* [Linux] [TPM driver] Resume frontend after checkpointingkfraser@localhost.localdomain2007-03-021-12/+16
| | | | | | | | | | | This patch implements TPM frontend driver resume after checkpointing a domain. I also now let the front-end wait for the response from the TPM until the response is there. A response must come due to the strict request/response nature of the protocol, but the time until the responses arrives depends on the type of operation that is executed by the vTPM. Resending a request is not possible with this type of device. Signed-off-by: Stefan Berger <stefanb@us.ibm.com>

* linux: allow use of split page table lockskfraser@localhost.localdomain2007-03-023-163/+9
| | | | | | | | This changes netback to use struct page's mapping field instead of the index one, and the PageForeign logic the other way around. That way, CONFIG_SPLIT_PTLOCK_CPUS doesn't have to be suppressed anymore for x86. Signed-off-by: Jan Beulich <jbeulich@novell.com>

* linux: More save/restore fixes. Fix deadlock of cpu_hotplug_lock vskfraser@localhost.localdomain2007-02-284-45/+31
| | | | | | | | | | | | | | workqueue_mutex. This is a new deadlock since the workqueue_mutex is acquired in the workqueue_cpu_calbback() function across CPU_UP_PREPARE->CPU_ONLINE. The fix is for us not to rudely grab the cpu_hotplug_lock() during save/restore -- it's really not necessary. This patch is applicable to any of our 2.6 kernels, but is absolutely required from 2.6.18 onwards. Signed-off-by: Keir Fraser <keir@xensource.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Ensure that all and only those page table entries that have their present bit set undergo p2m/m2p translation in all relevant places. This should fix migration issues with _PAGE_PROTNONE pages which previously could retain MFNs in PTEs while having the present bit clear (and thus were not getting (un)canonicalized during save/ restore).
