Ensure make -j N universe works correctly, by checking for an up-to-date
make before starting the universe targets themselves. Otherwise, all of
the targets would attempt to build make simultaneously, overwriting each

to strange errors, for example when partially-written make executables
are invoked.
Also amend r216620, to make the rest of universe wait properly until the
upgrade_checks target is finished, by adding universe_${target}_prologue
to the .ORDER target. Otherwise, make will be too smart for its own
good, and start building the universe targets simultaneously with the
prologues anyway.

Pull in r178636 from upstream llvm trunk:
Second pass at addressing PR15351 by explicitly checking for AVX
support when getting the host processor information. It emits a
.byte sequence on GNUC compilers to work around lack of xgetbv
support with older assemblers, and resolves a comment typo found in
the previous patch.
This should fix crashes due to emitting of AVX instructions on certain
processors, which do not support then, when using -march=native.
This is a direct commit to stable/9, since head has a complete import of
llvm/clang trunk, and there is no single commit to merge.
Don't directly dereference userland pointer; instead use kernel pointer
copied in from userspace. This fixes instant panic when creating CTL LUN

Make CTL work a little better with loading and unloading drivers.
Previously CTL would leave individual LUNs enabled in the target
driver, whether or not the port as a whole was enabled. It would
also leave the wildcard LUN enabled indefinitely.
This change means that CTL will enable and disable any active LUNs,
as well as the wildcard LUN, when enabling and disabling a port.
Also, fix a bug that could crop up due to an uninitialized CCB
type.
ctl.c: Before calling ctl_frontend_online(), run through
the LUN list and enable all active LUNs.
After calling ctl_frontend_offline(), run through
the LUN list and disble all active LUNs.
scsi_ctl.c: Before bringing a port online, allocate the
wildcard peripheral for that bus. And after taking
a port offline, invalidate the wildcard peripheral
for that bus.
Make sure that we hold the SIM lock around all
calls to xpt_action() and other transport layer
interfaces that require it.
Use CAM_SIM_{LOCK|UNLOCK} consistently to acquire
and release the SIM lock.
Update a number of outdated comments. Some of
these should have been fixed long ago.
Actually do LUN disbables now. The newer drivers
in the tree work correctly for this as far as I
know.
Initialize the CCB type to CTLFE_CCB_DEFAULT to
avoid a panic due to uninitialized memory.

MFC r238886, r238892:
Implement media change notification for DA and CD removable media devices.
It includes three parts:
1) Modifications to CAM to detect media media changes and report them to
disk(9) layer. For modern SATA (and potentially UAS) devices it utilizes
Asynchronous Notification mechanism to receive events from hardware.
Active polling with TEST UNIT READY commands with 3 seconds period is used
for incapable hardware. After that both CD and DA drivers work the same way,
detecting two conditions: "NOT READY: Medium not present" after medium was
detected previously, and "UNIT ATTENTION: Not ready to ready change, medium
may have changed". First one reported to disk(9) as media removal, second
as media insert/change. To reliably receive second event new
AC_UNIT_ATTENTION async added to make UAs broadcasted to all periphs by
generic error handling code in cam_periph_error().
2) Modifications to GEOM core to handle media remove and change events.
Media removal handled by spoiling all consumers attached to the provider.
Media change event also schedules provider retaste after spoiling to probe
new media. New flag G_CF_ORPHAN was added to consumers to reflect that
consumer is in process of destruction. It allows retaste to create new
geom instance of the same class, while previous one is still dying.
3) Modifications to some GEOM classes: DEV -- to report media change
events to devd; PART class already handles spoiling alike to orphan.

Use the topology lock to protect list of providers while withering them.
It is possible that provider is destroyed while we are iterating over the

Remove the topology lock from disk_gone(), it might be called with regular
mutexes held and the topology lock is an sx lock.
The topology lock was there to protect traversing through the list of providers
of disk's geom, but it seems that disk's geom has always exactly one provider.

safe to do without holding the topology lock and assert that there is indeed
only one provider.
MFC r238198 (by trasz):

- delay consumer closing and detaching on orphan() until all I/Os complete;

MFC r237689 (by imp):
Add a sysctl to set the cdrom timeout. Data recovery operations from
