This is a relatively large set of fixes, the bulk of it being a series
from Lukas Wunner which fixes confusion with the lifetime of driver data
allocated along with the SPI controller structure that's been created as
part of the conversion to devm APIs. The simplest fix, explained in
detail in Lukas' commit message, is to move to a devm_ function for
allocation of the controller and hence driver data in order to push the
free of that after anything tries to reference the driver data in the
remove path. This results in a relatively large diff due to the
addition of a new function but isn't particularly complex.
There's also a fix from sven van Asbroeck which fixes yet more fallout
from the conflicts between the various different places one can
configure the polarity of GPIOs in modern systems.
Otherwise everything is fairly small and driver specific.

Jens has reported a situation where partial direct IOs can be issued
and completed yet still return -EAGAIN. We don't want this to report
a short IO as we want XFS to complete user DIO entirely or not at
all.
This partial IO situation can occur on a write IO that is split
across an allocated extent and a hole, and the second mapping is
returning EAGAIN because allocation would be required.
The trivial reproducer:
$ sudo xfs_io -fdt -c "pwrite 0 4k" -c "pwrite -V 1 -b 8k -N 0 8k" /mnt/scr/foo
wrote 4096/4096 bytes at offset 0
4 KiB, 1 ops; 0.0001 sec (27.509 MiB/sec and 7042.2535 ops/sec)
pwrite: Resource temporarily unavailable
$
The pwritev2(0, 8kB, RWF_NOWAIT) call returns EAGAIN having done
the first 4kB write:
xfs_file_direct_write: dev 259:1 ino 0x83 size 0x1000 offset 0x0 count 0x2000
iomap_apply: dev 259:1 ino 0x83 pos 0 length 8192 flags WRITE|DIRECT|NOWAIT (0x31) ops xfs_direct_write_iomap_ops caller iomap_dio_rw actor iomap_dio_actor
xfs_ilock_nowait: dev 259:1 ino 0x83 flags ILOCK_SHARED caller xfs_ilock_for_iomap
xfs_iunlock: dev 259:1 ino 0x83 flags ILOCK_SHARED caller xfs_direct_write_iomap_begin
xfs_iomap_found: dev 259:1 ino 0x83 size 0x1000 offset 0x0 count 8192 fork data startoff 0x0 startblock 24 blockcount 0x1
iomap_apply_dstmap: dev 259:1 ino 0x83 bdev 259:1 addr 102400 offset 0 length 4096 type MAPPED flags DIRTY
Here the first iomap loop has mapped the first 4kB of the file and
issued the IO, and we enter the second iomap_apply loop:
iomap_apply: dev 259:1 ino 0x83 pos 4096 length 4096 flags WRITE|DIRECT|NOWAIT (0x31) ops xfs_direct_write_iomap_ops caller iomap_dio_rw actor iomap_dio_actor
xfs_ilock_nowait: dev 259:1 ino 0x83 flags ILOCK_SHARED caller xfs_ilock_for_iomap
xfs_iunlock: dev 259:1 ino 0x83 flags ILOCK_SHARED caller xfs_direct_write_iomap_begin
And we exit with -EAGAIN out because we hit the allocate case trying
to make the second 4kB block.
Then IO completes on the first 4kB and the original IO context
completes and unlocks the inode, returning -EAGAIN to userspace:
xfs_end_io_direct_write: dev 259:1 ino 0x83 isize 0x1000 disize 0x1000 offset 0x0 count 4096
xfs_iunlock: dev 259:1 ino 0x83 flags IOLOCK_SHARED caller xfs_file_dio_aio_write
There are other vectors to the same problem when we re-enter the
mapping code if we have to make multiple mappinfs under NOWAIT
conditions. e.g. failing trylocks, COW extents being found,
allocation being required, and so on.
Avoid all these potential problems by only allowing IOMAP_NOWAIT IO
to go ahead if the mapping we retrieve for the IO spans an entire
allocated extent. This avoids the possibility of subsequent mappings
to complete the IO from triggering NOWAIT semantics by any means as
NOWAIT IO will now only enter the mapping code once per NOWAIT IO.

Some users are pairing the Dinovo keyboards with the MX5000 or MX5500
receivers, instead of with the Dinovo receivers. The receivers are
mostly the same (and the air protocol obviously is compatible) but
currently the Dinovo receivers are handled by hid-lg.c while the
MX5x00 receivers are handled by logitech-dj.c.
When using a Dinovo keyboard, with its builtin touchpad, through
logitech-dj.c then the touchpad stops working because when asking the
receiver for paired devices, we get only 1 paired device with
a device_type of REPORT_TYPE_KEYBOARD. And since we don't see a paired
mouse, we have nowhere to send mouse-events to, so we drop them.
Extend the existing fix for the Dinovo Edge for this to also cover the
Dinovo Mini keyboard and also add a mapping to logitech-hidpp for the
Media key on the Dinovo Mini, so that that keeps working too.

The HDMI controller cannot go above a certain pixel rate limit depending on
the generations, but that limit is only enforced in mode_valid at the
moment, which means that we won't advertise modes that exceed that limit,
but the userspace is still free to try to setup a mode that would.
Implement atomic_check to make sure we check it in that scenario too.

Variant 1 needs the exact same quirk as variant 2, so relax the DMI check
for the existing quirk a bit so that it matches both variant 1 and 2
(note the other variants will still not match).
Variant 2 already has an existing quirk (which now also matches variant 1)
Variant 3 uses a cx2072x codec, so is not applicable here.
Variant 4 almost works with the defaults, but it also needs a quirk to
fix jack-detection, add a new quirk for this.
Variant 5 does use a RT5640 codec (based on old dmesg output), but was
otherwise not tested, keep using the defaults for this variant.

In kup.h we currently include kup-radix.h for all 64-bit builds, which
includes Book3S and Book3E. The latter doesn't make sense, Book3E
never uses the Radix MMU.
This has worked up until now, but almost by accident, and the recent
uaccess flush changes introduced a build breakage on Book3E because of
the bad structure of the code.
So disentangle things so that we only use kup-radix.h for Book3S. This
requires some more stubs in kup.h and fixing an include in
syscall_64.c.

IBM Power9 processors can speculatively operate on data in the L1 cache
before it has been completely validated, via a way-prediction mechanism. It
is not possible for an attacker to determine the contents of impermissible
memory using this method, since these systems implement a combination of
hardware and software security measures to prevent scenarios where
protected data could be leaked.
However these measures don't address the scenario where an attacker induces
the operating system to speculatively execute instructions using data that
the attacker controls. This can be used for example to speculatively bypass
"kernel user access prevention" techniques, as discovered by Anthony
Steinhauser of Google's Safeside Project. This is not an attack by itself,
but there is a possibility it could be used in conjunction with
side-channels or other weaknesses in the privileged code to construct an
attack.
This issue can be mitigated by flushing the L1 cache between privilege
boundaries of concern. This patch flushes the L1 cache after user accesses.
This is part of the fix for CVE-2020-4788.

the number of L1D flushes over a syscall with the RFI flush enabled and

If there is a debugfs entry for the entry flush, disable it during the RFI

- Cure the fallout from the MSI irqdomain overhaul which missed that the
Intel IOMMU does not register virtual function devices and therefore
never reaches the point where the MSI interrupt domain is assigned. This
makes the VF devices use the non-remapped MSI domain which is trapped by
the IOMMU/remap unit.
- Remove an extra space in the SGI_UV architecture type procfs output for
UV5.
- Remove a unused function which was missed when removing the UV BAU TLB
shootdown handler.

EDID can declare the maximum supported bpc up to 16,
and apparently there are displays that do so. Currently
we assume 12 bpc is tha max. Fix the assumption and
toss in a MISSING_CASE() for any other value we don't
expect to see.
This fixes modesets with a display with EDID max bpc > 12.
Previously any modeset would just silently fail on platforms
that didn't otherwise limit this via the max_bpc property.
In particular we don't add the max_bpc property to HDMI
ports on gmch platforms, and thus we would see the raw
max_bpc coming from the EDID.
I suppose we could already adjust this to also allow 16bpc,
but seeing as no current platform supports that there is
little point.
