and !CONFIG_PCI).  However...  the driver unconditionally includes 
linux/mca.h which in turn unconditionally includes asm/mca.h.

This breaks drivers on platforms with ISA but not MCA, like alpha.

(and I suppose any PCI platform, since you could have one on an ISA bridge)
