kfraser@localhost.localdomain 5ba41352cd [Linux] [TPM driver] Resume frontend after checkpointing 
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.

This changes netback to use struct page's mapping field instead of the

CONFIG_SPLIT_PTLOCK_CPUS doesn't have to be suppressed anymore for x86.

kfraser@localhost.localdomain ed372f4e41 linux: More save/restore fixes. Fix deadlock of cpu_hotplug_lock vs 
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.
