Hi Merav,

FYI, there are new sparse warnings show up in

Thanks. Before submitting I run sparse and it didn't catch these issues, but apparently it didn't function well. I will submit a patch soon. Merav

The kernel doesn't enable byte-order type checks by default; you have to add CHECKFLAGS=-D__CHECK_ENDIAN__ to the make command line.
