81fb06cb6b ("remoteproc: Fall back to using parent memory pool if no dedicated available")
breaks i.MX7ULP SD Boot.
i.MX7ULP not use vdevbuffer for communication between Acore and Mcore.
However we still use memory-region for vring. Because we added
"shared-dma-pool" to the resered region, so when vdevbuffer not found,
the memory-region will be used for the virtio data buffer.
So to fix the issue, we could remove "shared-dma-buffer" to avoid
the area to be used to data buffer, then it will still use global
dma area for data buffer.

Resume common flow (System PM / Runtime PM) is like this:
sof_resume
-> specific device resume
-> snd_sof_load_firmware
-> snd_sof_dsp_reset (1)
-> load_modules()
-> snd_sof_run_firmware (2)
We need to implement dsp_reset callback (1) that will actually reset the
DSP but keep it stalled.
In order to implement this we do the following:
-> put DSP into reset (assert CoreReset bit from PWRCTL)
-> stall the DSP using RunStall bit from AudioDSP_REG2 Audiomix
-> take DSP out of reset (de-assert CoreReset bit from PWRCTL)
At this moment the DSP is taken out of reset and Stalled! This means
that we can load the firmware and then start the DSP (2).
Until now we resetted the DSP by turning down the Audiomix PD. This
doesn't work for Runtime PM if another IP is keeping Audiomix PD up.
By introducing dsp_reset() we no longer rely on turning off the audiomix
to reset the DSP.

commit ef3e40a7ea upstream.
When using the PtrAuth feature in a guest, we need to save the host's
keys before allowing the guest to program them. For that, we dump
them in a per-CPU data structure (the so called host context).
But both call sites that do this are in preemptible context,
which may end up in disaster should the vcpu thread get preempted
before reentering the guest.
Instead, save the keys eagerly on each vcpu_load(). This has an
increased overhead, but is at least safe.

commit 0370964dd3 upstream.
On a VHE system, the EL1 state is left in the CPU most of the time,
and only syncronized back to memory when vcpu_put() is called (most
of the time on preemption).
Which means that when injecting an exception, we'd better have a way
to either:
(1) write directly to the EL1 sysregs
(2) synchronize the state back to memory, and do the changes there
For an AArch64, we already do (1), so we are safe. Unfortunately,
doing the same thing for AArch32 would be pretty invasive. Instead,
we can easily implement (2) by calling the put/load architectural
backends, and keep preemption disabled. We can then reload the
state back into EL1.

commit 263c61581a upstream.
Since the switch of floppy driver to blk-mq, the contended (fdc_busy) case
in floppy_queue_rq() is not handled correctly.
In case we reach floppy_queue_rq() with fdc_busy set (i.e. with the floppy
locked due to another request still being in-flight), we put the request
on the list of requests and return BLK_STS_OK to the block core, without
actually scheduling delayed work / doing further processing of the
request. This means that processing of this request is postponed until
another request comes and passess uncontended.
Which in some cases might actually never happen and we keep waiting
indefinitely. The simple testcase is
for i in `seq 1 2000`; do echo -en $i '\r'; blkid --info /dev/fd0 2> /dev/null; done
run in quemu. That reliably causes blkid eventually indefinitely hanging
in __floppy_read_block_0() waiting for completion, as the BIO callback
never happens, and no further IO is ever submitted on the (non-existent)
floppy device. This was observed reliably on qemu-emulated device.
Fix that by not queuing the request in the contended case, and return
BLK_STS_RESOURCE instead, so that blk core handles the request
rescheduling and let it pass properly non-contended later.
