Commit 71054d8841b4 ("x86, hpet: Introduce x86_msi_ops.setup_hpet_msi")
introduced x86_msi_ops.setup_hpet_msi to setup hpet MSI irq
when irq remapping enabled. This caused a regression of
hpet MSI irq remapping.
Original code flow before commit 71054d8841b4:
hpet_setup_msi_irq()
arch_setup_hpet_msi()
setup_hpet_msi_remapped()
remap_ops->setup_hpet_msi()
alloc_irte()
msi_compose_msg()
hpet_msi_write()
...
Current code flow after commit 71054d8841b4:
hpet_setup_msi_irq()
x86_msi.setup_hpet_msi()
setup_hpet_msi_remapped()
intel_setup_hpet_msi()
alloc_irte()
Currently, we only call alloc_irte() for hpet MSI, but
do not composed and wrote its msg...

iommu_bus_init() registers a bus notifier on the given bus by using
a statically defined notifier block:
static struct notifier_block iommu_bus_nb = {
.notifier_call = iommu_bus_notifier,
};
This same notifier block is used for all busses. This causes a
problem for notifiers registered after iommu has registered this
callback on multiple busses. The problem is that a subsequent
notifier being registered on a bus which has this iommu notifier
will also get linked in to the notifier list of all other busses
which have this iommu notifier.
This patch fixes this by allocating the notifier_block at runtime.
Some error checking is also added to catch any allocation failure
or notifier registration error.

For a PCI device, aliases from the IVRS table won't be populated
into dma_alias_devfn until after iommu_init_device() is called on
each device. We therefore want to split init_iommu_group() to
be called from a separate loop immediately following.

It turns out that our assumption that aliases are always to the same
slot isn't true. One particular platform reports an IVRS alias of the
SATA controller (00:11.0) for the legacy IDE controller (00:14.1).
When we hit this, we attempt to use a single IOMMU group for
everything on the same bus, which in this case is the root complex.
We already have multiple groups defined for the root complex by this
point, resulting in multiple WARN_ON hits.
This patch makes these sorts of aliases work again with IOMMU groups
by reworking how we search through the PCI address space to find
existing groups. This should also now handle looped dependencies and
all sorts of crazy inter-dependencies that we'll likely never see.
The recursion used here should never be very deep. It's unlikely to
have individual aliases and only theoretical that we'd ever see a
chain where one alias causes us to search through to yet another
alias. We're also only dealing with PCIe device on a single bus,
which means we'll typically only see multiple slots in use on the root
complex. Loops are also a theoretically possibility, which I've
tested using fake DMA alias quirks and prevent from causing problems
using a bitmap of the devfn space that's been visited.

This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB-
SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The
US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI
chain to be accessed. Without it only the (single) device with SCSI ID 0
can be used.
The standalone converter sold by Entrega had model number U1-SC25. Xircom
acquired Entrega and re-branded the product line PortGear. The PortGear USB
to SCSI Converter (model PGSCSI) is internally identical to the Entrega
product, but later models may use a different USB ID. The Entrega-branded
units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and
Macintosh drivers also support 085A:0028.
Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac
(8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as
a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may
have initially used the same ID as the standalone U1-SC25 (1645:0007), but
later production used 085A:0026.
My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133
probably also exist.
This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows
driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I
couldn't find any mention of that actually existing in the wild; perhaps it
was cancelled before release?

Hi,
The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g.
iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM
Microsystems chips. Only the connectors differ; both have the same USB ID.
The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other
than 0.
I don't have one of these, but based on the other entries for Shuttle/
SCM-based converters this patch is very likely correct. I used 0x0000 and
0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which
bcdDevice value the products use.

Old code in ehci-hcd tries to expedite disabling endpoints after the
controller has stopped, by destroying the endpoint's associated QH
without first unlinking the QH. This was necessary back when the
driver wasn't so careful about keeping track of the controller's
state.
But now we are careful about it, and the driver knows that when the
controller isn't running, no unlinking delay is needed. Furthermore,
skipping the unlink step will trigger a BUG() in qh_destroy() when the
preceding QH is released, because the link pointer will be non-NULL.
Removing the lines that skip the unlinking step and go directly to
QH_STATE_IDLE fixes the problem.
