Christian Limpach f67b5ead29 [xenstored] Fix error path when xc_map_foreign_range fails. 
If xc_map_foreign_range fails, the new domain object is freed,
but it is not removed from the connection list.

kfraser@localhost.localdomain 154753acf2 hvm: Clean up console-information passing via xenstore. 
Each serial, parallel and monitor device in qemu that is connected to
a pty creates a xenstore node of the form:
 <domain-path>/monitor/tty
 <domain-path>/serial/<n>/tty
 <domain-path>/parallel/<n>/tty

In addition, serial/0 (com1) also registers its information at:
 <domain-path>/console/tty

Also fix a realloc() failure memory leak.

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.
