Keir Fraser abaff6993d pciback: Devices can lose config space info on D3->D0 transition, yet 
they may not (and even if they try, can not) restore the BARs. Since
Linux does not do this for us, pciback must do it for itself manually.

Possible todo: Restore all first 64 bytes of the config space?

kfraser@localhost.localdomain e260cd0a07 The Xen console intercepts ^O and prevents it from propagating

Emacs.  This patch changes the console to pass a single ^O

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.

kfraser@localhost.localdomain 700ba2f69b linux: allow use of split page table locks 
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.

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.
