check in power7_nap() added code that prevents even cores which enter sleep

I have a machine on which 3.15 usually fails to boot, and 3.14 boots
every time. The machine is a POWER8 2-socket server with 20 cores
(thus 160 CPUs), 128GB of RAM, and 7 SCSI disks connected via a
hardware-RAID-capable adapter which appears as two IPR controllers
which are both connected to

Yeah sorry. I started looking at this and got dragged into another mess.
You seem to have duplicated the functionality of arch_deref_entry_point(),
which was also added for kprobes, and for the same reason - ie. because some

Tlb search operation used for victim hint relies on the default tlb set by the
host. When hardware tablewalk support is enabled in the host, the default tlb is
TLB1 which leads KVM to evict the bolted entry. Set and restore the default tlb
when searching for victim hint.

For FSL e6500 core the kernel uses power management SPR register (PWRMGTCR0)
to enable idle power down for cores and devices by setting up the idle count
period at boot time. With the host already controlling the power management
configuration the guest could simply benefit from it, so emulate

Add KVM Book3E AltiVec support and enable e6500 core.
Integrates Paul's FP/VMX/VSX changes that landed in kvm-ppc-queue in January
and take into account feedback.
Mihai Caraman (6):
KVM: PPC: Book3E: Use common defines for SPE/FP/AltiVec int numbers
KVM: PPC: Book3E: Refactor SPE/FP exit
SPE/FP/AltiVec interrupts share the same numbers. Refactor SPE/FP exit handling
to accommodate AltiVec later on the same flow. Add kvmppc_supports_spe() to
detect
suport for the unit at runtime since it can be configured in the kernel but not
featured on hardware and vice versa.

Use common BOOKE_IRQPRIO and BOOKE_INTERRUPT defines for SPE/FP/AltiVec
which share the same interrupt numbers.

Increase FPU laziness by calling kvmppc_load_guest_fp() just before
returning to guest instead of each sched in. Without this improvement
an interrupt may also claim floting point corrupting guest state.
