[Top post about patch issues.]
Looking at the patch it seems to be designed for when #else was in
use:
-#else
+#elif defined(BOOKE)
but -r308817 already has the 2nd line (BOOKE). Your patch shows:
Index: sys/powerpc/include/pmap.h
===================================================================
--- sys/powerpc/include/pmap.h (revision 308718)
+++ sys/powerpc/include/pmap.h (working copy)
So it looks like you started from before -r308817 .
Trying it (I'm at -r308860):

It looks like sys/powerpc/include/pmap.h from -r176700 from 2088-
Mar-3
is when the BOOKE/E500 split started with the preprocessor use of
AIM
and #else . This predates PowerMac G5 support.
This is definitely not new for the general structure on the powerpc
side of things. Any place that did not have the AIM vs. not status
available was subject to problems of possibly mismatched
definitions.

[Quick top post I'm afraid.]
I think that I figured out why there is a problem even earlier
--that just did not stop the compiles.
lib/libutil/kinfo_getallproc.c is built here as part of buildworld
(stage 4.2 "building libraries" instead of buildkernel. It does not
have the KERNCONF's AIM vs. BOOKE vs. . . . definitions vs. lack of
them).
So if it includes machine/pmap.h that binds to
sys/powerpc/include/pmap.h which has the structure. . .
. . .
#if defined(AIM)
. . . (definitions here)
#elif defined(BOOKE)
. . . (definitions here)
#endif
. . .
it gets no definition now.
With the older:
. . .
#if defined(AIM)
. . . (definitions here)
#else
. . . (definitions here)
#endif
. . .
It got a definition, just not necessarily the right one.

Can you try the attached patch? There was a subtle ABI issue that
r308817 exposed, which is that the pmap structs aren't identical
such
that the pm_stats are at different locations, and libkvm ends up
reading with the Book-E pmap, getting different stats than
expected for
AIM. This patch fixes that, bumping version to account for this ABI
change.
