It wouldn't hurt to try and improve things, but I don't see anything
really scary here...

This one seems pretty bad -- I guess it's -funit-at-a-time going
beserk. Are you building for x86_64? What compiler version?
With
$ gcc --version
gcc (GCC) 4.0.2 (Debian 4.0.2-2)
I get something slightly different:
0x000005a0 mthca_init_hca: 568
is the top offender, and
0x0000e9a0 mthca_process_mad: 168
is the second-biggest function.
In any case it might be worth dynamically allocating some of the large
structures used in the init path, just to be safe.
