sys/dev/xen/blkback/blkback.c:
Replace FreeBSD specific multi-page ring impelementation with
support for both the Citrix and Amazon/RedHat versions of this
extension.
sys/dev/xen/blkfront/blkfront.c:
o Add a per-instance sysctl tree that exposes all negotiated
transport parameters (ring pages, max number of requests,
max request size, max number of segments).
o In blkfront_vdevice_to_unit() add a missing return statement
so that we properly identify the unit number for high numbered
xvd devices.
sys/dev/xen/blkback/blkback.c:
o Add static dtrace probes for several events in this driver.
o Defer connection shutdown processing until the front-end
enters the closed state. This avoids prematurely tearing
down the connection when buggy front-ends transition to the
closing state, even though the device is open and they
veto the close request from the tool stack.
o Add nodes for maximum request size and the number of active
ring pages to the exising, per-instance, sysctl tree.
o Miscelaneous style cleanup.
sys/xen/interface/io/blkif.h:
o Add extensive documentation of the XenStore nodes used to
implement the blkif interface.
o Document the startup sequence between a front and back driver.
o Add structures and documenatation for the "discard" feature
(AKA Trim).
o Cleanup some definitions related to FreeBSD's request
number/size/segment-limit extension.
sys/dev/xen/blkfront/blkfront.c:
sys/dev/xen/blkback/blkback.c:
sys/xen/xenbus/xenbusvar.h:
Add the convenience function xenbus_get_otherend_state() and
use it to simplify some logic in both block-front and block-back.

set all three of the kernel, supervisor, and user-mode 64-bit mode
flags. While FreeBSD does not currently use the supervisor ring (and
hence this is effectively a NOP on most systems), doing this avoids
triggering an exception on 64-bit MIPS CPUs that don't support 32-bit
compatibility mode, and therefore don't allow clearing the SX bit.

The lang/gcc* ports patch headers where they think something is

2. Add a new option to bypass checking only that the service is enabled
at boot time, and always check if it is running.
3. Use this new functionality to greatly simplify the rc.d scripts that
use force_depend.
4. Add a force_depend for statd in lockd
5. Remove the check that either nfs_server or nfs_client is _enable'd

through by VMware so blacklist their PCI-PCI bridge for MSI/MSI-X here.
Note that besides currently there not being a quirk type that disables
MSI-X only and there's no evidence that MSI doesn't work with the VMware
pass-through, it's really questionable whether MSI generally works in
that setup as VMware only mention three know working devices [1, p. 4].
Also not that this quirk entry currently doesn't affect the devices
emulated by VMware in any way as these don't claim support MSI/MSI-X to
begin with. [2]
While at it, make the PCI quirk table const and static.

When performing a firmware upgrade via atacontrol[1] the subsequent
command may time out producing the error message above. When this
happens the callout could still be active, and the system would then
panic due to a destroyed semaphore.
Instead, ensure that the callout is done first, via callout_drain.
Note that this fix applies to the "old" ata(4) and so isn't applicable
to the default configuration in HEAD. It is still applicable to
stable/8.
