commit bb83d5fb55 upstream.
The pch_get_backlight(), lpt_get_backlight(), and lpt_set_backlight()
functions operate directly on the hardware registers. If inverting the
value is needed, using intel_panel_compute_brightness(), it should only
be done in the interface between hardware registers and
panel->backlight.level.
The CPU mode takeover code added in commit 5b1ec9ac7a
("drm/i915/backlight: Fix backlight takeover on LPT, v3.") reads the
hardware register and converts to panel->backlight.level correctly,
however the value written back should remain in the hardware register
"domain".
This hasn't been an issue, because GM45 machines are the only known
users of i915.invert_brightness and the brightness invert quirk, and
without one of them no conversion is made. It's likely nobody's ever hit
the problem.

commit ad0a6bad44 upstream.
We've observed crashes due to an empty cpu mask in
hyperv_flush_tlb_others. Obviously the cpu mask in question is changed
between the cpumask_empty call at the beginning of the function and when
it is actually used later.
One theory is that an interrupt comes in between and a code path ends up
changing the mask. Move the check after interrupt has been disabled to
see if it fixes the issue.

commit 5c6679b5cb upstream.
A widget's "dirty" list_head, much like its "list" list_head, eventually
chains back to a list_head on the snd_soc_card itself. This means that
the list can stick around even after the widget (or all widgets) have
been freed. Currently, however, widgets that are in the dirty list when
freed remain there, corrupting the entire list and leading to memory
errors and undefined behavior when the list is next accessed or
modified.
I encountered this issue when a component failed to probe relatively
late in snd_soc_bind_card(), causing it to bail out and call
soc_cleanup_card_resources(), which eventually called
snd_soc_dapm_free() with widgets that were still dirty from when they'd
been added.

[BUG]
There are several bug reports about recent kernel unable to relocate
certain data block groups.
Sometimes the error just goes away, but there is one reporter who can
reproduce it reliably.
The dmesg would look like:
[438.260483] BTRFS info (device dm-10): balance: start -dvrange=34625344765952..34625344765953
[438.269018] BTRFS info (device dm-10): relocating block group 34625344765952 flags data|raid1
[450.439609] BTRFS info (device dm-10): found 167 extents, stage: move data extents
[463.501781] BTRFS info (device dm-10): balance: ended with status: -2
[CAUSE]
The ENOENT error is returned from the following call chain:
add_data_references()
|- delete_v1_space_cache();
|- if (!found)
return -ENOENT;
The variable @found is set to true if we find a data extent whose
disk bytenr matches parameter @data_bytes.
With extra debugging, the offending tree block looks like this:
leaf bytenr = 42676709441536, data_bytenr = 34626327621632
ctime 1567904822.739884119 (2019-09-08 03:07:02)

uuid d0d4361f-d231-6d40-8901-fe506e4b2b53
Although item 27 has disk bytenr 34626327621632, which matches the
data_bytenr, its type is prealloc, not reg.
This makes the existing code skip that item, and return ENOENT.
[FIX]
The code is modified in commit 19b546d7a1 ("btrfs: relocation: Use
btrfs_find_all_leafs to locate data extent parent tree leaves"), before
that commit, we use something like
"if (type == BTRFS_FILE_EXTENT_INLINE) continue;"
But in that offending commit, we use (type == BTRFS_FILE_EXTENT_REG),
ignoring BTRFS_FILE_EXTENT_PREALLOC.
Fix it by also checking BTRFS_FILE_EXTENT_PREALLOC.

commit b1b95cb5c0 upstream.
Rollback the reservation in the completion ring when we get a
NETDEV_TX_BUSY. When this error is received from the driver, we are
supposed to let the user application retry the transmit again. And in
order to do this, we need to roll back the failed send so it can be
retried. Unfortunately, we did not cancel the reservation we had made
in the completion ring. By not doing this, we actually make the
completion ring one entry smaller per NETDEV_TX_BUSY error we get, and
after enough of these errors the completion ring will be of size zero
and transmit will stop working.
Fix this by cancelling the reservation when we get a NETDEV_TX_BUSY
error.

commit f09ced4053 upstream.
Fix a race when multiple sockets are simultaneously calling sendto()
when the completion ring is shared in the SKB case. This is the case
when you share the same netdev and queue id through the
XDP_SHARED_UMEM bind flag. The problem is that multiple processes can
be in xsk_generic_xmit() and call the backpressure mechanism in
xskq_prod_reserve(xs->pool->cq). As this is a shared resource in this
specific scenario, a race might occur since the rings are
single-producer single-consumer.
Fix this by moving the tx_completion_lock from the socket to the pool
as the pool is shared between the sockets that share the completion
ring. (The pool is not shared when this is not the case.) And then
protect the accesses to xskq_prod_reserve() with this lock. The
tx_completion_lock is renamed cq_lock to better reflect that it
protects accesses to the potentially shared completion ring.

commit 2a5f1b67ec upstream.
We reset the guest's view of PMCR_EL0 unconditionally, based on
the host's view of this register. It is however legal for an
implementation not to provide any PMU, resulting in an UNDEF.
The obvious fix is to skip the reset of this shadow register
when no PMU is available, sidestepping the issue entirely.
If no PMU is available, the guest is not able to request
a virtual PMU anyway, so not doing nothing is the right thing
to do!
It is unlikely that this bug can hit any HW implementation
though, as they all provide a PMU. It has been found using nested
virt with the host KVM not implementing the PMU itself.

commit 5c11f7d9f8 upstream.
We may send a request (with or without its data) from two paths:
1. From our I/O context nvme_tcp_io_work which is triggered from:
- queue_rq
- r2t reception
- socket data_ready and write_space callbacks
2. Directly from queue_rq if the send_list is empty (because we want to
save the context switch associated with scheduling our io_work).
However, given that now we have the send_mutex, we may run into a race
condition where none of these contexts will send the pending payload to
the controller. Both io_work send path and queue_rq send path
opportunistically attempt to acquire the send_mutex however queue_rq only
attempts to send a single request, and if io_work context fails to
acquire the send_mutex it will complete without rescheduling itself.
The race can trigger with the following sequence:
1. queue_rq sends request (no incapsule data) and blocks
2. RX path receives r2t - prepares data PDU to send, adds h2cdata PDU
to the send_list and schedules io_work
3. io_work triggers and cannot acquire the send_mutex - because of (1),
ends without self rescheduling
4. queue_rq completes the send, and completes
==> no context will send the h2cdata - timeout.
Fix this by having queue_rq sending as much as it can from the send_list
such that if it still has any left, its because the socket buffer is
full and the socket write_space callback will trigger, thus guaranteeing
that a context will be scheduled to send the h2cdata PDU.

commit 095507dc13 upstream.
Systems configured with CONFIG_ZONE_DMA32, CONFIG_ZONE_NORMAL and
!CONFIG_ZONE_DMA will fail to properly setup ARCH_LOW_ADDRESS_LIMIT. The
limit will default to ~0ULL, effectively spanning the whole memory,
which is too high for a configuration that expects low memory to be
capped at 4GB.
Fix ARCH_LOW_ADDRESS_LIMIT by falling back to arm64_dma32_phys_limit
when arm64_dma_phys_limit isn't set. arm64_dma32_phys_limit will honour
CONFIG_ZONE_DMA32, or span the entire memory when not enabled.
Fixes: 1a8e1cef76 ("arm64: use both ZONE_DMA and ZONE_DMA32")
