the macro SP is too common to make conflict with others, so recommend
to use another more readable and non-conflict macro SG_POOL instead of
(and recommend others do not use SP either).
The related warning (with allmodconfig for hexagon):
CC [M] drivers/scsi/scsi_lib.o
drivers/scsi/scsi_lib.c:46:0: warning: "SP" redefined [enabled by default]
arch/hexagon/include/uapi/asm/registers.h:9:0: note: this is the location of the previous definition
