[ofa-general] ipath_kernel.h:1115: error: implicit declaration of function 'writeq' on rhel5

[Brian J. Murrell]

I'm trying to build OFED 1.3's kernel-ib for RHEL5 and getting:

The "make kernel" starts out with:

+ make kernel
Building kernel modules
Kernel version: 2.6.18-53.1.14.el5_lustre.1.6.4.55.20080409120349smp
Modules directory: //lib/modules/2.6.18-53.1.14.el5_lustre.1.6.4.55.20080409120349smp
Kernel sources: /cache/build/BUILD/lustre-kernel-2.6.18/lustre/linux
env CWD=/cache/build/BUILD/ofa_kernel-1.3 BACKPORT_INCLUDES=-I/cache/build/BUILD/ofa_kernel-1.3/kernel_addons/backport/2.6.18-EL5.1/include/ \
		make -C /cache/build/BUILD/lustre-kernel-2.6.18/lustre/linux SUBDIRS="/cache/build/BUILD/ofa_kernel-1.3" \
		V=1  \
		CONFIG_MEMTRACK= \
		CONFIG_DEBUG_INFO=y \
		CONFIG_INFINIBAND=m \

So it seems to be correctly identifying the kernel version
"2.6.18-53.1.14.el5" as RHEL5 kernel as it does set
BACKPORT_INCLUDES=-I/cache/build/BUILD/ofa_kernel-1.3/kernel_addons/backport/2.6.18-EL5.1/include/

Any ideas why there is no readq/writeq being found?

Funny enough this same build on x86_64 is successful.
