x86: fix watchdog ops for CoreDuo
There apparently was an unnoticed conflict between an earlier patch to
this file and mine (d1e084746b), which
I noticed only now. I suppose a change like the one below (untested) is
needed; I didn't get any response on a confirmation request for this from
the submitter of the first patch.

The issue is the writing of the 'checkbit' member at the end of
setup_intel_arch_watchdog(), which my patch made go to intel_arch_wd_ops
rather than wd_ops.

x86: print message if nmi_watchdog=2 cannot be enabled
right now if there's no CPU support for nmi_watchdog=2 we'll just
refuse it silently.

print a useful warning.

x86: fix nmi_watchdog=2 on Pentium-D CPUs
implement nmi_watchdog=2 on this class of CPUs:

  cpu family      : 15
  model           : 6
  model name      : Intel(R) Pentium(R) D CPU 3.00GHz

the watchdog's ->setup() method is safe anyway, so if the CPU
cannot support it we'll bail out safely.

i386: do not BUG_ON() when MSR is unknown
Here is a small patch to change the behavior of the PMU msr allocator
to avoid BUG_ON() when the MSR is unknwon. Instead, it now returns
ok, which means "I do not manage". The current allocator is not
yet managing the full set of PMU registers (e.g., GLOBAL_* on Core 2).

[watchdog] do not BUG_ON() in the MSR allocator if MSR is unknown, return ok
instead
