vhost: add trace for IOTLB miss
Add some trace points for IOTLB translation for vhost. After vhost-user
is setup, the only IO path that QEMU will participate should be the
IOMMU translation, so it'll be good we can track this with explicit
timestamps when needed to see how long time we take to do the
translation, and whether there's anything stuck inside. It might be
useful for triaging vhost-user problems.

Log Message:
-----------
intel-iommu: send PSI always even if across PDEs
SECURITY IMPLICATION: without this patch, any guest with both assigned
device and a vIOMMU might encounter stale IO page mappings even if guest
has already unmapped the page, which may lead to guest memory
corruption. The stale mappings will only be limited to the guest's own
memory range, so it should not affect the host memory or other guests on
the host.
During IOVA page table walking, there is a special case when the PSI
covers one whole PDE (Page Directory Entry, which contains 512 Page
Table Entries) or more. In the past, we skip that entry and we don't
notify the IOMMU notifiers. This is not correct. We should send UNMAP
notification to registered UNMAP notifiers in this case.
For UNMAP only notifiers, this might cause IOTLBs cached in the devices
even if they were already invalid. For MAP/UNMAP notifiers like
vfio-pci, this will cause stale page mappings.
This special case doesn't trigger often, but it is very easy to be
triggered by nested device assignments, since in that case we'll
possibly map the whole L2 guest RAM region into the device's IOVA
address space (several GBs at least), which is far bigger than normal
kernel driver usages of the device (tens of MBs normally).
Without this patch applied to L1 QEMU, nested device assignment to L2
guests will dump some errors like:
qemu-system-x86_64: VFIO_MAP_DMA: -17
qemu-system-x86_64: vfio_dma_map(0x557305420c30, 0xad000, 0x1000,

intel-iommu: add iommu lock
SECURITY IMPLICATION: this patch fixes a potential race when multiple
threads access the IOMMU IOTLB cache.
Add a per-iommu big lock to protect IOMMU status. Currently the only
thing to be protected is the IOTLB/context cache, since that can be
accessed even without BQL, e.g., in IO dataplane.
Note that we don't need to protect device page tables since that's fully
controlled by the guest kernel. However there is still possibility that
malicious drivers will program the device to not obey the rule. In that
case QEMU can't really do anything useful, instead the guest itself will
be responsible for all uncertainties.

intel-iommu: introduce vtd_page_walk_info
During the recursive page walking of IOVA page tables, some stack
variables are constant variables and never changed during the whole page
walking procedure. Isolate them into a struct so that we don't need to
pass those contants down the stack every time and multiple times.

intel-iommu: trace domain id during page walk
This patch only modifies the trace points.
Previously we were tracing page walk levels. They are redundant since
we have page mask (size) already. Now we trace something much more
useful which is the domain ID of the page walking. That can be very
useful when we trace more than one devices on the same system, so that
we can know which map is for which domain.

intel-iommu: rework the page walk logic
This patch fixes a potential small window that the DMA page table might
be incomplete or invalid when the guest sends domain/context
invalidations to a device. This can cause random DMA errors for
assigned devices.
This is a major change to the VT-d shadow page walking logic. It
includes but is not limited to:
- For each VTDAddressSpace, now we maintain what IOVA ranges we have
mapped and what we have not. With that information, now we only send
MAP or UNMAP when necessary. Say, we don't send MAP notifies if we
know we have already mapped the range, meanwhile we don't send UNMAP
notifies if we know we never mapped the range at all.
- Introduce vtd_sync_shadow_page_table[_range] APIs so that we can call
in any places to resync the shadow page table for a device.
- When we receive domain/context invalidation, we should not really run
the replay logic, instead we use the new sync shadow page table API to
resync the whole shadow page table without unmapping the whole
region. After this change, we'll only do the page walk once for each
domain invalidations (before this, it can be multiple, depending on
number of notifiers per address space).
While at it, the page walking logic is also refactored to be simpler.
