The entries in static struct mem_type mem_types[] look entirely
different to me. What am I missing?

BTW I'm using dtc.git 4e76ec796c90d44d417f82d9db2d67cfe575f8ed and not
the kernel copy.
dtc-lexer.l in my HEAD is identical to the current master

This affects arch/powerpc/boot/dts/virtex440-ml510.dts but I think it is
actually a more general issue:
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux- virtex440-ml510.dtb
CC scripts/mod/devicetable-offsets.s
GEN scripts/mod/devicetable-offsets.h
HO
1
make: *** [b4qds.dtb] Error 2
I spotted in build tests of device-tree.git, announcement
https://lkml.org/lkml/2013/4/24/209, which builds *.dts. Probably no one would
do this this in real life on linux.git but it still seems worth fixing.

Various temporary files used when building DTB files were not suffixed with
.tmp and therefore were not cleaned up by "make clean".

What about PARAVIRT_TIME_ACCOUNTING? I'm not sure what it is but it
looks like a more lightweight version of pv stolen time?
