kfraser@localhost.localdomain 74bca0b6e8 linux: scan DMI early 
While shuffling quite a few things around, this gets us closer to
native, which clearly had a reason to do the DMI scan early.

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 188ac9feda linux: Support new 'fast suspend' mode which does not require us to

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.

kfraser@localhost.localdomain eee7931c83 linux/x86: Adjust and fix page table handling. 
Ensure that all and only those page table entries that have their
present bit set undergo p2m/m2p translation in all relevant places.
This should fix migration issues with _PAGE_PROTNONE pages which
previously could retain MFNs in PTEs while having the present bit
clear (and thus were not getting (un)canonicalized during save/
restore).

Many thanks to Keir Fraser for his analysis, suggestions, and
corrections.

kfraser@localhost.localdomain d32128e96e bimodal blkback: Support multiple ring protocols. 
This is needed for 32-on-64 support.  Right now there are three
protocols: native, x86_32 and x86_64.  If needed it can be extended.

Interface changes (io/blkif.h)
 * Define the x86_32 and x86_64 structs additionally to the native
   version.
 * Add helper functions to convert them requests to native.

Backend changes:
 * Look at the "protocol" name of the frontend and switch ring
   handling accordingly.  If the protocol node isn't present it
   assumes native protocol.
 * As the request struct is copied anyway before being processed (for
   security reasons) it is converted to native at that point so most
   backend code doesn't need to know what the frontend speaks.
 * In case of blktap this is completely transparent to userspace, the
   kernel/userspace ring is always native no matter what the frontend
   speaks.

Don't destroy xenstore watches on suspend, and only recreate them when

existing function and wait for the backend to negotiate a new one,
which does not happen in the source domain).

kfraser@localhost.localdomain 9f7105d6ac linux/i386: allow CONFIG_HIGHPTE on i386

entirely disallowed if people want to sacrifice performance for less
lowmem pressure.
