If the call to _pmap_allocpte() is not sleepable, it is possible that
allocation of PML4 or PDP page is successful but either PDP or PD page
is not. Restructured code in _pmap_allocpte() leaves zero-referenced
page in the paging structure.
Handle it by checking refcount of the page one level above failed
alloc and free that page if its reference count is zero.

The proper procedure was not followed in r364943; all of these that were
deleted should have instead been moved over to the blacklist so that certctl
can DTRT.
Users must still `certctl rehash` after this, but this should generally be
done by one of mergemaster/etcupdate/freebsd-update/pkgbase already; note
that freebsd-update doesn't come into play for this particular update, as
these have not yet made it into a release.
Future work (after svn -> git) will likely change the script that updatecert
invokes to facilitate the process, rather than trusting that kevans or
whomever updates in the future will remember.

Allow architecture names to be passed in to the build system via CPUTYPE.
This allows the user to use values such as armv8.1-a or armv8-a+crc as
the CPUTYPE.

We must enter NET_EPOCH before calling ether_output_frame(). Several of the
functions it calls (pfil_run_hooks, if_transmit) expect to be running in the
NET_EPOCH.
While here remove an unneeded EPOCH entry (which wasn't wide enough to cover
BRIDGE_INPUT).

Make sure that building dev/sdhci/sdhci_fsl_fdt.c has all the right
dependencies until a proper fix can be made.

The CS_DRAIN flag cannot be set at the same time like the async-drain function
pointer is set. These are orthogonal features. Assert this at the beginning
of the function.
Before:
if (flags & CS_DRAIN) {
/* FALLTHROUGH */
} else if (xxx) {
return yyy;
}
if (drain) {
zzz = drain;
}
After:
if (flags & CS_DRAIN) {
/* FALLTHROUGH */
} else if (xxx) {
return yyy;
} else {
if (drain) {
zzz = drain;

Energy Efficient Ethernet (EEE):
- introduce new device ids
- add ability to select 2.5 and 5G speeds on devices which support it
- add sysctls to enable EEE and read related statistics
