hm, how did that happen.  I had some issues with cpu_has_pse a number
of days ago but they later went away.

In my current tree I have, in arch/x86/include/asm/hugetlb.h:

#define hugepages_supported() boot_cpu_has(X86_FEATURE_PSE)

and that came in from linux-next.patch.  I wonder why your tree is
different.

<looks>

OK, http://ozlabs.org/~akpm/mmots/broken-out/linux-next.patch has no
changes to arch/x86/include/asm/hugetlb.h at all.  Maybe I fat-fingered
something.  Odd.

I have just uploaded a new snapshot - it should be good now.  Sorry about
that.
