The official reason is "with the presence of pid namespaces in the
kernel using pid_t-s inside one is no longer safe."
But the reason I fix this right now is the following:
About a month ago (when 2.6.25 was not yet released) there still was a
one last caller of a to-be-deprecated-soon function find_pid() - the
kill_proc() function, which in turn was only used by nfs callback
code.
During the last merge window, this last caller was finally eliminated
by some NFS patch(es) and I was about to finally kill this kill_proc()
and find_pid(), but found, that I was late and the kill_proc is now
called from the ipath driver since commit 58411d1c ("IB/ipath: Head of
Line blocking vs forward progress of user apps").
So here's a patch that fixes this code to use struct pid * and (!)
the kill_pid routine.

otherwise, we get "too many retries".

The send DMA hardware queue voided a number of prior assumptions about
when a send is complete which led to completions being generated out of
order. There were also a number of locking issues when switching the QP
to the error or reset states, and we implement the IB_QPS_SQD state.

When errors are detected in RC, the QP should transition to the
IB_QPS_ERR state, not the IB_QPS_SQE state. Also, when the error is on
the responder side, the receive work completion error was incorrect
(remote vs. local).

Fix some bugs with the max_aggr module parameter added with LRO support:
- The module parameter value ignored and not actually used to set
lro_mgr.max_aggr.
- MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't
end up describing the actual module parameter.
- The nes_lro_max_aggr variable was declared as unsigned, but the
module_param line said "int" instead of "uint" for the type.
- The default value for the parameter was stuck in the permissions
field of module_param, which led to nonsensical permissions for the
file under /sys/module/iw_nes/param.
- The parameter was used in only one file but defined in another, which
led to the variable being global for no good reason. Move everything
related to the parameter to the file nes_hw.c where it is actually
used.

Because it's not correct with a non-preemptable BKL and just causes
PREEMPT kernels to have longer latencies than non-PREEMPT ones (which is
obviously not the point of it at all).
Of course, that config option actually got removed as an option earlier,
so for now this basically disables it entirely, but if BKL preemption is
ever resurrected it will be a meaningful optimization. And in the
meantime, it at least documents the intent of the code, while not doing
the wrong thing.

We should not go through the task pointer to get at the thread info,
since it's usually cheaper to just access the thread info directly.
So don't make the code look up 'current', when we can just use the
thread info accessor functions directly. This generally avoids one
level of indirection and tends to work better together with code that
also looks at other thread flags (eg preempt_count).

Stick with the original pattern, but make sure the 32-bit code
