Yes, by the time we got this all resolved, it was already rc8 and I
though 2.6.31 was right around the corner ... the issue didn't seem
severe enough to stick in so late in the cycle, so I queued the patch
for .32 with a cc to stable to get in 2.6.31.1.

The workaround of limiting possible cpus to 16 should be OK for the time
between 2.6.31 and 2.6.31.1.

 - R.

Why not merge it immediately? Dell R610s are fairly standard.

I think it's too late now post-rc9 ... it's not a regression (I think
the bug has been there since 2.6.29) and I think Linus would prefer to
minimize the # of patches that go in now.
