069ea736b5 tcg: Pass the opcode width to target_parse_constraint
This will let us choose how to interpret a given constraint
depending on whether the opcode is 32- or 64-bit.  Which will
let us share more constraint combinations between opcodes.

At the same time, change the interface to return the advanced
pointer instead of passing it in/out by reference.

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.
