It's called "kernel log buffer size" and it's in "General setup".

Did the dmesg output get you what you needed? Why the few KB
difference?

Yeah, looked at your e820 and your MTRR settings and I think my patch is
doing the right thing (i.e. trimming just the right amount of memory,
leaving you with as much as possible).
The mem= approach though looks slightly off, but I haven't looked at
x86_64's mem= handling to see why. From a high level though, adjusting
end_pfn is the right thing to do, since theoretically mem= could choose
to make holes in your low memory and keep your high memory in the
allocation pools (though it's not generally implemented this way).
