1. To support instantaneous report for SCSI device existing by periodic
polling
2. In arcmsr_iop_xfer(), inform AP of F/W's deadlock state to prevent
endless waiting
3. To block the coming SCSI command while the driver is handling bus reset
4. To support HW reset in bus reset error handler

This still fails to compile with SCSI_ARCMSR_AER:

  CC [M]  drivers/scsi/arcmsr/arcmsr_hba.o
drivers/scsi/arcmsr/arcmsr_hba.c:175: error: ‘arcmsr_pci_error_handlers’
undeclared here (not in a function)
make[1]: *** [drivers/scsi/arcmsr/arcmsr_hba.o] Error 1
make: *** [drivers/scsi/arcmsr/arcmsr.ko] Error 2

Making the patch set bisectable means that ordered patches must compile
in the order sent in with all possible configurations.  So patch 1/4
needs to compile on its own ... patch 2/4 needs to compile with patch
1/4 applied and so on.
