commit 6398326b9ba1("KVM: PPC: Book3S HV P9: Stop using vc->dpdes")
introduced an optimization to use only vcpu->doorbell_request for SMT
emulation for Power9 and above guests, but the code for nested guests
still relies on the old way of handling doorbells, due to which an L2
guest cannot be boot
This reverts commit 7c3ded5735141ff4d049747c9f76672a8b737c49.
On PowerNV, when a nested guest tries to use a feature prohibited by
HFSCR, the nested hypervisor (L1) should get a H_FAC_UNAVAILABLE trap
and then L1 can emulate the feature. But with the change introduced by
commit 7c3ded573514 ("KVM:
Doorbell emulation for nested KVM guests in V1 API is broken because of
2 reasons:
1. L0 presenting H_EMUL_ASSIST to L1 instead of H_FAC_UNAVAIL
2. Broken plumbing for passing around doorbell state.
Fix the trap passed to L1 and the plumbing for maintaining doorbell
state.

The EDAC drivers locally maintaining a statically defined

When del_timer_sync() is called in an interrupt context it throws a warning
because of potential deadlock. The timer is used only to exit from
wait_for_completion() after a timeout so replacing the call with
wait_for_completion_timeout() allows to remove the problematic timer and
its related functi

Hello,
This is the v6 of the series of patches aiming to make the machine
driver `fsl-asoc-card` compatible with S/PDIF controllers on imx boards.
The main goal is to allow the use of S/PDIF controllers with ASRC
modules.
