On MMIO devices (e.g. MT7988 or EN7581) unicast traffic received on lanX
port is flooded on all other user ports if the DSA switch is configured
without VLAN support since PORT_MATRIX in PCR regs contains all user
ports. Similar to MDIO devices (e.g. MT7530 and MT7531) fix the issue
defining default VLAN-ID 0 for MT7530 MMIO devices.

Implement i915_gem_vmap_object() and i915_gem_vunmap_object(),
based on i915_gem_dmabuf_vmap() and i915_gem_dmabuf_vunmap().
This enables a drm_client to use drm_client_buffer_vmap() and
drm_client_buffer_vunmap() on hardware using the i915 driver.
Tested with a currently out of tree pixelflut drm_client[1] on:
- Lenovo ThinkCentre M720q (CoffeeLake-S GT2 / Intel UHD Graphics 630)

The IOPOLL path posts CQEs when the io_kiocb is marked as completed,
so it cannot rely on the usual retry that non-IOPOLL requests do for
read/write requests.
If -EAGAIN is received and the request should be retried, go through
the normal completion path and let the normal flush logic catch it and
reissue it, like what is done for !IOPOLL reads or writes.

information (version and name) is represented in a single struct type,
we can extract duplicated logic from handle_pre_gmdid() and
handle_gmdid() and apply it in the body of xe_info_init().

We have now a struct xe_ip to fully describe an IP, but we are only
using that for GMDID-based IPs.
For pre-GMDID IPs, we still describe release info (version and name) via
feature descriptors (struct xe_{graphics,media}_desc). Let's convert
those to use struct xe_ip.
With this, we have a uniform way of describing IPs in the xe driver
instead of having different approaches based on whether the IPs use
GMDIDs or not.
A nice side-effect of this change is that now we have an easy way to
lookup, in the source code, mappings between versions, names and
features for all supported IPs.

- Store pointers to struct xe_ip instead xe_{graphics,media}_desc in

If we pay closer attention to struct gmdid_map, we will realize that it
is actually fully describing an IP (graphics or media): it contains
"release info" and "features info". The former is comprised of fields
"ver" and "name"; and the latter is done via member "ip", which is a
pointer to either struct xe_graphics_desc or xe_media_desc, and can be
reused across releases.
As such let's:
* Rename struct gmdid_map to xe_ip.
* Rename the field ver to verx100 to be consistent with the naming of
members using that encoding of the version.
* Rename the field "ip" to "desc" to make it clear that it is a
pointer to a descriptor of features for the IP, since it will not
contain *all* info (i.e. features + release info).
We sill have release info mapped into struct xe_{graphics,media}_desc
for pre-GMDID IPs. In an upcoming change we will handle that so that we
make a clear separation between "release info" and "feature info".

The name of an IP is a function of its version. As such, given an IP
version, it should be clear to identify the name of that IP release.
With the current code, we keep that mapping clear for pre-GMDID IPs, but
ambiguous for GMDID-based ones. That causes two types of inconveniences:
1. The end user, who might not have all the necessary mapping at hand,
might be confused when seeing different possible IP names in the
dmesg log.
2. It makes a developer who is not familiar with the "IP version" to
"Release name" need to resort to looking at the specs to understand
see what version maps to what. While the specs should be the
authority on the mapping, we should make our lives easier by
reflecting that mapping in the source code.
Thus, since the IP name is tied to the version, let's remove the
ambiguity by using a "name" field in struct gmdid_map instead of
accumulating names in the descriptor instances.
This does result in the code having IP name being defined in
different structs (gmdid_map, xe_graphics_desc, xe_media_desc), but that
will be resolved in upcoming changes.
A side-effect of this change is that media_xe2 exactly matches
media_xelpmp now, so we just re-use the latter.
v2:
- Drop media_xe2 and re-use media_xelpmp. (Matt)

If userptr pages are freed after a call to the xe mmu notifier,
the device will not be blocked out from theoretically accessing
these pages unless they are also unmapped from the iommu, and
this violates some aspects of the iommu-imposed security.
Ensure that userptrs are unmapped in the mmu notifier to
mitigate this. A naive attempt would try to free the sg table, but
the sg table itself may be accessed by a concurrent bind
operation, so settle for only unmapping.

The pnfs that we obtain from hmm_range_fault() point to pages that
we don't have a reference on, and the guarantee that they are still
in the cpu page-tables is that the notifier lock must be held and the
notifier seqno is still valid.
So while building the sg table and marking the pages accesses / dirty
we need to hold this lock with a validated seqno.
However, the lock is reclaim tainted which makes
sg_alloc_table_from_pages_segment() unusable, since it internally
allocates memory.
Instead build the sg-table manually. For the non-iommu case
this might lead to fewer coalesces, but if that's a problem it can
be fixed up later in the resource cursor code. For the iommu case,
the whole sg-table may still be coalesced to a single contigous
device va region.
This avoids marking pages that we don't own dirty and accessed, and
it also avoid dereferencing struct pages that we don't own.
v2:
- Use assert to check whether hmm pfns are valid (Matthew Auld)
- Take into account that large pages may cross range boundaries

v3:
- Don't unnecessarily check for a non-freed sg-table. (Matthew Auld)

Concurrent VM bind staging and zapping of PTEs from a userptr notifier
do not work because the view of PTEs is not stable. VM binds cannot
acquire the notifier lock during staging, as memory allocations are
required. To resolve this race condition, use a staging tree for VM
binds that is committed only under the userptr notifier lock during the
final step of the bind. This ensures a consistent view of the PTEs in
the userptr notifier.
A follow up may only use staging for VM in fault mode as this is the
only mode in which the above race exists.

Fix fault mode invalidation racing with unbind leading to the
PTE zapping potentially traversing an invalid page-table tree.
Do this by holding the notifier lock across PTE zapping. This
might transfer any contention waiting on the notifier seqlock
read side to the notifier lock read side, but that shouldn't be
a major problem.
At the same time get rid of the open-coded invalidation in the bind
code by relying on the notifier even when the vma bind is not
yet committed.
Finally let userptr invalidation call a dedicated xe_vm function
performing a full invalidation.

If a userptr vma subject to prefetching was already invalidated
or invalidated during the prefetch operation, the operation would
repeatedly return -EAGAIN which would typically cause an infinite
loop.
Validate the userptr to ensure this doesn't happen.
v2:
- Don't fallthrough from UNMAP to PREFETCH (Matthew Brost)

The kernel_recvmsg() function returns an int which could be either
negative error codes or the number of bytes received. The problem is
that the condition:
if (ret < sizeof(*icresp)) {
is type promoted to type unsigned long and negative values are treated
as high positive values which is success, when they should be treated as
failure. Handle invalid positive returns separately from negative
error codes to avoid this problem.

Going forward, struct intel_display is the main display device data
pointer. Convert as much as possible of intel_display.c to struct
intel_display.
This exposes a couple of outside issues that need to be fixed as well,
in a register macro and a DSI PLL stub.

While looking for incorrect users of the pipe head/tail fields (see
commit c27c66afc449: "fs/pipe: Fix pipe_occupancy() with 16-bit
indexes"), I found a bug in pipe_discard_from() that looked entirely
broken.
However, the fix is trivial: this buggy function isn't actually called
by anything, so let's just remove it ASAP.
