Subject: [GIT PULL] allocator argument fixes for v4.19-rc8

Hi Greg,

Please pull this fix for open-coded multiplication in allocator arguments
for v4.19-rc8. This has been in linux-next for almost a week with no
reported issues. As discussed last week[1] this catches 4.19 up to
the same level of coverage we had in 4.18 for avoiding these kinds of
unchecked multiplications.

Thanks!

-Kees
