Joachim Fenkes 1457edc72d IB/ehca: Return correct number of SGEs for SRQ
Firmware would round up the number of SGEs to four, because the WQE
structure holds four SGEs. For SRQ, only three are supported, so return
a fixed value instead.

Joachim Fenkes b1812582ba IB/ehca: Fix static rate if path faster than link
The formula would yield -1 if the path is faster than the link, which
is wrong in a bad way (max throttling).  Clamp to 0, which is the
correct value.

Joachim Fenkes 51aaa54eb9 IB/ehca: Fix static rate calculation
The IPD (inter-packet delay) formula was a little off and assumed a
fixed physical link rate; fix the formula and query the actual
physical link rate, now that we can get it.  Also, refactor the
calculation into a common function ehca_calc_ipd() and use that
instead of duplicating code.

Roland Dreier 76dea3bc26 IB/ehca: Fix clipping of device limits to INT_MAX
Doing min_t(int, foo, INT_MAX) doesn't work correctly, because if foo
is bigger than INT_MAX, then when treated as a signed integer, it will
become negative and hence such an expression is just an elaborate NOP.

Fix such cases in ehca to do min_t(unsigned, foo, INT_MAX) instead.
This fixes negative reported values for max_cqe, max_pd and max_ah:

Before:

        max_cqe:                        -64
        max_pd:                         -1
        max_ah:                         -1

After:
        max_cqe:                        2147483647
        max_pd:                         2147483647
        max_ah:                         2147483647

Based on a bug report and fix from Anton Blanchard <anton@samba.org>.

* Mark the notifier_block (and callback function, and another static
