H A D | compat.h | 8f2df5d3 Fri Jun 20 12:17:29 CDT 2014 Lijun Pan <LIJUN.PAN@FREESCALE.COM> linux/compat.h: port lower_32_bits and upper_32_bits from Linux [backport from linux commit 204b885e and 218e180e7] 64 bit processors are becomming more and more popular. lower_32_bits and upper_32_bits save our labor doing shifts/manipulations like (u32)(n) and (u32)((n) >> 32). They are good helpers in both little and big endian cases. Port these two functions here from Linux:include/linux/kernel.h, cater the comment message to little/big endian cases. Later on, developers could include linux/compat.h if they want to use these two functions. Signed-off-by: Lijun Pan <Lijun.Pan@freescale.com>
