a369a289ee Modify handling of write to the vlapic SVR register.
The handler is now called after the register value is updated in the virtual
APIC page. This will make it easier to handle APIC-write VM-exits with APIC
register virtualization turned on.

Additionally, mask all the LVT entries when the vlapic is software-disabled.

1aae94ba2c Revert r252694 - which attempted to fix bit emulation for armv6/armv7.
This seems to cause issues with jemalloc + {dhclient, sshd}.

Thus, revert this for now until the root cause can be found and
fixed.

This should quieten some runtime problems with the Raspberry Pi.

150bba5c8f Add an ability to stop gmirror and clear its metadata in one command.
This fixes the problem, when gmirror starts again just after stop.

The problem occurs when gmirror's component has geom label with equal size.
E.g. gpt and gptid have the same size as partition, diskid has the same
size as entire disk. When gmirror's geom has been destroyed, glabel
creates its providers and this initiate retaste.

Now "gmirror destroy" command is available. It destroys geom and also
erases gmirror's metadata.

4a551f35c9 Modify handling of writes to the vlapic ID, LDR and DFR registers.
The handlers are now called after the register value is updated in the virtual
APIC page. This will make it easier to handle APIC-write VM-exits with APIC
register virtualization turned on.

Additionally, we need to ensure that the value of these registers is always
correctly reflected in the virtual APIC page, because there is no VM exit
when the guest reads these registers with APIC register virtualization.

df5d69cc0d For ia64, use pmap_remove_pages() and not pmap_remove(). The problem is
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.

- 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.

0c91ef8145 vlapic code restructuring to make it easy to support hardware-assist for APIC
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'.

12c8434bbd The NFSv4 server would call VOP_SETATTR() with a shared locked vnode
when a Getattr for a file is done by a client other than the one that
holds the file's delegation. This would only happen when delegations
are enabled and the problem is fixed by this patch.

1889cef2a5 An intermittent problem with NFSv4 exporting of ZFS snapshots was
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.
