Since the patchset ("Build ACPI Heterogeneous Memory Attribute Table (HMAT)"),
HMAT is supported, but only x86 is enabled. Enable HMAT on arm virt machine.

Introduce a new powerpc_excp function specific for BookS CPUs. This
commit copies powerpc_excp_legacy verbatim so the next one has a clean

Since this is now BookS only, we can simplify the code a bit and check
has_hv_mode instead of enumerating the exception models. LPES0 does
not make sense if there is no MSR_HV.
Note that QEMU does not support HV mode on 970 and POWER5+ so we don't

I second that.

Differences from the generic powerpc_excp code:
- Not BookE, so some MSR bits are cleared at interrupt dispatch;
- Always uses HV_EMU if the CPU has MSR_HV;
- Exceptions always delivered in 64 bit.
Exceptions used:
POWERPC_EXCP_ALIGN
POWERPC_EXCP_DECR

This series splits the exception code for BookS CPUs: 970, POWER5+,

back to something more familiar to give everyone a break.
No upfront fixes this time. The pseries code gets used a lot,
