ARM: dts: Permanently disable hdmi1 and ddc1 on CM4S

CM4S has no HDMI1 output, so it is advisable to disable the controller
and its I2C interface in software. This is ordinarily done by setting
their status properties to "disabled", but the vc4-kms-v3d(-pi4)
overlay enables both HDMIs and DDCs as part of the transfer of control
from the VPU.

Knobble the CM4S dts in such a way that the overlay applies
successfully but the hdmi1 and ddc1 nodes remain disabled by changing
the compatible string to something unrecognised.

dtoverlay: Reduce size of PCIE IB window in pcie-32-dma overlay

The PCIE inbound window is rounded up to a power of 2, so the default
of 3GB rounds up to 4GB starting at 0. This prohibits the MSI vector
sitting at 0x0_fffffffc, and causes warnings from some subsystems
(eg ahci) of a 64bit address on a 32bit configuration.

Reduce the window down to 2GB to avoid this issue.

drm/vmwgfx: Fix stale file descriptors on failed usercopy

commit a0f90c8815706981c483a652a6aefca51a5e191c upstream.

A failing usercopy of the fence_rep object will lead to a stale entry in
the file descriptor table as put_unused_fd() won't release it. This
enables userland to refer to a dangling 'file' object through that still
valid file descriptor, leading to all kinds of use-after-free
exploitation scenarios.

Fix this by deferring the call to fd_install() until after the usercopy
has succeeded.

select: Fix indefinitely sleeping task in poll_schedule_timeout()

commit 68514dacf2715d11b91ca50d88de047c086fea9c upstream.

A task can end up indefinitely sleeping in do_select() ->
poll_schedule_timeout() when the following race happens:

  TASK1 (thread1)             TASK2                   TASK1 (thread2)
  do_select()
    setup poll_wqueues table
    with 'fd'
                              write data to 'fd'
                                pollwake()
                                  table->triggered = 1
                                                      closes 'fd' thread1 is
                                                        waiting for
    poll_schedule_timeout()
      - sees table->triggered
      table->triggered = 0
      return -EINTR
    loop back in do_select()

But at this point when TASK1 loops back, the fdget() in the setup of
poll_wqueues fails.  So now so we never find 'fd' is ready for reading
and sleep in poll_schedule_timeout() indefinitely.

Treat an fd that got closed as a fd on which some event happened.  This
makes sure cannot block indefinitely in do_select().

Another option would be to return -EBADF in this case but that has a
potential of subtly breaking applications that excercise this behavior
and it happens to work for them.  So returning fd as active seems like a
safer choice.

KVM: x86/mmu: Fix write-protection of PTs mapped by the TDP MMU

commit 7c8a4742c4abe205ec9daf416c9d42fd6b406e8e upstream.

When the TDP MMU is write-protection GFNs for page table protection (as
opposed to for dirty logging, or due to the HVA not being writable), it
checks if the SPTE is already write-protected and if so skips modifying
the SPTE and the TLB flush.

This behavior is incorrect because it fails to check if the SPTE
is write-protected for page table protection, i.e. fails to check
that MMU-writable is '0'.  If the SPTE was write-protected for dirty
logging but not page table protection, the SPTE could locklessly be made
writable, and vCPUs could still be running with writable mappings cached
in their TLB.

Fix this by only skipping setting the SPTE if the SPTE is already
write-protected *and* MMU-writable is already clear.  Technically,
checking only MMU-writable would suffice; a SPTE cannot be writable
without MMU-writable being set.  But check both to be paranoid and
because it arguably yields more readable code.

rcu: Tighten rcu_advance_cbs_nowake() checks

commit 614ddad17f22a22e035e2ea37a04815f50362017 upstream.

Currently, rcu_advance_cbs_nowake() checks that a grace period is in
progress, however, that grace period could end just after the check.
This commit rechecks that a grace period is still in progress while
holding the rcu_node structure's lock.  The grace period cannot end while
the current CPU's rcu_node structure's ->lock is held, thus avoiding
false positives from the WARN_ON_ONCE().

As Daniel Vacek noted, it is not necessary for the rcu_node structure
to have a CPU that has not yet passed through its quiescent state.

drm/i915: Flush TLBs before releasing backing store

commit 7938d61591d33394a21bdd7797a245b65428f44c upstream.

We need to flush TLBs before releasing backing store otherwise userspace
is able to encounter stale entries if a) it is not declaring access to
certain buffers and b) it races with the backing store release from a
such undeclared execution already executing on the GPU in parallel.

The approach taken is to mark any buffer objects which were ever bound
to the GPU and to trigger a serialized TLB flush when their backing
store is released.

Alternatively the flushing could be done on VMA unbind, at which point
we would be able to ascertain whether there is potential a parallel GPU
execution (which could race), but essentially it boils down to paying
the cost of TLB flushes potentially needlessly at VMA unbind time (when
the backing store is not known to be going away so not needed for
safety), versus potentially needlessly at backing store relase time
(since we at that point cannot tell whether there is anything executing
on the GPU which uses that object).

Thereforce simplicity of implementation has been chosen for now with
scope to benchmark and refine later as required.

ath10k: Fix the MTU size on QCA9377 SDIO

commit 09b8cd69edcf2be04a781e1781e98e52a775c9ad upstream.

On an imx6dl-pico-pi board with a QCA9377 SDIO chip, simply trying to
connect via ssh to another machine causes:

[   55.824159] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12
[   55.832169] ath10k_sdio mmc1:0001:1: failed to submit frame: -12
[   55.838529] ath10k_sdio mmc1:0001:1: failed to push frame: -12
[   55.905863] ath10k_sdio mmc1:0001:1: failed to transmit packet, dropping: -12
[   55.913650] ath10k_sdio mmc1:0001:1: failed to submit frame: -12
[   55.919887] ath10k_sdio mmc1:0001:1: failed to push frame: -12

, leading to an ssh connection failure.

One user inspected the size of frames on Wireshark and reported
the followig:

"I was able to narrow the issue down to the mtu. If I set the mtu for
the wlan0 device to 1486 instead of 1500, the issue does not happen.

The size of frames that I see on Wireshark is exactly 1500 after
setting it to 1486."

Clearing the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE avoids the problem and
the ssh command works successfully after that.

Introduce a 'credit_size_workaround' field to ath10k_hw_params for
the QCA9377 SDIO, so that the HI_ACS_FLAGS_ALT_DATA_CREDIT_SIZE
is not set in this case.

Tested with QCA9377 SDIO with firmware WLAN.TF.1.1.1-00061-QCATFSWPZ-1.

mm/hmm.c: allow VM_MIXEDMAP to work with hmm_range_fault

commit 87c01d57fa23de82fff593a7d070933d08755801 upstream.

hmm_range_fault() can be used instead of get_user_pages() for devices
which allow faulting however unlike get_user_pages() it will return an
error when used on a VM_MIXEDMAP range.

To make hmm_range_fault() more closely match get_user_pages() remove
this restriction.  This requires dealing with the !ARCH_HAS_PTE_SPECIAL
case in hmm_vma_handle_pte().  Rather than replicating the logic of
vm_normal_page() call it directly and do a check for the zero pfn
similar to what get_user_pages() currently does.

Also add a test to hmm selftest to verify functionality.

commit d8adf5b92a9d2205620874d498c39923ecea8749 upstream.

dtx_diff suggests to use <(...) syntax to pipe two inputs into it, but
this has never worked: The /proc/self/fds/... paths passed by the shell

but even with this check removed, the function cannot work: hexdump will
eat up the DTB magic, making the subsequent dtc call fail, as a pipe
cannot be rewound.

Simply remove this broken example, as there is already an alternative one

hope this failure is temporary:

We previosuly assumed such modules were powered up in the correct mode,
continuing without further configuration as long as the required power
class was supported by the host.

Restore this behaviour, while preserving the intent of subsequent
patches to avoid the "Address Change Sequence not supported" warning
if we are not going to be accessing the DDM address.
