I had made the following draft, which contains some additional info to which
you should send your upstream request (it's a bit more then Ben suggested):

The 4 slot limit was specified in 5ace60859e84113b7a185c117fbf2c429d381b59
(upstream commit ID) and the secondary commit message had this:
"Start with just DDR2, DDR3 and DDR4 on x86 for now, and only for systems with
no more than 4 memory slots. These limitations may be lifted later."
This is an upstream issue and a change to '8' should be discussed there.
~/dev/kernel.org/linux$ ./scripts/get_maintainer.pl drivers/i2c/i2c-smbus.c
Wolfram Sang <wsa@kernel.org> (maintainer:I2C SUBSYSTEM)
linux-i2c@vger.kernel.org (open list:I2C SUBSYSTEM)
linux-kernel@vger.kernel.org (open list)
So I'd suggest to send it to linux-i2c@vger.kernel.org and add the other
2 addresses in the CC and also add "Jean Delvare <jdelvare@suse.de>" to the
TO or CC as that was the original author of the aforementioned commit.
Could you 'forward' your issue there and if/when done so, notify the BTS of
where that has taken place? Then we can follow its progress as well.
