return success if the passed vnode pointer is NULL (rather than
panicking). This can occur if either audit or accounting are
disabled while the policy is running.
Since the swapoff control has no real relevance to this policy,
which is concerned about intent to write rather than water under the
bridge, remove it.

spurious optimizations. gcc doesn't support FENV_ACCESS, so when it
folds constants, it assumes that the rounding mode is always the
default and floating point exceptions never matter.
processes are not producing absolute pathname tokens. It is required
that audited pathnames are generated relative to the global root mount
point. This modification changes our implementation of audit_canon_path(9)
and introduces a new function: vn_fullpath_global(9) which performs a
vnode -> pathname translation relative to the global mount point based
on the contents of the name cache. Much like vn_fullpath,
vn_fullpath_global is a wrapper function which called vn_fullpath1.
Further, the string parsing routines have been converted to use the
sbuf(9) framework. This change also removes the conditional acquisition
of Giant, since the vn_fullpath1 method will not dip into file system
dependent code.
The vnode locking was modified to use vhold()/vdrop() instead the vref()
and vrele(). This will modify the hold count instead of modifying the
user count. This makes more sense since it's the kernel that requires
the reference to the vnode. This also makes sure that the vnode does not
get recycled we hold the reference to it. [1]

in EITHER/OR or BOTH configurations. Modules will still
build in sys/modules/igb or em as before.
This also updates the igb driver for support for the 82576

This article [1] describes the -p flag for make(1):
Write to standard output the complete set of macro definitions and
target descriptions. The output format is unspecified.
We already support a similar flag (-d g1), but unlike -p, it still
executes commands. Our implementation just turns it into -d g1, but also
sets flag `printGraphOnly', which will cause make(1) to skip execution.
