[Users] Trouble compiling OFED 3.12 and 3.18 on RHEL7.1/ CentOS 7.1

[Heinecke, Alexander]

Hi,

I'm having troubles installing OFED 3.12 or 3.18 on RHEL7.1/CentOS7.1. Can somebody provides hints how I can compile on this platform:

Linux 3.10.0-229.1.2.el7.x86_64 #1 SMP Fri Mar 27 03:04:26 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

With the latest nightly (3.18, daily from 5/5/15) build I'm getting (under RHEL 7.1 latest update):
                 from <command-line>:0:

  ret = mthca_MAP_ICM_page(dev, sg_dma_address(&chunk->page_list[0]),

And with 3.12-1 stable:
make[1]: Entering directory `/usr/src/kernels/3.10.0-229.1.2.el7.x86_64'

                 from <command-line>:0:

include/linux/netdevice.h:504:2: error: implicit declaration of function 'smp_mb__before_clear_bit' [-Werror=implicit-function-declaration]
  smp_mb__before_clear_bit();


In both cases the abort happens when building the compat-rdma module.

I'm compiling with -with-xeon-phi, option, but even without this option I'm  running into this issue.

Many thanks for your help!
