SoCs featuring peripherals that can issue non-coherent DMA traffic
beyond the point of coherency (PoC) present multiple challenges for the
DMA-API implementation in Linux. Many of these challenges can be
overcome by suitable configuration of the interconnect, however the
presence of a cacheable alias for non-cacheable buffers can still lead
to coherence issues arising when stale clean lines are back-snooped from
the cache hierarchy to satisfy a non-cacheable transaction at the PoC.
Removing all cacheable aliases on a case-by-cases basis is both
error-prone and expensive. Instead, leverage the stage-2 identity
mapping installed by pKVM to enforce consistent cacheability for all
stage-1 aliases.

Some Qualcomm firmwares may crash on the "Call UID" query to hypervisor.
This call is made to check which hypervisor implmenetation Linux may be
a guest under. Move this check under the Gunyah RM driver probe so that
it is only made when Gunyah is definitely present.
This patch is destined for version 12 of the Gunyah patches posted to
kernel.org.

The greybus loopback test tool does not belong burried down in a
driver-specific directory. If it is needed, it should be somewhere
else, like in the testing directory. But as the loopback driver is
probably never going to be merged out of the staging directory, let's
just delete the test alltogether for now. If it's needed in the future,
it can be brought back with a revert.
Also, having an Android.mk file in the kernel source tree breaks some
Android build systems when trying to build from a read-only source tree,
the report of which prompted this being a good reason to remove it as
well.

pKVM module loading is disabled by rejecting the HVCs. This is a problem
for kvm_call_hyp_nvhe(__pkvm_alloc_module_va). First a WARN will be
trigger, then the res.a1 being very much likely non 0 the error will
not be caught. The loading would then proceed (even though no EL2 code
will be actually loaded).
Fix this behaviour by catching when the HVC is blocked, so the user gets
a meaningful error returned and the driver is not half-loaded.

commit 0482c34ec6 upstream.
ucsi_init() which runs from a workqueue sets ucsi->connector and
on an error will clear it again.
ucsi->connector gets dereferenced by ucsi_resume(), this checks for
ucsi->connector being NULL in case ucsi_init() has not finished yet;
or in case ucsi_init() has failed.
ucsi_init() setting ucsi->connector and then clearing it again on
an error creates a race where the check in ucsi_resume() may pass,
only to have ucsi->connector free-ed underneath it when ucsi_init()
hits an error.
Fix this race by making ucsi_init() store the connector array in
a local variable and only assign it to ucsi->connector on success.

[ Upstream commit 4fb877aaa1 ]
Fix bug in btf_dump's logic of determining if a given struct type is
packed or not. The notion of "natural alignment" is not needed and is
even harmful in this case, so drop it altogether. The biggest difference
in btf_is_struct_packed() compared to its original implementation is
that we don't really use btf__align_of() to determine overall alignment
of a struct type (because it could be 1 for both packed and non-packed
struct, depending on specifci field definitions), and just use field's
actual alignment to calculate whether any field is requiring packing or
struct's size overall necessitates packing.
Add two simple test cases that demonstrate the difference this change
would make.

[ Upstream commit ea2ce1ba99 ]
Turns out that btf_dump API doesn't handle a bunch of tricky corner
cases, as reported by Per, and further discovered using his testing
Python script ([0]).
This patch revamps btf_dump's padding logic significantly, making it
more correct and also avoiding unnecessary explicit padding, where
compiler would pad naturally. This overall topic turned out to be very
tricky and subtle, there are lots of subtle corner cases. The comments
in the code tries to give some clues, but comments themselves are
supposed to be paired with good understanding of C alignment and padding
rules. Plus some experimentation to figure out subtle things like
whether `long :0;` means that struct is now forced to be long-aligned
(no, it's not, turns out).
Anyways, Per's script, while not completely correct in some known
situations, doesn't show any obvious cases where this logic breaks, so
this is a nice improvement over the previous state of this logic.
Some selftests had to be adjusted to accommodate better use of natural
alignment rules, eliminating some unnecessary padding, or changing it to
`type: 0;` alignment markers.
Note also that for when we are in between bitfields, we emit explicit
bit size, while otherwise we use `: 0`, this feels much more natural in
practice.
Next patch will add few more test cases, found through randomized Per's
script.

commit 8646384d80 upstream.
In applications where the switch ports must perform 802.1X based
authentication and are therefore locked, ATU violation interrupts are
quite to be expected as part of normal operation. The problem is that
they currently spam the kernel log, even if rate limited.
Create a series of trace points, all derived from the same event class,
which log these violations to the kernel's trace buffer, which is both
much faster and much easier to ignore than printing to a serial console.
New usage model:
$ trace-cmd list | grep mv88e6xxx
mv88e6xxx
mv88e6xxx:mv88e6xxx_atu_full_violation
mv88e6xxx:mv88e6xxx_atu_miss_violation
mv88e6xxx:mv88e6xxx_atu_member_violation
$ trace-cmd record -e mv88e6xxx sleep 10

commit 4bf24ad09b upstream.
When an ATU violation occurs, the switch uses the ATU FID register to
report the FID of the MAC address that incurred the violation. It would
be good for the driver to know the FID value for purposes such as
logging and CPU-based authentication.
Up until now, the driver has been calling the mv88e6xxx_g1_atu_op()
function to read ATU violations, but that doesn't do exactly what we
want, namely it calls mv88e6xxx_g1_atu_fid_write() with FID 0.
(side note, the documentation for the ATU Get/Clear Violation command
says that writes to the ATU FID register have no effect before the
operation starts, it's only that we disregard the value that this
register provides once the operation completes)
So mv88e6xxx_g1_atu_fid_write() is not what we want, but rather
mv88e6xxx_g1_atu_fid_read(). However, the latter doesn't exist, we need
to write it.
The remainder of mv88e6xxx_g1_atu_op() except for
mv88e6xxx_g1_atu_fid_write() is still needed, namely to send a
GET_CLR_VIOLATION command to the ATU. In principle we could have still
kept calling mv88e6xxx_g1_atu_op(), but the MDIO writes to the ATU FID
register are pointless, but in the interest of doing less CPU work per
interrupt, write a new function called mv88e6xxx_g1_read_atu_violation()
and call it.
The FID will be the port default FID as set by mv88e6xxx_port_set_fid()
if the VID from the packet cannot be found in the VTU. Otherwise it is
the FID derived from the VTU entry associated with that VID.

commit e86fc1a3a3 upstream.
We walk the userspace PTs to discover what mapping size was
used there. However, this can race against the userspace tables
being freed, and we end-up in the weeds.
Thankfully, the mm code is being generous and will IPI us when
doing so. So let's implement our part of the bargain and disable
interrupts around the walk. This ensures that nothing terrible
happens during that time.
We still need to handle the removal of the page tables before
the walk. For that, allow get_user_mapping_size() to return an
error, and make sure this error can be propagated all the way
to the the exit handler.

commit 9228b26194 upstream.
Have KVM_GET_ONE_REG for vPMU counter (vPMC) registers (PMCCNTR_EL0
and PMEVCNTR<n>_EL0) return the sum of the register value in the sysreg
file and the current perf event counter value.
Values of vPMC registers are saved in sysreg files on certain occasions.
These saved values don't represent the current values of the vPMC
registers if the perf events for the vPMCs count events after the save.
The current values of those registers are the sum of the sysreg file
value and the current perf event counter value. But, when userspace
reads those registers (using KVM_GET_ONE_REG), KVM returns the sysreg
file value to userspace (not the sum value).
Fix this to return the sum value for KVM_GET_ONE_REG.

commit a8e03e00b6 upstream.
SKL/GLK CSC unit suffers from a nasty issue where a CSC
coeff/offset register read or write between DC5 exit and
PSR exit will undo the CSC arming performed by DMC, and
then during PSR exit the hardware will latch zeroes into
the active CSC registers. This causes any plane going
through the CSC to output all black.
We can sidestep the issue by making sure the PSR exit has
already actually happened before we touch the CSC coeff/offset
registers. Easiest way to guarantee that is to just move the
CSC programming back into the .color_commir_arm() as we force
a PSR exit (and crucially wait for it to actually happen)
prior to touching the arming registers.
When PSR (and thus also DC states) are disabled we don't
have anything to worry about, so we can keep using the
more optional _noarm() hook for writing the CSC registers.

commit a2b6e99d8a upstream.
Keeping DC states enabled is incompatible with the _noarm()/_arm()
split we use for writing pipe/plane registers. When DC5 and PSR
are enabled, all pipe/plane registers effectively become self-arming
on account of DC5 exit arming the update, and PSR exit latching it.
What probably saves us most of the time is that (with PIPE_MISC[21]=0)
all pipe register writes themselves trigger PSR exit, and then
we don't re-enter PSR until the idle frame count has elapsed.
So it may be that the PSR exit happens already before we've
updated the state too much.
Also the PSR1 panel (at least on this KBL) seems to discard the first
frame we trasmit, presumably still scanning out from its internal
framebuffer at that point. So only the second frame we transmit is
actually visible. But I suppose that could also be panel specific
behaviour. I haven't checked out how other PSR panels behave, nor
did I bother to check what the eDP spec has to say about this.
And since this really is all about DC states, let's switch from
the MODESET domain to the DC_OFF domain. Functionally they are
100% identical. We should probably remove the MODESET domain...
And for good measure let's toss in an assert to the place where
we do the _noarm() register writes to make sure DC states are
in fact off.

drm_gem_prime_mmap() takes a reference on the GEM object, but before that
drm_gem_mmap_obj() already takes a reference, which will be leaked as only
one reference is dropped when the mapping is closed. Drop the extra
reference when dma_buf_mmap() succeeds.
