o Tweak the powerpc64 variant a bit. This gets us closer to working
with qemu-system-poewrpc64, but we aren't quite there yet.
Intel NVMe controllers have a slow path for I/Os that span a 128KB stripe boundary but ZFS limits ashift, which is derived from d_stripesize, to 13 (8KB) so we limit the stripesize reported to geom(8) to 4KB.
This may result in a small number of additional I/Os to require splitting in nvme(4), however the NVMe I/O path is very efficient so these additional I/Os will cause very minimal (if any) difference in performance or CPU utilisation.
This can be controller by the new sysctl kern.nvme.max_optimal_sectorsize.

e500mc, e5500, and e6500 all use the normal FPU, with the same behavior as AIM
hardware. e6500 also supports Altivec, so, although we don't yet have e6500
hardware to test on, add these IVORs as well. Theoretically, since it boots the
same as a e5500, it should work, single-threaded, single-core, with full altivec
support as of this commit.
With this commit, and some other patches to be committed shortly FreeBSD now
boots on the P5020, single-core, all the way to user space, and should boot just
fine on e500mc.
Relnotes: Yes (e500mc, e5500 support)

wrong disk could be returned, and higher layers of ZFS would immediately
eject it again.
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev_geom.c:
o When opening by GUID, require both the pool and vdev GUIDs to
match. While it is highly unlikely for two vdevs to have the same
vdev GUIDs, the ZFS storage pool allocator only guarantees they
are unique within a pool.
o Modify the open behavior to:
- If we are opening a vdev that hasn't previously been opened,
open by path without checking GUIDs.
- Otherwise, open by path and verify GUIDs.
- If that fails, search all geom providers for a device with
matching GUIDs.
- If that fails, return ENOENT.

This is (oddly) specified in the ARM Server Base System Architecture. It
extends the GICv2 to support MSI and MSI-X interrupts, however only the
latter are currently supported.
Only the FDT attachment is currently supported, however the attachment
and core driver are split to help adding ACPI support in the future.

without having any lock on the inp. This breaks if the inp
