Patch #1 just alphabetizes the #includes to make it easier to read.
Patch #2 replaces vptr->dev with vptr->netdev, again for clarity in the code.
Patch #3 replaces the pci dma functions with the generic versions.

Looks like we can't do anything about that in the HPET code itself.
Vitaliy, could you try that patch ?
Thanks, I've tried it several days ago (and still using a patched
kernel :)) - the box survives.
But at which moment should I check for "Spurious interrupt" in dmesg?

It comes from arch//include/asm/..., with the architecture you're
Hello all,
if you look at the above file it contains:

where should this file come from? There is no "asm" directory inside
linux-3.8.8/include/ ... ?

Hello,
Unfortunately, no. Out of curiosity I've tried booting kernel
3.9-rc8 in EUFI mode but it exhibits the same problem.
Right after the boot:

In cpuset_hotplug_workfn(), partition_sched_domains() is called without
hotplug lock held, which is actually needed (stated in the function
header of partition_sched_domains()).
This patch tries to use rebuild_sched_domains() to solve the above
issue, and makes the code looks a

Hi Thierry,
I don't know this code well but the drm/drm.h has an #if def so that
either linux/types.h is included or the __[us]* types are defined in
a different way with the comment "One of the BSDs".
Also I sent a patch last year to include linux/types.h in exynos_drm.h
but it now includes
