[PATCH 0 of 2] v2: memshare/xenpaging/xen-access fixes for xen-unstable
The following two patches allow the parallel use of memsharing, xenpaging and
xen-access by using an independent ring buffer for each feature.
Please review.
v2:
- update mem_event_check_ring arguments, check domain rather than domain_id
- check ring_full first because its value was just evaluated
- check if ring buffer is initialized before calling
mem_access_domctl/mem_paging_domctl

[PATCH 0 of 3] credit2 updates
Address some credit2 issues. This patch series, along with the recent
changes to the cpupools interface, should address some of the strange

[PATCH 0/16] lguest: introduce vcpu structure
this patch makes room for the vcpu structure in lguest, already used in
this very same way at lguest64. It's the first part of our plan to
have lguest and lguest64 unified too.
When two dogs hang out, you don't have new puppies right in the other day.
Some time has to be elapsed. They have to grow first. In this same spirit, having these
patches _do not_ mean smp guests can be launched
