The clockevents conversion has to be done in one go. The x86-64 clockevents patch set overall summary is: 22 files changed, 631 insertions(+), 1199 deletions(-) due to sharing the code of PIT and HPET with i386. I did not dare to tackle sharing apic.c yet, but there is definitely a chance to get this done some day when I get bored and do a: # mkdir arch/x86 :) I'm going to post the x86_64 set for review to LKML once the outstanding highres/dyntick fixups have hit mainline resp. -mm To create a highres / dyntick enabled kernel for x86_64: http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.21.tar.bz2 http://kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.21-git2.bz2 http://www.tglx.de/projects/hrtimers/2.6.21-git2-x86-64/patches-2.6.21-git2.patch.bz2 Comments, bugreports, patches are welcome as ususal Thanks, tglx - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
