Since CPU loops are done as last step in kvm_{insert,remove}_breakpoint()
and kvm_remove_all_breakpoints(), we do not need to distinguish between
invoking CPU and iterated CPUs and can thereby free the identifier for

counting cannot be easily done for such pages in real mode (when
MMU is off) so we added a list of huge pages. It is populated in
virtual mode and get_page is called just once per a huge page.
Real mode handlers check if the
The current VFIO-on-POWER implementation supports only user mode
driven mapping, i.e. QEMU is sending requests to map/unmap pages.
However this approach is really slow, so we want to move that to KVM.
Since H_PUT_TCE can be extremely performance sensitive (especially with
network adapters where
This adds real mode handlers for the H_PUT_TCE_INDIRECT and
H_STUFF_TCE hypercalls for QEMU emulated devices such as IBMVIO
devices or emulated PCI. These calls allow adding multiple entries
(up to 512) into the TCE table in one call which saves time on
transition to/from real mode.
This adds a
This adds hash_for_each_possible_rcu_notrace() which is basically
a notrace clone of hash_for_each_possible_rcu() which cannot be
used in real mode due to its tracing/debugging capability.

VFIO is designed to be used via ioctls on file descriptors
returned by VFIO.
However in some situations support for an external user is required.
The first user is KVM on PPC64 (SPAPR TCE protocol) which is going to
use the existing VFIO groups for exclusive access in real/virtual mode
