This patch is to add flush parameter for kvm_aga_hva() and move tlb
flush from kvm_mmu_notifier_clear_flush_young() to kvm_age_hva().
kvm_age_hva() can check whether tlb flush is necessary when
return value young is more than 0. Flush tlb if both conditions
are met.

This patch is to use tlb range flush to flush memslot's in the
kvm_vm_ioctl_get/clear_dirty_log() instead of flushing tlbs
of entire ept page table when range flush is available.

Since commit c40dd2f76644 ("powerpc: Add System RAM to /proc/iomem")
it is possible to use the generic walk_system_ram_range() and
the generic page_is_ram().
To enable the use of walk_system_ram_range() by the IBM EHEA
ethernet driver, the generic function has to be exported.
