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.

This should fix the lib32 build since it was not removing the generated
ioctl.c. This file is generated by a find(1) call, so cannot use normal

This allows 'make foo install' or 'make all install'. It is a similar
fix as r304697 did for reading dependency files.

_SKIP_BUILD will be set when nothing is expected to be built. This can
be used to optimize some tree-walks and operations which don't need to
load dependency files or generate dependencies via beforebuild-style
hacks.

This was a mistake in r295641, but is effectively prevented from

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.
These are FreeBSD-specific and were added in r178576 to provide the ability
to pretty-print instances of compound types. However, the print action has
long since been augmented to provide this functionality with a simpler
interface.

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
than MCLBYTES; that is required by A-MSDU / Atheros Fast-Frames

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

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.
