The emacs variable to set the C style from a local variable block is
c-file-style, not c-set-style.

When the subject domain is not the current one (e.g. during domctl or
HVM save/restore handling), use of gdprintk() is questionable at best,
as it won't give the intended information on what domain is affected.
Use plain printk() or dprintk() instead, but keep things (mostly) as
guest messages by using XENLOG_G_*.

In certain cases this will allow us to load old HVM save images where
an HVM saved chunk has subsequently been extended with new
fields. Rather than fail to load the chunk, we can pad the extended
structure with zeroes, if the caller knows how to handle that.

Allow HVM save/restore from different changesets of Xen. The HVM save
records are supposed to be backwards compatible; XenServer
live-migrates between versions of Xen during upgrades.

It's not a sensible thing to do, and it is easier than auditing all
state save/restore functions for safety (most importantly, racing
against domain_relinquish_resources).
Also place a spin_barrier on domain_lock after asserting d->is_dying,
allowing critical regions under the domain_lock to safely check
is_dying and avoid races with domain_relinquish_resources().

Also, disable stdvga caching on hvm save/restore, as the shadow vga
state is not preserved.

struct hvm_save_header is arch specific so that arch specific part of
hvm_save()/hvm_load() are moved into arch_hvm_save()/acrh_hvm_load()
