When requesting a size which cannot be read, the error message shows
a different address which is misleading to the user and it looks like
something's wrong with the address parsing. This is because the input
@addr variable is incremented in the memory dumping loop:

(qemu) memsave 0xffffffff8418069c 0xb00000 mem
Invalid addr 0xffffffff849ffe9c specified

Fix that by saving the original address and size and use them in the
error message:

(qemu) memsave 0xffffffff8418069c 0xb00000 mem
Invalid addr 0xffffffff8418069c/size 11534336 specified

The emulation for EEH RTAS requests from guest isn't covered
by QEMU yet and the patch implements them.

The patch defines constants used by EEH RTAS calls and adds
callbacks sPAPRPHBClass::{eeh_set_option, eeh_get_state, eeh_reset,
eeh_configure}, which are going to be used as follows:

  * RTAS calls are received in spapr_pci.c, sanity check is done
    there.
  * RTAS handlers handle what they can. If there is something it
    cannot handle and the corresponding sPAPRPHBClass callback is
    defined, it is called.
  * Those callbacks are only implemented for VFIO now. They do ioctl()
    to the IOMMU container fd to complete the calls. Error codes from
    that ioctl() are transferred back to the guest.

5b79b1ca "target-ppc: Create versionless CPU class per family if KVM" added
a dynamic CPU class registration with the name of the CPU family which
QEMU is running on. For example, this allowed specifying "-cpu POWER7"
on every version of POWER7 machine, not just the one which POWER7 was
an alias of. I.e. before 5b79b1ca, "-cpu POWER7" would not work on real
POWER7 2.1 and would work on POWER7 2.3 only. The same story for POWER8.

However that patch broke POWER5+ support as POWER5+ CPU uses the same
name as the CPU class so dynamic registering of the POWER5+ class failed.

This redefines POWER5+ server CPUs by adding a version to them and adding
an alias for TCG case. KVM will use dynamically registered CPUs.

While we are here, do the same for 970 CPU.

This patch adds basic support for the VTB.

PowerISA:
The Virtual Time Base (VTB) is a 64-bit incrementing counter.
Virtual Time Base increments at the same rate as the Time Base until its value
becomes 0xFFFF_FFFF_FFFF_FFFF (2 64 - 1); at the next increment its value
becomes 0x0000_0000_0000_0000. There is no interrupt or other indication when
this occurs.

The operation of the Virtual Time Base has the following additional
properties.
1. Loading a GPR from the Virtual Time Base has no effect on the accuracy of
the Virtual Time Base.
2. Copying the contents of a GPR to the Virtual Time Base replaces the
contents of the Virtual Time Base with the contents of the GPR.

Since env->msr has already been restored by the time cpu_post_load is called,
make sure that ppc_store_msr() is explicitly called with all msr bits except
MSR_TGPR marked as invalid.

This solves the issue where MSR flags aren't set correctly when restoring a VM
snapshot, in particular the internal env->excp_prefix value when MSR_EP has
been altered by a guest.
