Will the io.h change be submitted to Linus soon?

Will the change to io.h needed to support 2Gigs of RAM be submitted to
Linus soon? We are eager to move to 2.2 (over 150 machines), but need
to have that fix in place. To refresh your memory, the fix I am talking
about is this one (quoting a message from Leonard Zubkoff):

Using this change is the only way for me to get 2.2.0 to work with 2Gigs of
RAM correctly.
