Ingo, please pull the latest master git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/glommer/linux-2.6-x86-integration.git master
into your tree
It is based on your tip/master branch.
This addresses the issues you raise in the last trial. In particular, I have a commit in the end
that moves even comments and blank lines from time_32.c to time_64.c, making the files exactly equal
prior to the merge.
I also found a bug in earlier series, (it's always good when it's found in-house first, so good news!).
This one should be good.
Thanks!
Glauber

thanks, i've pulled it and rebased it to -git - as that's the best base
this early in the cycle. I've pushed out the result into tip/x86/time -
havent integrated it into tip/master yet.

have just tried a test-merge, and got a few crashes during -tip testing.
One is a hard lockup during bootup, with this config:
http://redhat.com/~mingo/misc/config-Sat_Aug_16_16_49_05_CEST_2008.bad
no console output. I've pushed out this integrated tree into
tip/x86/time.broken: note that i had to do a few manual merges due to
the io_apic.c unification - maybe that interacted.
there's a 32-bit failure as well:
http://redhat.com/~mingo/misc/config-Sat_Aug_16_15_51_57_CEST_2008.bad
i dont know anything about that, other that it didnt boot up after
x86/time integration.
