[Xen-devel] [RESEND PATCH v5 0/9] vcpu soft affinity for credit1 (first half only)

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

I almost kept the subject line as it was in actual v5, for making it easier to
'identify' this series. However, this is *only* a resend of the first half of
the soft affinity series, which, actually, doesn't contain any bit of the soft
affinity implementation. What's inside here is:
 - the node-wise vcpu pinning specification for xl, which was around and pretty
   much all acked for months,
 - a couple of fixes for libxl, all acked as well.

Therefore, as discussed and decided already during the actual soft affinity
series review, these patches, and only these ones, are 4.4 material.

As said, everything is Acked-by already *except* for patch 4 ("libxl: move
libxl_{cpu,node}_bitmap_alloc()"), which is only code motion and no functional
change, and which I included in this resend after explicit request of the tools
maintainers to do whatever it takes to keep motion and functional changes
separate.  Another thing is, in patch 6 ("libxc/libxl: allow to retrieve the
number of online pCPUs"), I added a comment, next to the newly introduced
function declaration, explaining that it's up to the caller to use the
information he gets correctly.

Both these things should be super-straightforward. :-)

There is a git branch from where the series can be pulled:

 git://xenbits.xen.org/people/dariof/xen.git numa/per-vcpu-affinity-v5b

Let me know if I can do anything else...

Thanks and Regards,
Dario
