- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.

media: videobuf2: Drop minimum allocation requirement of 2 buffers

When introducing the ability for drivers to indicate the minimum number
of buffers they require an application to allocate, commit 6662edcd32cc
("media: videobuf2: Add min_reqbufs_allocation field to vb2_queue
structure") also introduced a global minimum of 2 buffers. It turns out
this breaks the Renesas R-Car VSP test suite, where a test that
allocates a single buffer fails when two buffers are used.

One may consider debatable whether test suite failures without failures
in production use cases should be considered as a regression, but
operation with a single buffer is a valid use case. While full frame
rate can't be maintained, memory-to-memory devices can still be used
with a decent efficiency, and requiring applications to allocate
multiple buffers for single-shot use cases with capture devices would
just waste memory.

For those reasons, fix the regression by dropping the global minimum of
buffers. Individual drivers can still set their own minimum.

media: videobuf2-core: attach once if multiple planes share the same dbuf

When multiple planes use the same dma buf, each plane will have its own dma
buf attachment and mapping. It is a waste of IOVA space.

This patch adds a dbuf_duplicated boolean in vb2_plane. If a plane's dbuf
is the same as an existing plane, do not create another attachment and
mapping.

Split the for loop into 3 parts
1. In the first for loop, validate planes and check if planes changed.
2. Call __vb2_buf_dmabuf_put() to release all planes.
3. In the second for loop, reaquire new planes.
