would currently generate a segfault.

suspend, and push the printf("suspend") out of xc_linux_save and into xc_save.
This means that xc_linux_save can be used without the xc_save wrapper if
desired.

x86/32 map_domain_page() mapcache now being per-domain
rather than global.
Other cleanups include removal of static definition of
CPU0's idle domain. Instead a single, multi-cpu, idle domain
is dynamically created early during bootstrap.

then check curr_vcpu all with interrupts disabled. This in
turn requires us to hoist the heck of next's vcpu_dirty_cpumask
as sending the flush IPI needs us to have interrupts enabled to
avoid deadlock.

amount of time of the one after xm block-detach) between attach and
detach operations, giving attach enough time to complete, making test 06
suceed.

Add a new per-vcpu dirty cpumask (vcpu_dirty_cpumask), useful for
state flushing and selective tlb flushing.

leading to ill messages when X starts up (and potentially to other
problems). The attached patch fixes that. However, it also points out
that there is a potential disagreement between the dom0_ops interface
and the internal MTRR interface - the former expects an unsigned
register number from the domain, the latter wants a signed one and does
a lookup when it's negative. I would think that the lookup code should
just be ripped out of xen/arch/x86/mtrr/main.c.

But log's error message differs from other 3 command's error messages,
when parameter is given.
# xm log 1
Error: 'xm log' requires 0 argument.
log Print the xend log
Other 3 commands ignore parameter.
I think it might be better symmetricalize.
