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
resuming in a new domain. Likewise, only invoke frontend device resume
code when in a new domain (the resume functions all tear down the
existing function and wait for the backend to negotiate a new one,
which does not happen in the source domain).

kfraser@localhost.localdomain 6465003372 [XENFB] xenfb_update_screen() calls zap_page_range() while holding spinlock mm_lock. 
Changeset 13018:c98ca86138a7422cdf9b15d87c95619b7277bb6a merely sweeps
the bug under the carpet: it silences zap_page_range()'s cries for
help by keeping interrupts enabled.  That doesn't fix the bug, and
it's also wrong: if a critical region gets interrupted, and the
interrupt printk()s, xenfb_refresh() gets executed and promptly
deadlocks.

This patch fixes the locking, but leaves open a race between
xenfb_update_screen() and do_no_page().  See the source code for a
detailed explanation of how it works, and where it fails.

kfraser@localhost.localdomain f665678307 [LINUX] Properly trigger XenbusStateClosed in blkfront 
In some situations, like when error happens in block attach for
a guest in dom0, backend send us XenbusStateClosing notification.
However, as frontend were never properly initialized, it fails
to change its own state to XenbusStateClosed, leaving the system
in a dead-end state.
