and Daichi GOTO <daichi@FreeBSD.org> for submitting this
major rewrite of unionfs. This rewrite was done to
try to solve many of the longstanding crashing and locking
issues in the existing unionfs implementation. This
implementation also adds a 'MASQUERADE mode', which allows
the user to set different user, group, and file permission
modes in the upper layer.

mii_phy_match() API and takes care of the PHY device probe based on
the struct mii_phydesc array and the match return value provided.
Convert PHY drivers to take advantage of mii_phy_dev_probe(),
converting drivers to provide a mii_phydesc table in the first
place where necessary.

- Currently LINUX_MAX_COMM_LEN is smaller than MAXCOMLEN, but in case
this will change we have a buffer overflow. Apply some defensive
programming to DTRT when this should happen.
- Use copyinstr() instead of copyin where appropriate.
* Fallback to copyin() in case of ENAMETOOLONG. [1]
* Use the right source and destination (it was wrong before).
- Use strlcpy instead of strcpy.
- Properly lock the read case (PR_GET_NAME) like the write case.

on the arm. Add an assert to ensure that the size is 8 to prefent others
from falling into this trap (we should have more of these).
Why the construct:
struct foo {
union bar {
struct {
...
} __packed fred;
...
} __packed wilma;
} __packed;
has a different packing than:
struct foo {
union bar {
struct {
...
} fred __packed;
...
} wilma __packed;
} __packed;
is beyond my ability to ferret out of the gcc documentation. Most
likely some subtle binding issue (eg before it says the struct itself
is packed, while after it means that the whole struct is packed into
the thing it is in). Pointers to relevant documentation would be
appreciated.
sizeof ether_header is 2 * ETHER_ADDR_LEN + 2 (14) bytes long
sizeof ether_addr is ETHER_ADDR_LEN bytes long
On arm, this shows that struct ether_addr needs to be __packed.
The first condition muts be true for the bridging code to not dump core.
The second one appears to be implicitly relied upon by wi (but many
of the rids it sends down likely need __packed too to be safe) and
maybe others. It appears to not hurt anything.

missing braces around the initializer of each struct, which
triggers warnings in WARNS=3:

* Fix the sigconv.awk script to generate a header with initializers
which look better.
* Add rules to usr.bin/top/Makefile that rebuilds a new sigconv.h
header which matches the correct signal set from the build-time
version of `${DESTDIR}/usr/include/signal.h' (so sigconv.h doesn't
get stale once changes are made to the header).
* Remove the old sigconv.h header, now that it is autoupdated at
build time.
* Various Makefile style fixes (the committed Makefile was kindly
submitted by Ruslan):
- Reorder .PATH, PROG, SRCS and CFLAGS to match style.Makefile(5)
- Split off the generated sources (sigdesc.h top.local.h) in an
SRCS+= line of their own.
- Add entries to CLEANFILES near the rules that generate the
respective files.
- Move the explicit rule which builds top.1 after the implicit
rules which generate its dependencies.

Unfortunately we cannot do the same for output errors because ifOutDiscards

wrong BGE_RX_STATS/BGE_TX_STATS with BGE_MAC_STATS. They were reversed but
worked accidently.

The chip design is crazy -- on RX, it puts the 16-bit VLAN tag
in network byte order (big-endian) in the 32-bit little-endian

if_watchdog/if_timer interface doesn't fit modern SMP network
stack design.
Device drivers that need watchdog to monitor their hardware should
implement it theirselves.
Eventually the if_watchdog/if_timer API will be removed. For now,
warn that driver uses it.

__stop_<section> symbols generated by the static linker for elf
sections. This is done only for the final link, and not for ld -r.
Augment elf_obj in-kernel linker by recognizing such special symbols,
and resolving them to the start and end of the section automatically.
As result, linker sets on amd64 could be used in the same way as on
other architectures, without explicit calls to linker_file_lookup_set().
