Queued, thanks (I was on vacation last week).
I am a bit scared about the mode_select_truncated quirk. My reading
of the code is that the MODE SELECT would fail anyway because the
page length does not match in scsi_disk_check_mode_select:
len = m
On ICX-2S2 host, when run L2 guest with both L1/L2 using Icelake-Server-v3
or above, we got below warning:
"warning: host doesn't support requested feature: MSR(10AH).taa-no [bit 8]"
This is because L1 KVM doesn't expose taa-no to L2 if RTM is disabled,
then starting L2 qemu triggers the warning.

In version 4 and anver ATU CR1 has more bits in it than just the
viewport type. Make a guess at masking these out to avoid issues
where Linux writes these bits and fails to enable memory ATUs.

The current Linux driver for this assumes it can write the 255 into
this register and then read back the value to work out how many
viewports are supported.
Clamp the value so that the probe works and does not cause memory
corruption as the value is not well clamped elsewhere in the driver.

As part of a project we have been looking at using the DesignWare
PCIe host. We found a few issues of missing features or small bugs
when using this with a recent Linux kernel (v5.17.x)
Whilst doing this we also made a start on some tracing events.
This is a host to pcie bridge, so use PCI_CLASS_BRIDGE_HOST
for the class.

Previously this series was two separate series:
* Arch section support
Adds the possibility for arch code to add custom section data.
* s390 PV dump support
Adds PV dump data to the custom arch sections.
I've chosen to merge them so it's easier to understand why the arch
section support h
Add a protected dump capability for later feature checking.

Let's move ELF related members into one block and guest memory related

Sometimes dumping a guest from the outside is the only way to get the
data that is needed. This can be the case if a dumping mechanism like
KDUMP hasn't been configured or data needs to be fetched at a specific
point. Dumping a protected guest from the outside without help from
fw/hw doesn't yield
By splitting the writing of the section headers and (future) section
data we prepare for the addition of a string table section and
architecture sections.

The iteration over the memblocks is hard to understand so it's about
time to clean it up.
struct DumpState's next_block and start members can and should be
local variables within the iterator.
Instead of manually grabbing the next memblock we can use
QTAILQ_FOREACH to iterate over all memblocks.
Allocating the header lets us write it at a later time and hence also
allows us to change section and segment table offsets until we
finally write it.

The option generates a lot of warnings for integers casted to pointers,
for example:
/home/pbonzini/work/upstream/qemu/pc-bios/s390-ccw/dasd-ipl.c:174:19: warning:
array subscript 0 is outside array bounds of ‘CcwSeekData[0]’ [-Warray-bounds]

Set current_req to NULL, not current_req->req, to prevent reusing a free'd
buffer in case of repeated SCSI cancel requests. Also apply the fix to
CLEAR QUEUE and BUS DEVICE RESET messages as well, since they also cancel
the request.
