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.
