alpha: fixes for specific machine types
Files: arch/alpha/kernel/core_mcpcia.c arch/alpha/kernel/sys_rawhide.c include/asm-alpha/core_mcpcia.h Determine correct hose configuration; RAWHIDE family can have 2 or 4 hoses, so make sure non-existent hoses are ignored. arch/alpha/kernel/err_titan.c Supply a needed #include <asm/irq_regs.h> arch/alpha/kernel/module.c Add some useful output to the relocation overflow messages. arch/alpha/kernel/sys_noritake.c Supply necessary noritake_end_irq() to correct interrupt handling. This fixes a problem first noted by hangs during boot probing with a DE500-BA TULIP NIC present. arch/alpha/kernel/sys_sio.c Correct saving of original PIRQ register (PCI IRQ routing); change default PIRQ setting to leave PCI IRQs 9 and 14 free to be used for sound (Multia) and IDE (any), respectively. include/asm-alpha/io.h Supply the "isa_virt_to_bus" routine.
