i have tried with vanilla 2.6.11.6 now and compiling for ppc604 still
fails with the errors you described. they go away with your suggested
fixes (only had to modify the linenumbers, diff attached, apply with -p0)

oh, not that the kernel compiles now - it seems it just overcame a build
error out of many :->

now it [1] fails with:

In file included from arch/ppc/kernel/time.c:68:
include/asm/time.h:61: warning: type qualifiers ignored on function return
type
arch/ppc/kernel/time.c:92: error: static declaration of 'time_offset'
follows non-static declaration
include/linux/timex.h:236: error: previous declaration of 'time_offset'
was here
make[1]: *** [arch/ppc/kernel/time.o] Error 1
make: *** [arch/ppc/kernel] Error 2

thank you,
Christian.
