The patch supports RTAS call ibm,errinjct to allow injecting
EEH errors to VFIO PCI devices. The implementation is similiar
to EEH support for VFIO PCI devices: The RTAS request is captured
by QEMU and routed to sPAPRPHBClass::eeh_inject_error() where the
request is translated to VFIO container
The patchset depends on below Linux upstream commits:
commit ed3e81f (powerpc/eeh: Move PE state constants around)
commit ec33d36 (powerpc/eeh: Introduce eeh_pe_inject_err())
According to PAPR specification 2.7, there're 3 RTAS calls relevent to error
injection: ibm,open-errinjct,

This patchset updates target-sparc to use VMStateDescription
rather than hand-written save/load functions. (This and CRIS
are the last two targets still using the old approach.)
It's based on some patches from back in 2012 by Juan which
I've updated, rebased and made some tweaks to.

Convert the SPARC CPU from cpu_load/save functions to VMStateDescription.

There's no need to flush the TLB in the SPARC cpu_load function: we're
guaranteed to be loading state into a fresh clean configuration.

For inbound migration we really want to be able to set the PSR without
having any side effects, but cpu_put_psr() calls cpu_check_irqs() which
might try to deliver CPU interrupts. Split cpu_put_psr() into the
no-side-effect and side-effect parts.
This includes reordering the cpu_check_irqs() to

This is mostly the same with netdev_{add|del} commands.
When we delete the netdev, we also delete the netfilter object

But the idea is that this can be eventually used by other drivers, isn't

Yes, but is is only used for quorum now.
