pseries: fix kvmppc_set_fwnmi()

QEMU issues the ioctl(KVM_CAP_PPC_FWNMI) on the first vCPU.

If the first vCPU is currently running, the vCPU mutex is held
and the ioctl() cannot be done and waits until the mutex is released.
This never happens and the VM is stuck.

To avoid this deadlock, issue the ioctl on the same vCPU doing the
RTAS call.

The problem can be reproduced by booting a guest with several vCPUs
(the probability to have the problem is (n - 1) / n, n = # of CPUs),
and then by triggering a kernel crash with "echo c >/proc/sysrq-trigger".

On the reboot, the kernel hangs after:

ppc/spapr: Move GPRs setup to one place

At the moment "pseries" starts in SLOF which only expects the FDT blob
pointer in r3. As we are going to introduce a OpenFirmware support in
QEMU, we will be booting OF clients directly and these expect a stack
pointer in r1, Linux looks at r3/r4 for the initramdisk location
(although vmlinux can find this from the device tree but zImage from
distro kernels cannot).

This extends spapr_cpu_set_entry_state() to take more registers. This
should cause no behavioral change.

firmware
* Add TCG emulation of the msgsndp etc. supervisor privileged
doorbell instructions
* Allow "pnv" machine type to run Hostboot style firmwares
* Add a virtual TPM device for spapr machines
* Implement devices for POWER8 PHB3 and POWER9 PHB4 host bridges for
the pnv machine type
* Use faster Spectre mitigation by default for POWER9 DD2.3 machines
* Introduce Firmware Assisted NMI dump facility for spapr machines
* Fix a performance regression with load/store multiple instructions
in TCG

as well as some other assorted cleanups and fixes.

ppc: spapr: Handle "ibm,nmi-register" and "ibm,nmi-interlock" RTAS calls

This patch adds support in QEMU to handle "ibm,nmi-register"
and "ibm,nmi-interlock" RTAS calls.

The machine check notification address is saved when the
OS issues "ibm,nmi-register" RTAS call.

This patch also handles the case when multiple processors
experience machine check at or about the same time by
handling "ibm,nmi-interlock" call. In such cases, as per
PAPR, subsequent processors serialize waiting for the first
processor to issue the "ibm,nmi-interlock" call. The second
processor that also received a machine check error waits
till the first processor is done reading the error log.
The first processor issues "ibm,nmi-interlock" call
when the error log is consumed.

target/ppc: Build rtas error log upon an MCE

Upon a machine check exception (MCE) in a guest address space,
KVM causes a guest exit to enable QEMU to build and pass the
error to the guest in the PAPR defined rtas error log format.

This patch builds the rtas error log, copies it to the rtas_addr
and then invokes the guest registered machine check handler. The
handler in the guest takes suitable action(s) depending on the type
and criticality of the error. For example, if an error is
unrecoverable memory corruption in an application inside the
guest, then the guest kernel sends a SIGBUS to the application.
For recoverable errors, the guest performs recovery actions and
logs the error.

ppc patch queue 2019-10-04

Here's the next batch of ppc and spapr patches. Includes:
* Fist part of a large cleanup to irq infrastructure
* Recreate the full FDT at CAS time, instead of making a difficult
to follow set of updates. This will help us move towards
eliminating CAS reboots altogether
* No longer provide RTAS blob to SLOF - SLOF can include it just as
well itself, since guests will generally need to relocate it with
a call to instantiate-rtas
* A number of DFP fixes and cleanups from Mark Cave-Ayland
* Assorted bugfixes
* Several new small devices for powernv
