This patchset fixes a couple of issues encountered in the suspend/resume code
base. First when using the kernel device tree update code update-nodes is
unnecessarily called more than once. Second the cpu cache lists are not
updated after a suspend/resume which under certain conditions may cause a
panic. Finally, since the cache list fix utilzes in kernel device tree update
code a means for telling drmgr not to perform a device tree update from
userspace is required.

Changes from v2:
- Moved dynamic configuration update code into pseries specific routine
  per Nathan's suggestion.

Changes from v1:
- Fixed several commit message typos
- Fixed authorship of first two patches

Haren Myneni (2):

    operation
