I'm getting compile failures building this driver, which I narrowed
down to the ilog2 call in ehca_get_max_hwpage_size...
ERROR: ".____ilog2_NaN" [drivers/infiniband/hw/ehca/ib_ehca.ko]
undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
The use of shca->hca_cap_mr_pgsize is confusing the compiler, and
resulting in the __builtin_constant_p in ilog2 going insane.
I tried making it take the u32 pgsize as an argument and the expansion
of shca->_pgsize in the caller, but that failed as well.
With this patch in place, the driver compiles on my GCC 4.6.2 here.
