9832a24d27 In the syncer, drop the sync mutex while patting the watchdog.
Some watchdog drivers (like ipmi) need to sleep while patting the watchdog.
See sys/dev/ipmi/ipmi.c:ipmi_wd_event(), which calls malloc(M_WAITOK).

fbce0221eb zfsvfs_create(): Refuse to mount datasets whose names are too long.
This is checked for in the zfs_snapshot_004_neg STF/ATF test (currently
still in projects/zfsd rather than head).

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zfs_vfsops.c:
- zfsvfs_create(): Check whether the objset name fits into
  statfs.f_mntfromname, and return ENAMETOOLONG if not.  Although
  the filesystem can be unmounted via the umount(8) command, any
  interface that relies on iterating on statfs (e.g. libzfs) will
  fail to find the filesystem by its objset name, and thus assume
  it's not mounted.  This causes "zfs unmount", "zfs destroy",
  etc. to fail on these filesystems, whether or not -f is passed.

59adbba20f xen: fix blkback pushing responses before releasing internal resources
Fix a problem where the blockback driver could run out of requests,
despite the fact that we allocate enough request and reqlist
structures to satisfy the maximum possible number of requests.

The problem was that we were sending responses back to the other
end (blockfront) before freeing resources. The Citrix Windows
driver is pretty agressive about queueing, and would queue more I/O
to us immediately after we sent responses to it. We would run into
a resource shortage and stall out I/O until we freed resources.

It isn't clear whether the request shortage condition was an
indirect cause of the I/O hangs we've been seeing between Windows
with the Citrix PV drivers and FreeBSD's blockback, but the above
problem is certainly a bug.

dev/xen/blkback/blkback.c:
 - Break xbb_send_response() into two sub-functions,
   xbb_queue_response() and xbb_push_responses().
   Remove xbb_send_response(), because it is no longer
   used.

 - Adjust xbb_complete_reqlist() so that it calls the
   two new functions, and holds the mutex around both
   calls.  The mutex insures that another context
   can't come along and push responses before we've
   freed our resources.

 - Change xbb_release_reqlist() so that it requires
   the mutex to be held instead of acquiring the mutex
   itself.  Both callers could easily hold the mutex
   while calling it, and one really needs to hold the
   mutex during the call.

 - Add two new counters, accessible via sysctl
   variables.  The first one counts the number of
   I/Os that are queued and waiting to be pushed
   (reqs_queued_for_completion).  The second one
   (reqs_completed_with_error) counts the number of
   requests we've completed with an error status.

 - Add a callback in the xenstore interrupt filter that will trigger

   interrupt. This interrupt is generated when xenstored attaches to
   the event channel, and serves as a notification that xenstored is
   running.

 - The MSI interrupts will use the same PIC as the IO APIC interrupts.

xen/xen_msi.h:

 - Introduce a Xen MSI implementation.

x86/xen/xen_nexus.c:
 - Overwrite the default MSI hooks in the Xen Nexus to use the Xen MSI
   implementation.

x86/xen/xen_pci.c:
 - Introduce a Xen specific PCI bus that inherits from the ACPI PCI
   bus and overwrites the native MSI methods.
 - This is needed because when running under Xen the MSI messages used
   to configure MSI interrupts on PCI devices are written by Xen
   itself.

dev/acpica/acpi_pci.c:
 - Lower the quality of the ACPI PCI bus so the newly introduced Xen
   PCI bus can take over when needed.
