Vlad,
In the process of testing qib build on RHEL7.1, we needed to fix some
underlying compat issues.
Once compat builds, qib appears to build without issue on these kernels:
RHEL7 kernel: 3.10.0-123.el7.x86_64
RHEL7.1 kernel: 3.10.0-229.el7.x86_64 (RC 2)
These fixes are:
1. Fix a warning introduced by prior work.
2. Added conditionally defined smp_mb__before_clear_bit(). RHEL7.1
<asm/bitops.h> no longer provides the define in all cases.
3. Detect reinit_completion(). RHEL7.1 now defines this in its native headers.
I realize that #2 and #3 might have already been done by someone else.
The <asm/bitops.h> work in compat really needs some more attention.
I suspect that the compat version of <asm/bitops.h> really should be
<linux/bitops.h> with autoconf driven ifdefs or other ifdefs for the macros.
Please pull from these fixes from ~mmarciniszyn/scm/new_ofed/compat from the
for-ofed-3.18 branch:

compat: determine if reinit_completion() is present
Use HAVE_REINIT_COMPLETION to avoid duplicate definition.

commit 0689335320e4aab4b5fe949143e103688c901c03

compat: add smp_mb__before_clear_bit as necessary
RHEL7.1 no longer has the above macro in <asm/bitops.h>.
Add it in the compat version of <linux/bitops> as if
<asm/bitops.h> had provided it.
This really include probably needs to be reworked using
the autoconf stuff.

introduced a build warning because of a spelling error.
