[Xen-devel] [PATCH v2 0/3] Improvements to allow refcoutning of DOMCTL_{, un}pausedomain

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

The first patch has no functional change, but introduces a common atomic.h

The second patch introduces new common atomic_t manipulation function

The third patch uses these new common functions as a basis for fixing the
DOMCTL_{,un}pausedomain reference counting issues.

This has been functionally tested on x86, and compile tested on both flavours
of ARM.

Andrew Cooper (3):
  xen/atomic: Introduce common atomic header and update includes
  xen/atomic: Implement atomic_{inc,dec}_bounded()
  xen/common: Properly reference count DOMCTL_{,un}pausedomain
