thread, it must not be used in code that can be called in the context
switch path (otherwise the 32-bitness of the outgoing task is used
here rather then the 32-bitness of the incoming one, possibly
resulting in large parts of the page tables not getting converted to
read-only).

In particular, MSRs that domain0 may write to must now
be 'white listed': default policy is to ignore the write.
This will prevent SYSCALL/SYSENTER instructions from
crashign Xen, by preventing the target MSRs from being
overwritten by domain 0.

It saves very little space, no distro will disable it
in their unified build, and it's rather a pain to
implement it properly.
I've left the PRIVILEGED_GUEST option for now, as it
provides some indication of where our platform-bringup
hacks are in our Linux tree. We may wish to exclude
those from upstream merge in the first instance.

tables; the guests think they are using 2-level page tables.

This should not break SVM, however the SVM code will need some small

Revert several files that were accidentally reverted by the merge-ups
(that weren't fixed by cset 8743). Those are included here with the
2.6.15 patch re-applied as well as changes between 2.6.15 and 2.6.16-rc2.
Specifically, these are pal.h, processor.h and system.h.
This patch also reverts changes to include/asm-ia64/hypercall.h and
hypervisor.h from cset 8742.

reusing the 1:1 page table built by the builder, and it also establishes
the 1:1 direct mapping at runtime a la shadow page tables. Since the
builder constructs the full 1:1 direct mapping (but <4GB), the current
implementation wastes memory but cannot support guests with >=4GB
memory (even for x64-64).
This is also required for HVM support on the PAE host. That patch
should be sent soon.
For SVM, I think the svm code needs changes. Please look at the changes
to vmx.c and vmcs.c; should be straightforward.

able to detect the reason why a frontend is created, which can be either
due to domain creation or a restore. The attached patch now puts this
functionality into XenD and allows driver implementations in Xend to
read the state and see whether a domain is currently being resumed or
created and write this value into the xenstore for hotplug scripts to
read it. The state of a domain being resumed is set when a
XendDomainInfo object is created and reset at the end of the restore
function.
