Since arm_hcr_el2_eff includes a check against
arm_is_secure_below_el3, we can often remove a
nearby check against secure state.
In some cases, sort the call to arm_hcr_el2_eff
to the end of a short-circuit logical sequence.

Architecturally, it's possible for an AArch64 machine to have
all of its RAM over the 4GB mark, but our kernel/initrd loading
code in boot.c assumes that the upper half of the addresses
to load these images to is always zero. Write the whole 64 bit
address into the bootloader code fragment, not just the low half.
Note that, currently, none of the existing QEMU machines have
their main memory over 4GBs, so this was not a user-visible bug.

Taking the address of a field in a packed struct is a bad idea, because
it might not be actually aligned enough for that pointer type (and
thus cause a crash on dereference on some host architectures). Newer
versions of clang warn about this. Avoid the bug by not using the
"modify in place" byte swapping functions.
Patch produced with scripts/coccinelle/inplace-byteswaps.cocci

Just like on other architectures, we should stop the clock while the guest
is not running. This is already properly done for TCG. Right now, doing an
offline migration (stop, migrate, cont) can easily trigger stalls in the
guest.
Even doing a
(hmp) stop
... wait 2 minutes ...
(hmp) cont
will already trigger stalls.
So whenever the guest stops, backup the KVM TOD. When continuing to run
the guest, restore the KVM TOD.
One special case is starting a simple VM: Reading the TOD from KVM to
stop it right away until the guest is actually started means that the
time of any simple VM will already differ to the host time. We can
simply leave the TOD running and the guest won't be able to recognize
it.
For migration, we actually want to keep the TOD stopped until really
starting the guest. To be able to catch most errors, we should however
try to set the TOD in addition to simply storing it. So we can still
catch basic migration problems.
If anything goes wrong while backing up/restoring the TOD, we have to
ignore it (but print a warning). This is then basically a fallback to
old behavior (TOD remains running).
I tested this very basically with an initrd:
1. Start a simple VM. Observed that the TOD is kept running. Old
behavior.
2. Ordinary live migration. Observed that the TOD is temporarily
stopped on the destination when setting the new value and
correctly started when finally starting the guest.
3. Offline live migration. (stop, migrate, cont). Observed that the
TOD will be stopped on the source with the "stop" command. On the
destination, the TOD is temporarily stopped when setting the new
value and correctly started when finally starting the guest via
"cont".
4. Simple stop/cont correctly stops/starts the TOD. (multiple stops
or conts in a row have no effect, so works as expected)
In the future, we might want to send the guest a special kind of time sync
interrupt under some conditions, so it can synchronize its tod to the
host tod. This is interesting for migration scenarios but also when we
get time sync interrupts ourselves. This however will most probably have
to be handled in KVM (e.g. when the tods differ too much) and is not
desired e.g. when debugging the guest (single stepping should not
result in permanent time syncs). I consider something like that an add-on
on top of this basic "don't break the guest" handling.

The STIBP flag may be supported by the host KVM module, so QEMU
can allow it to be configured manually, and it can be exposed to
guests when using "-cpu host".
No additional migration code is required because the whole
contents of spec_ctrl is already migrated in the "cpu/spec_ctrl"
section.
Corresponding KVM patch was submitted at:
