Hi,
With the success of last year's Virtualization micro-conference track
at Linux Plumbers 2010, I have accepted to organize a similar track
for Linux Plumbers 2011 in Santa Rosa. Please see the official Linux
Plumbers 2011 website for full details about the conference:
Hi,
There has been some confusion around the format of the tracks at Linux
Plumbers: Presentations vs Micro Conference, so the program committee
has extended the deadline by one week. If you didn't get your submission
in earlier, or you were confused, this is your final chance.
Please see
re-submit it. I apologize for this confusion!
Hope to see plenty of proposals showing up before the deadling on the 19th!
Best regards,
Jes

Hi Isaku,
I am missing some of the patches in this series for some reason.
However, I'd like to open the discussion and ask why you are
Make NR_IRQ overridable by each pv instances.
Pv instance may need each own number of irqs so that
NR_IRQS should be the maximum number of nr_irqs each
pv instances need.
This really looks dodgy.

Our justification is as follows.
The difference is its scope. pv_ops for virtualization and
machine vector is for platform difference.
- pv_ops does cover the area which shouldn't belong to machine vector.
For example, ia64 intrinsics paravirtualization.

Rather than making these binary patches, why not make them fast

I don't mind how many interfaces there are, so long as there only needs

Mmmm, last time I looked, x86 didn't scale to any interesting number

Hi Xiantao,
I general I think the code in this patch is fine. I have a couple of
nit-picking comments:
+ if (target_mask0x1) {
The formatting here isn't quite what most of the kernel does. It would
be better if you added spaces so it's a little easier to read, ie:
if (target_mask
