that we don't have a good way (yet) to iterate over the mapped pages by
virtual address and simply try each page within the range. Given that we
call pmap_remove() over the entire 2^63 bytes of address space, it takes
a while for pmap_remove to have tried all 2^50 pages.
By using pmap_remove_pages() we use the PV list to find all mappings.

X86: cvtpi2ps is just an SSE instruction with MMX operands. It has no AVX
equivalent.
Give it the right register format so we can also emit it when AVX is enabled.
This should fix a "Cannot select: intrinsic %llvm.x86.sse.cvtpi2ps" fatal error
in clang while building the gnuradio port for amd64.

- Host Identity Protocol (RFC5201)
- Shim6 Protocol (RFC5533)
- 2x experimentation and testing (RFC3692, RFC4727)
This does not indicate interest to implement/support these protocols,
but they are part of the "IPv6 Extension Header Types" [1] based on RFC7045
and might thus be needed by filtering and next header parsing
implementations.

X-Comment: I am not the new maintainer; chime in, it's ours.
When building the system from outside the chroot as part of the release
process, ensure the objdir is within the chroot so that the whole output
of the release.sh script is self-contained in a single directory.
Use CHROOTDIR/tmp/obj instead of CHROOTDIR/usr/obj to minimize possible
interferences with the output of the build itself.

With an unpopulated chroot dir, release building was failing because
the script was attempting to copy resolv.conf into a non-existent /etc
directory of the chroot. Fix this by copying the file only after the
installworld has happened, which will create this directory.

emulation.
The vlapic initialization and cleanup is done via processor specific vmm_ops.
This will allow the VT-x/SVM modules to layer any hardware-assist for APIC
emulation or virtual interrupt delivery on top of the vlapic device model.
Add a parameter to 'vcpu_notify_event()' to distinguish between vlapic
interrupts versus other events (e.g. NMI). This provides an opportunity to
use hardware-assists like Posted Interrupts (VT-x) or doorbell MSR (SVM)
to deliver an interrupt to a guest without causing a VM-exit.
Get rid of lapic_pending_intr() and lapic_intr_accepted() and use the
vlapic_xxx() counterparts directly.
Associate an 'Apic Page' with each vcpu and reference it from the 'vlapic'.
The 'Apic Page' is intended to be referenced from the Intel VMCS as the
'virtual APIC page' or from the AMD VMCB as the 'vAPIC backing page'.

reported to the freebsd-fs mailing list. I believe the problem was
caused by the Readdir operation using VFS_VGET() for a snapshot file entry
instead of VOP_LOOKUP(). This would not occur for NFSv3, since it
will do a VFS_VGET() of "." which fails with ENOTSUPP at the beginning
of the directory, whereas NFSv4 does not check "." or "..". This
patch adds a call to VFS_VGET() for the directory being read to check
for ENOTSUPP.
I also observed that the mount_on_fileid and fsid attributes were
not correct at the snapshot's auto mountpoints when looking at packet
traces for the Readdir. This patch fixes the attributes by doing a check
for different v_mount structure, even if the vnode v_mountedhere is not
set.
