I encounter this when trying to stress the async page fault in L1 guest w/
L2 guests running.
Commit 9b132fbe5419 (Add rcu user eqs exception hooks for async page
fault) adds rcu_irq_enter/exit() to kvm_async_pf_task_wait() to exit cpu
idle eqs when needed, to protect the code that needs use rcu. However,
we need to call the pair even if the function calls schedule(), as seen
from the above backtrace.
This patch fixes it by informing the RCU subsystem exit/enter the irq
towards/away from idle for both n.halted and !n.halted.

There are three issues in nested_vmx_check_exception:
1) it is not taking PFEC_MATCH/PFEC_MASK into account, as reported
by Wanpeng Li;
2) it should rebuild the interruption info and exit qualification fields
from scratch, as reported by Jim Mattson, because the values from the
L2->L0 vmexit may be invalid (e.g. if an emulated instruction causes
a page fault, the EPT misconfig's exit qualification is incorrect).
3) CR2 and DR6 should not be written for exception intercept vmexits
(CR2 only for AMD).
This patch fixes the first two and adds a comment about the last,
outlining the fix.

We recently added an integer overflow check but it needs an additional
tweak to work properly on 32 bit systems.
The problem is that we're doing the right hand side of the assignment as
type unsigned long so the max it will have an integer overflow instead
of being larger than SIZE_MAX. That means the "sz > SIZE_MAX" condition
is never true even on 32 bit systems. We need to first cast it to u64
and then do the math.

Do this in the caller of nested_vmx_vmexit instead.
nested_vmx_check_exception was doing a vmwrite to the vmcs02's
VM_EXIT_INTR_ERROR_CODE field, so that prepare_vmcs12 would move
the field to vmcs12->vm_exit_intr_error_code. However that isn't
possible on pre-Haswell machines. Moving the vmcs12 write to the
callers fixes it.

After the link tests, there is a race on one side of the test for
the link coming up. It's possible, in some cases, for the test script
to write to the 'peer_trans' files before the link has come up.
To fix this, we simply use the link event file to ensure both sides

It seems that under certain scenarios the SPAD can have bogus values caused
by an agent (i.e. BIOS or other software) that is not the kernel driver, and
that causes memory window setup failure. This should not cause the link to
be disabled because if we do that, the driver will never recover again. We
have verified in testing that this issue happens and prevents proper link
recovery.

Fix inconsistent use of of_graph_get_port_parent() where
asoc_simple_card_parse_graph_dai() does of_node_get() before
calling it while other callers do not. We can fix this by
not trashing the node passed to of_graph_get_port_parent().
Let's also make sure the callers have correct refcounts and remove
related incorrect of_node_put() calls for of_for_each_phandle
as that's done by of_phandle_iterator_next() except when
we break out of the loop early.
Let's fix both issues with a single patch to avoid kobject
refcounts getting messed up more if two patches are merged
separately.
Otherwise strange issues can happen caused by memory corruption
caused by too many kobject_del() calls such as:

The HPET resume path abuses irq_domain_[de]activate_irq() to restore the
MSI message in the HPET chip for the boot CPU on resume and it relies on an
implementation detail of the interrupt core code, which magically makes the
HPET unmask call invoked via a irq_disable/enable pair. This worked as long
as the irq code did unconditionally invoke the unmask() callback. With the
recent changes which keep track of the masked state to avoid expensive
hardware access, this does not longer work. As a consequence the HPET timer
interrupts are not unmasked which breaks resume as the boot CPU waits
forever that a timer interrupt arrives.
Make the restore of the MSI message explicit and invoke the unmask()
function directly. While at it get rid of the pointless affinity setting as
nothing can change the affinity of the interrupt and the vector across
suspend/resume. The restore of the MSI message reestablishes the previous
affinity setting which is the correct one.
