Hello Michael,

This patch makes a whole bunch of ccflags-y += -D__CHECK_ENDIAN__ 
statements obsolete. Have you considered to remove these statements?

Additionally, there are notable exceptions to the rule that most drivers 
are endian-clean, e.g. drivers/scsi/qla2xxx. I would appreciate it if it 
would remain possible to check such drivers with sparse without enabling 
endianness checks. Have you considered to change #ifdef __CHECK_ENDIAN__ 
into e.g. #ifndef __DONT_CHECK_ENDIAN__?

Thanks,

Bart.
