80db0e7822 memhp: don't generate memory hotplug AML if it's not enabled/supported
That reduces DSDT by 910 bytes when memory hotplug
isn't enabled.

While doing so drop intermediate variables/arguments
passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making
it local to memory_hotplug.c, hardcoding it there as
it can't change.

Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through
intermediate variables/arguments where it's not needed.
Instead initialize in module static variable when MMIO
region is mapped and use that within memory_hotplug.c
whenever it's required.
That way MMIO base specified only at one place and AML
with MMIO would always use the same value.

https://bugzilla.redhat.com/show_bug.cgi?id=1295637
Upon set_link monitor command or upon netdev deletion
virtio-net sends link down indication to the guest
and stops vhost if one is used.
Guest driver can still submit data for TX until it
recognizes link loss. If these packets not returned by
the host, the Windows guest will never be able to finish
disable/removal/shutdown.
Now each packet sent by guest after NIC indicated link
down will be completed immediately.

02ed3e7c16 virtio-crypto: zeroize the key material before free
Common practice with sensitive information (key material, passwords,
etc). Prevents sensitive information from being exposed by accident later in
coredumps, memory disclosure bugs when heap memory is reused, etc.

Sensitive information is sometimes also held in mlocked pages to prevent
it being swapped to disk but that's not being done here.

Let's zeroize the memory of CryptoDevBackendSymOpInfo structure pointed
for key material security.

8607f5c307 virtio: convert to use DMA api
Currently, all virtio devices bypass IOMMU completely. This is because
address_space_memory is assumed and used during DMA emulation. This
patch converts the virtio core API to use DMA API. This idea is

- introducing a new transport specific helper to query the dma address
  space. (only pci version is implemented).
- query and use this address space during virtio device guest memory
  accessing when iommu platform (VIRTIO_F_IOMMU_PLATFORM) was enabled
  for this device.

556899fc19 hw/ssi/imx_spi.c: Remove MSGDATA register support
From the documentation it is not clear what this SPI register is about.

Moreover, neither linux driver nor xvisor driver are using this SPI register.

For now we just remove it and issue a log on register write access.

24cb2e0d57 m25p80: don't let rogue SPI controllers cause buffer overruns
In normal operation we should never attempt to put more
data into the data[] array than it can hold. However if the
SPI controller connected to us misbehaves then it can send
us a sequence of commands that attempt this. Since the
controller might be in the guest (if the hardware does SPI
via bit-banging), catch the possible overrun conditions and
reset the flash internal state, logging them as guest errors.
