Add one to esel values in h2g_tlb1_rmap, so that no mapping can be
distinguished from esel 0. Note that we're not saved by the fact
that host esel 0 is reserved for non-KVM use, because KVM host esel
numbering is not the raw host numbering (see to_htlb1_esel).

Commit 523f0e5421c12610527c620b983b443f329e3a32 (KVM: PPC: E500:
Explicitly mark shadow maps invalid) began using E500_TLB_VALID
for guest TLB1 entries, and skipping invalidations if it's not set.
However, when E500_TLB_VALID was set for such entries, it was on a
fake local ref, and so the
It's possible that we're using the same host TLB1 slot to map (a
presumably different portion of) the same guest TLB1 entry. Clear
the bit in the map before setting it, so that if the esels are the same
the bit will remain set.

Remove braces that Linux style doesn't permit, remove space after
'*' that Lindent added, keep error/debug strings contiguous, etc.

Currently, devices that are emulated inside KVM are configured in a
hardcoded manner based on an assumption that any given architecture
only has one way to do it. If there's any need to access device state,
it is done through inflexible one-purpose-only IOCTLs (e.g.
KVM_GET/SET_LAPIC). Defining
This is QEMU's hw/openpic.c from commit
abd8d4a4d6dfea7ddea72f095f993e1de941614e (Update version for
1.4.0-rc0), run through Lindent with no other changes to ease merging
future changes between Linux and QEMU. Remaining style issues
(including those introduced by Lindent) will be fixed in a later
Remove some parts of the code that are obviously QEMU or Raven specific
before fixing style issues, to reduce the style issues that need to be
fixed.

This will be used by the in-kernel MPIC to update its per-vcpu data
structures, and other vcpu init actions may benefit from migrating to
this over fixed initialization.
The notifier itself is kept in the non-arch-specific struct, and
initialized from non-arch-specific code. I was hoping to make
