PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache. We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead
of "[id]-cache-block-size" (note the extra hyphen).
We were also missing some of the required cache properties. This
patch adds the [id]-cache-line-size properties (which have the same
values as the block size properties in all current cases). We also
add the [id]-cache-size properties.
Adding the cache sizes requires some extra infrastructure in the
general target-ppc code to (optionally) set the cache sizes for
various CPUs. The CPU family descriptions in translate_init.c can set
these sizes - this patch adds correct information for POWER7, I'm
leaving other CPU types to people who have a physical example to
verify against. In addition, for -cpu host we take the values
advertised by the host (if available) and use those to override the
information based on PVR.

On -M mac99, we can run 970 CPUs. However, these CPUs define the initial
instruction pointer they start execution at as part of their bootup protocol,
so effectively it's up to the board to decide where they start.
This went unnoticed, because they used to boot at the same location our flash
was mapped to, but due to the recent reset changes our 970 CPUs want to reset
to 0x100 now, which is always a 0 instruction.
Set the initial IP to something reasonable for -M mac99.

(KVM_EXIT_WATCHDOG) handling is added.
Watchdog state machine is cleared whenever VM state changes to running.

This value is not needed if we use correctly the MSR[IP] bit.
excp_prefix is always 0x00000000, except when the MSR[IP] bit is
implemented and set to 1, in that case excp_prefix is 0xfff00000.
The handling of MSR[IP] was already implemented but not used at reset
because the value of env->msr was changed "manually".
The patch uses the function hreg_store_msr() to set env->msr, this
ensures a good handling of MSR[IP] at reset, and therefore a good value
for excp_prefix.

If a guest neglected to register (secondary) indicators but still runs
with notifications enabled, we might end up writing to guest zero;
avoid this by checking for valid indicators and only writing to the
guest and generating an interrupt if indicators have been setup.

Use of a flash memory device for the BIOS was added in series "[PATCH
v10 0/8] PC system flash support", commit 4732dca..1b89faf, v1.1.
Flash vs. ROM is a guest-visible difference. Thus, flash use had to
be suppressed for machine types pc-1.0 and older. This was
accomplished by adding a dummy device "pc-sysfw" with property
"rom_only":
* Non-zero rom_only means "use ROM". Default for pc-1.0 and older.
* Zero rom_only means "maybe use flash". Default for newer machines.
Not only is the dummy device ugly, it was also retroactively added to
the older machine types! Fortunately, it's not guest-visible (thus no
immediate guest ABI breakage), and has no vmstate (thus no immediate
migration breakage). Breakage occurs only if the user unwisely
enables flash by setting rom_only to zero. Patch review FAIL #1.
Why "maybe use flash"? Flash didn't (and still doesn't) work with
KVM. Therefore, rom_only=0 really means "use flash, except when KVM
is enabled, use ROM". This is a Bad Idea, because it makes enabling/
disabling KVM guest-visible. Patch review FAIL #2.
Aside: it also precludes migrating between KVM on and off, but that's
not possible for other reasons anyway.
Fix as follows:
1. Change the meaning of rom_only=0 to mean "use flash, no ifs, buts,
or maybes" for pc-i440fx-1.5 and pc-q35-1.5. Don't change anything
for older machines (to remain bug-compatible).
2. Change the default value from 0 to 1 for these machines.
Necessary, because 0 doesn't work with KVM. Once it does, we can flip
the default back to 0.
3. Don't revert the retroactive addition of device "pc-sysfw" to older
machine types. Seems not worth the trouble.
4. Add a TODO comment asking for device "pc-sysfw" to be dropped once
flash works with KVM.
Net effect is that you get a BIOS ROM again even when KVM is disabled,
just like for machines predating the introduction of flash.
To get flash instead, use "--global pc-sysfw.rom_only=0".
