Looks to me that issue was introduced by:
commit 1df0888f6a736e1612ce8b054d6c17651ebd003f

Remove most checks of __BYTE_ORDER
For a long time now endian.h has defined sane fixed with conversion
macros, so lets just use them instead of rolling our own.
Also, htonll is defined in this source tree under infiniband/arch.h,
so all users of that macro can just use the header.
Someday we should also get rid of all the endless wrappers..

where byte order macros are from libibverbs arch.h which also includes
the memory barrier stuff.
So can't arch.h be separated out into 2 headers and have the various
parts of rdma-core include one or both of these headers as needed ?
