In HWRM_QUEUE_COS2BW_CFG request, enables field should have the bits
set only for the queue ids which are having the valid parameters.
This causes firmware to return error when the TC to hardware CoS queue
mapping is not 1:1 during DCBNL ETS setup.

The enables bit for VNIC was set wrong when calling the HWRM_FUNC_CFG
firmware call to reserve VNICs. This has the effect that the firmware
will keep a large number of VNICs for the PF, and having very few for
VFs. DPDK driver running on the VFs, which requires more VNICs, may not
work properly as a result.

team's ndo_add_slave() acquires 'team->lock' and later tries to open the
newly enslaved device via dev_open(). This emits a 'NETDEV_UP' event
that causes the VLAN driver to add VLAN 0 on the team device. team's
ndo_vlan_rx_add_vid() will also try to acquire 'team->lock' and
deadlock.
Fix this by checking early at the enslavement function that a team
device is not being enslaved to itself.
A similar check was added to the bond driver in commit 09a89c219baf
("bonding: disallow enslaving a bond to itself").

A reload of the cache's DM table is needed during resize because
otherwise a crash will occur when attempting to access smq policy
entries associated with the portion of the cache that was recently
extended.
The reason is cache-size based data structures in the policy will not be
resized, the only way to safely extend the cache is to allow for a
proper cache policy initialization that occurs when the cache table is
loaded. For example the smq policy's space_init(), init_allocator(),
calc_hotspot_params() must be sized based on the extended cache size.
The fix for this is to disallow cache resizes of this pattern:
1) suspend "cache" target's device
2) resize the fast device used for the cache
3) resume "cache" target's device
Instead, the last step must be a full reload of the cache's DM table.

Commit fd2fa9541 ("dm cache metadata: save in-core policy_hint_size to
on-disk superblock") enabled previously written policy hints to be
used after a cache is reactivated. But in doing so the cache
metadata's hint array was left exposed to out of bounds access because
on resize the metadata's on-disk hint array wasn't ever extended.
Fix this by ignoring that there are no on-disk hints associated with the
newly added cache blocks. An expanded on-disk hint array is later
rewritten upon the next clean shutdown of the cache.

If __device_suspend() runs asynchronously (in which case the device
passed to it is in dpm_suspended_list at that point) and it returns
early on an error or pending wakeup, and the power.direct_complete
flag has been set for the device already, the subsequent
device_resume() will be confused by that and it will call
pm_runtime_enable() incorrectly, as runtime PM has not been
disabled for the device by __device_suspend().
To avoid that, clear power.direct_complete if __device_suspend()
is not going to disable runtime PM for the device before returning.

mlxsw: Couple of fixes
First patch works around an hardware issue in Spectrum-2 where a field
indicating the event type is always set to the same value. Since there
are only two event types and they are reported using different queues,
we can use the queue number to derive the event type.
Second patch prevents a router interface (RIF) leakage when a VLAN
device is deleted from on top a bridge device.

In commit 602b74eda813 ("mlxsw: spectrum_switchdev: Do not leak RIFs

devices were not properly cleaned up when their real device (a bridge)
was removed.
However, I forgot to handle the case of the VLAN device itself being
removed. Do so now when the VLAN device is being unlinked from its real
device.

Due to a hardware issue in Spectrum-2, the field event_type of the event
queue element (EQE) has become reserved. It was used to distinguish between

Use queue number to determine event type, as command interface completion
events are always received on EQ0 and mlxsw driver maps completion events
to EQ1.

In amdgpu_dm_commit_tail(), wait until flip_done() is signaled before
we signal hw_done().
[Why]
This is to temporarily address a paging error that occurs when a
nonblocking commit contends with another commit, particularly in a
mirrored display configuration where at least 2 CRTCs are updated.
The error occurs in drm_atomic_helper_wait_for_flip_done(), when we
attempt to access the contents of new_crtc_state->commit.
Here's the sequence for a mirrored 2 display setup (irrelevant steps
left out for clarity):
**THREAD 1** | **THREAD 2**
|
Initialize atomic state for flip |
|
Queue worker |
...
| Do work for flip
|
| Signal hw_done() on CRTC 1
| Signal hw_done() on CRTC 2
|
| Wait for flip_done() on CRTC 1
<---- **PREEMPTED BY THREAD 1**
Initialize atomic state for cursor |
update (1) |
|
Do cursor update work on both CRTCs |
|
Clear atomic state (2) |
**DONE** |
...
|
| Wait for flip_done() on CRTC 2
| *ERROR*
|
The issue starts with (1). When the atomic state is initialized, the
current CRTC states are duplicated to be the new_crtc_states, and
referenced to be the old_crtc_states. (The new_crtc_states are to be
filled with update data.)
Some things to note:
* Due to the mirrored configuration, the cursor updates on both CRTCs.
* At this point, the pflip IRQ has already been handled, and flip_done
signaled on all CRTCs. The cursor commit can therefore continue.
* The old_crtc_states used by the cursor update are the **same states**
as the new_crtc_states used by the flip worker.
At (2), the old_crtc_state is freed (*), and the cursor commit
completes. We then context switch back to the flip worker, where we
attempt to access the new_crtc_state->commit object. This is
problematic, as this state has already been freed.
(*) Technically, 'state->crtcs[i].state' is freed, which was made to
reference old_crtc_state in drm_atomic_helper_swap_state()
[How]
By moving hw_done() after wait_for_flip_done(), we're guaranteed that
the new_crtc_state (from the flip worker's perspective) still exists.
This is because any other commit will be blocked, waiting for the
hw_done() signal.
Note that both the i915 and imx drivers have this sequence flipped
already, masking this problem.

Commit b5861e5cf2fcf83031ea3e26b0a69d887adf7d21 introduced a check on
the interrupt-window and NMI-window CPU execution controls in order to
inject an external interrupt vmexit before the first guest instruction
executes. However, when APIC virtualization is enabled the host does not
need a vmexit in order to inject an interrupt at the next interrupt window;
instead, it just places the interrupt vector in RVI and the processor will
inject it as soon as possible. Therefore, on machines with APICv it is
not enough to check the CPU execution controls: the same scenario can also
happen if RVI>vPPR.

As of commit 8d860bbeedef ("kvm: vmx: Basic APIC virtualization controls
have three settings"), KVM will disable VIRTUALIZE_APIC_ACCESSES when
a nested guest writes APIC_BASE MSR and kvm-intel.flexpriority=0,
whereas previously KVM would allow a nested guest to enable
VIRTUALIZE_APIC_ACCESSES so long as it's supported in hardware. That is,
KVM now advertises VIRTUALIZE_APIC_ACCESSES to a guest but doesn't
(always) allow setting it when kvm-intel.flexpriority=0, and may even
initially allow the control and then clear it when the nested guest
writes APIC_BASE MSR, which is decidedly odd even if it doesn't cause
functional issues.
Hide the control completely when the module parameter is cleared.

Return early from vmx_set_virtual_apic_mode() if the processor doesn't
support VIRTUALIZE_APIC_ACCESSES or VIRTUALIZE_X2APIC_MODE, both of
which reside in SECONDARY_VM_EXEC_CONTROL. This eliminates warnings
due to VMWRITEs to SECONDARY_VM_EXEC_CONTROL (VMCS field 401e) failing
on processors without secondary exec controls.
Remove the similar check for TPR shadowing as it is incorporated in the
flexpriority_enabled check and the APIC-related code in
vmx_update_msr_bitmap() is further gated by VIRTUALIZE_X2APIC_MODE.

When I added the missing memory outputs, I failed to update the
index of the first argument (ebx) on 32-bit builds, which broke the
fallbacks. Somehow I must have screwed up my testing or gotten
lucky.
Add another test to cover gettimeofday() as well.

Commit 71d29f43b633 ("KVM: PPC: Book3S HV: Don't use compound_order to
determine host mapping size", 2018-09-11) added a call to
__find_linux_pte() and a dereference of the returned PTE pointer to the
radix page fault path in the common case where the page is normal
system memory. Previously, __find_linux_pte() was only called for
mappings to physical addresses which don't have a page struct (e.g.
memory-mapped I/O) or where the page struct is marked as reserved
memory.
This exposes us to the possibility that the returned PTE pointer
could be NULL, for example in the case of a concurrent THP collapse
operation. Dereferencing the returned NULL pointer causes a host
crash.
To fix this, we check for NULL, and if it is NULL, we retry the
operation by returning to the guest, with the expectation that it
will generate the same page fault again (unless of course it has
been fixed up by another CPU in the meantime).

The final call to zlib_deflate(Z_FINISH) may require more output
space to be allocated and so needs to re-invoked. Failure to do so in
the current code leads to incomplete zlib streams (albeit intact due to

capture.

The event subscriptions are added to the subscribed event list while
holding a spinlock, but that lock is subsequently released while still
accessing the subscription object. This makes it possible to unsubscribe
the event --- and freeing the subscription object's memory --- while
the subscription object is simultaneously accessed.
Prevent this by adding a mutex to serialise the event subscription and
unsubscription. This also gives a guarantee to the callback ops that the
add op has returned before the del op is called.
This change also results in making the elems field less special:
subscriptions are only added to the event list once they are fully
initialised.

If CONFIG_WW_MUTEX_SELFTEST=y is enabled, booting an image
in an arm64 virtual machine results in the following
traceback if 8 CPUs are enabled:
DEBUG_LOCKS_WARN_ON(__owner_task(owner) != current)
WARNING: CPU: 2 PID: 537 at kernel/locking/mutex.c:1033 __mutex_unlock_slowpath+0x1a8/0x2e0
...
Call trace:
__mutex_unlock_slowpath()
ww_mutex_unlock()
test_cycle_work()
process_one_work()
worker_thread()
kthread()
ret_from_fork()
If requesting b_mutex fails with -EDEADLK, the error variable
is reassigned to the return value from calling ww_mutex_lock
on a_mutex again. If this call fails, a_mutex is not locked.
It is, however, unconditionally unlocked subsequently, causing
the reported warning. Fix the problem by using two error variables.
With this change, the selftest still fails as follows:
cyclic deadlock not resolved, ret[7/8] = -35
However, the traceback is gone.
