Fix it by:
1) switching to use the new device specific fields per vq
2) not including vhost.c, instead make vhost-test.ko depend on vhost.ko.

I'll do that standalone patch here and give it a spin.

It is necessary for each vcpus system_timestamp memory copy to be
updated from one sample of the nanosecond kernel clock.
If this is not the case, and NTP changes frequency adjustment, different
vcpus will make use of different time bases.

There are several parts to this:
o All registers are 64-bits wide, 32-bit guests use the least

Currently, vhost-net and vhost-scsi are sharing the vhost core code.
However, vhost-scsi shares the code by including the vhost.c file
directly.
Making vhost a separate module makes it is easier to share code with
other vhost devices.

This adds special support for huge pages (16MB). The reference
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 requested
This adds real mode handlers for the H_PUT_TCE_INDIRECT and
H_STUFF_TCE hypercalls for QEMU emulated devices such as virtio
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 g
This allows the host kernel to handle H_PUT_TCE, H_PUT_TCE_INDIRECT

save time on switching to QEMU and back.
Both real and virtual modes are supported - whenever the kernel
fails to handle TCE request, it passes it to the virtual

The current VFIO-on-POWER implementation supports only user mode

The lookup_linux_pte() function returns a linux PTE which is needed in

If we let L1 use EPT, we should probably also support the INVEPT instruction.
In our current nested EPT implementation, when L1 changes its EPT table for

of this modification already calls INVEPT. Therefore, when L1 call

Advertise the support of EPT to the L1 guest, through the appropriate MSR.
