Fix memory region permission problems:
- remove useless and redundant iwch_mem_perms enum.
- create ib_to_tpt_access_rights() for mapping ib access rights
to T3 TPT permissions.
- create ib_to_mwbind_access_rights() for mapping ib access rights
to T3 MWBIND WR permissions.
- fix up the mem reg code to utilize the new functions.

This patch fixes two issues reported by Roland Dreier and Christoph Hellwig:
- Mismatched sync/locking between completion handler and destroy cq We
introduced a counter nr_events per cq to track number of irq events
seen. This counter is incremented when an event queue entry is seen
and decremented after completion handler has been called regardless
if scaling code is active or not. Note that nr_callbacks tracks
number of events assigned to a cpu and both counters can potentially
diverge.
The sync between running completion handler and destroy cq is done
by using the global spin lock ehca_cq_idr_lock.
- Replace yield by wait_event on the counter above to become zero.

There was OpenVZ specific bug rendering some cpufreq drivers unusable on SMP.
In short, when cpufreq code thinks it confined itself to needed cpu by means
of set_cpus_allowed() to execute rdmsr, some "virtual cpu" feature can migrate
process to anywhere. This triggers bugons and does wrong things in general.
This got fixed by introducing rdmsr_on_cpu and wrmsr_on_cpu executing rdmsr
and wrmsr on given physical cpu by means of smp_call_function_single().
Dave Jones mentioned cpufreq might be not only user of rdmsr_on_cpu() and
wrmsr_on_cpu(), so I'm putting them into arch/{i386,x86_64}/lib/ .

TEXT_OFFSET
aware
Since TEXT_OFFSET is meant to determine RAM location for kernel use,
itshould affect .data and .bss initial mapping in the XIP case.
Otherwise a XIP kernel would crash if TEXT_OFFSET gets somewhat larger
than 2MB.
Corresponding code is also moved up a bit to be near the similar .text
mapping code making the whole a bit more straight forward to understand.

Since commit 2552fc27ff79b10b9678d92bcaef21df38bb7bb6 XIP kernels failed
to boot because (_end - PAGE_OFFSET - 1) is much smaller than the size
of the kernel text and data in the XIP case, causing the kernel not to
be entirely mapped.
Even in the non-XIP case, the use of (_end - PAGE_OFFSET - 1) is wrong
because it produces a too large value if TEXT_OFFSET is larger than 1MB.
Finally the original code was performing one loop too many.
Let's break the loop when the section pointer has passed the last byte
of the kernel instead.

If path_rec_completion() is passed a non-NULL path record pointer
along with an unsuccessful status value, the tracing code incorrectly
prints the (invalid) DLID from the path record rather than the more
interesting status code. The actual logic of the function correctly
uses the path record only if the status indicates a successful lookup.

If no matching PD is found in ib_uverbs_reg_mr(), then the function
jumps to err_release without setting the return value ret. This means
that ret will hold the return value of the call to ib_umem_get() a few
lines earlier; if the function reaches the point where it looks for
the PD, we know that ib_umem_get() must have returned 0, so
ib_uverbs_reg_mr() ends up return 0 for a bad PD ID. Fix this by
setting ret to -EINVAL before jumping to the exit path when no PD is
found.

Jeremy Fitzhardinge suggested the use of -freg-struct-return, which does
structure-returns (such as when using pte_t) in registers instead of on
the stack.
that is indeed so, and this option reduced the kernel size a bit:
text data bss dec hex filename
4799506 543456 3760128 9103090 8ae6f2 vmlinux.before
4798117 543456 3760128 9101701 8ae185 vmlinux.after
the resulting kernel booted fine on my testbox. Lets go for it.
