The four files aha1542.h, aha1740.h, gvp11.h and mvme147.h under
drivers/scsi/ contain two-thirds of an include guard, but do not
#define the macro. Add those #defines. git grep says the macro names
are not defined elsewhere.

Two scsi-mq tips:
1. Several people have been wondering how to enable scsi-mq.
Add this to your kernel command line (e.g., in /boot/grub/grub.conf
if using grub-1):
scsi_mod.use_blk_mq=Y
One way to tell it is enabled is to notice these directories
being created in sysfs:
