714b7df502 Provide simple mutual exclusion between mount point update and unmount.
Currently mount update keeps vfs_busy(9) reference on the mount point
during MNT_UPDATE VFS_MOUNT() vfsops call.  This already provides the
exclusion, but is problematic for filesystems which need to perform
namei(9) during VFS_MOUNT(MNT_UPDATE) operations, e.g. to refresh
mnt_from path, because namei(9) must not be called while the
vfs_busy(9) reference is owned.

Check for MNT_UPDATE flag before setting MNTK_UNMOUNT, and for
MNTK_UNMOUNT before entering innards of vfs_domount_update(), failing
syscalls with EBUSY if conflict is detected.  Keep vfs_busy(9)
reference around VFS_MOUNT(MNT_UPDATE) calls still to not change VFS
KPI.

In the update path in ffs_mount(), drop vfs_busy() reference around
namei(), which is now safe due to unmount never executing in parallel
with VFS_MOUNT(MNT_UPDATE), and which avoids the deadlock.

3e7ddf02dc Make dpaa work with only slightly modified Linux device trees.
Linux has a slightly different device tree definition for DPAA than originally
done in the FreeBSD driver.  This changes the driver to be mostly compatible
with the Linux device tree definitions.  Currently the differences are:

bman-portals: compatible = "fsl,bman-portals" (Linux is "simple-bus")
qman-portals: compatible = "fsl,qman-portals" (Linux is "simple-bus")
fman: compatible = "fsl,fman" (Linux is "simple-bus")

The Linux device tree doesn't specify anything for rgmii in the mdio.  This
change still requires the device tree to specify the phy-handle, and doesn't yet
support tbi.

ab607f28e3 Don't read if_counters with if_addr_lock held
Calling into an ifnet implementation with the if_addr_lock already
held can cause a LOR and potentially a deadlock, as ifnet
implementations typically can take the if_addr_lock after their
own locks during configuration.  Refactor a sysctl handler that
was violating this to read if_counter data in a temporary buffer
before the if_addr_lock is taken, and then copying the data
in its final location later, when the if_addr_lock is held.

- Increase Rx buffer size from MCLBYTES to MJUMPAGESIZE.
- Provide an additional defragmentation routine for frames larger

support to work with current Tx path implementation.

Enabled features list for RTL8188CE:
- Atheros Fast-Frames;
- A-MPDU (Tx / Rx);
- A-MSDU (Tx / Rx; 4k only);
- Short Guard Interval.

Tested with:
- RTL8188CE (STA+AP) + RTL8821AU (STA).
- RTL8188CE (STA) + RTL8188CUS (AP).

b75f7c6cfb Always call PHYS_TO_VM_PAGE() in is_managed(). Fast road for addresses
under first_page cannot be taken as this variable is connected only to
vm_page_array segment. There could be more segments in system like
the ones for various fictitious page ranges. These can be situated
under vm_page_array segment and so, they could be skipped before this
fix. However, as far as I know, there is no report associated with it.

While here, the return type of this function is changed from boolean_t
to bool type.

a6b91f0f45 Don't place threads on the run queue after waking up other CPUs.
The other CPU might resume and see a still-empty runq and go back to
sleep before sched_add() adds the thread to the runq.  This results
in a lost wakeup and a potential hang if the system is otherwise
completely idle.

The race originated due to a micro-optimization (my fault) in 4BSD in
that it avoided putting a thread on the run queue if the scheduler was
going to preempt to the new thread.  To avoid complexity while fixing
this race, just drop this optimization.  4BSD now always sets the
"owepreempt" flag when a preemption is warranted and defers the actual
preemption to the thread_unlock of the caller the same as ULE.
