I did (assuming you're referring to the shared page table discussion;
see
http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&threadm=E1844h3-0002Bt-00%40w-gerrit2&rnum=4&prev=/groups%3Fq%3Dben%2Blahaise%26hl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8%26scoring%3Dd%26selm%3DE1844h3-0002Bt-00%2540w-gerrit2%26rnum%3D4).

There is nothing new there.  Now if you'd read the original
discussion, you'd see that Linus considered those objections and still
preferred separate system calls.  You have to realize that the huge
page syscalls are NOT a replacement for transparent superpages.  They
serve a different purpose and have a different scope (we're talking
about pages of the size of 256MB and more, not merely something that's
a small multiple of the base page size).

Please apply the patch.
