[Xen-devel] [PATCH 0 of 8] Xen-side netchannel2 patches, take two

[<steven.smith@xxxxxxxxxx>]

This patch series includes all of the Xen and tools bits of
netchannel2.  It's essentially similar to the one I posted on Sunday,
except:

-- I've dropped the unmodified drivers support.  It'd probably be
   fairly straightforward to re-introduce it, but it's not clear that
   anyone's actually using unmodified drivers any more (they don't
   even build against a 2.6.27 kernel, for instance).

-- I've switched to using uint64_t for page numbers in the public
   structures, because uint32_t is no longer enough now that Xen
   supports sparse physical memory.

-- The gnttab_get_status_frames structure now uses a
   GUEST_HANDLE(uint64_t) for the pointer to the status frames array,
   rather than a straight uint64_t.

The problems which these changes fix were all pointed out by Jan
Beulich (thanks!).

Most of these patches are unchanged since last time, but I'm reposting
all of them just to keep everything together.  The only one with
substantial changes is number 5:

Introduce a grant_entry_v2 structure.

There are also minor changes to the next two patches, mostly just
compensating for renamed fields in structures.



I've also fixed up the Linux patch queues to match the new interface,
but won't be posting the new queues, because they're rather large and
have no substantial changes from last time.  Instead, I've pushed the
changed queues to the git repos:

git://xenbits.xensource.com/people/ssmith/nc2-2.6.27.git branch
pq_for_merge (for the XCI 2.6.27 tree)

git://xenbits.xensource.com/people/ssmith/netchannel2-pvops.git branch
nc2/fixed_v2_grant_table_interface (for the upstream git tree)


If people would prefer I repost the whole series then I can do that as
well.


I think this should cover all of the review comments; please shout at
me if I've missed anything.

Steven.
