Both your speed and your stamina are much better than mine; and your
patch belies your Sturgeon's law signature. I haven't got beyond the
architectures yet in my parallel attempt, and you do appear to be
doing everything right (but a local variable often welcome, yes).

I'm giving up for the night, will contine tomorrow.
The only discrepancy I notice so far is that I have
arch/alpha/kernel/osf_sys.c
arch/ia64/mm/hugetlbpage.c
arch/sparc/kernel/sys_sparc_32.c
in my list of changed files, but they're not in yours.
