bsd.init.mk ends up including defs.mk so the per-arch options must be
set before including defs.mk, or else the global defaults will be
used and the per-arch ones will be ignored.
Although better, note that the usage of MK_FDT before the inclusion of
bsd.init.mk is incorrect but doesn't lead to build errors. This
circular dependency must be broken in order for this to work
correctly.

Compared to the previous version, v0.16, there are a couple of minor
changes:
- CLOUDABI_AT_PID: Process identifiers for CloudABI processes.
Initially, BSD process identifiers weren't exposed inside the runtime,
due to them being pretty much useless inside of a cluster computing
environment. When jobs are scheduled across systems, the BSD process
number doesn't act as an identifier. Even on individual systems they
may recycle relatively quickly.
With this change, the kernel will now generate a UUIDv4 when executing
a process. These UUIDs can be obtained within the process using
program_getpid(). Right now, FreeBSD will not attempt to store this
value. This should of course happen at some point in time, so that it
may be printed by administration tools.
- Removal of some unused structure members for polling.
With the polling framework being simplified/redesigned, it turns out
some of the structure fields were not used by the C library. We can
remove these to keep things nice and tidy.

similar to the kernel memory allocator.
This simplifies NUMA allocation because the domain will be known at wait
time and races between failure and sleeping are eliminated. This also
reduces boilerplate code and simplifies callers.
A wait primitive is supplied for uma zones for similar reasons. This
eliminates some non-specific VM_WAIT calls in favor of more explicit
sleeps that may be satisfied without new pages.

Summary:
Existing code recognizes the mcp7941x RTC, but this RTC has an
enable bit at the same location as the "Clock Halt" bit on the ds1307, with an
opposite assertion (set == on, whereas CH set == clock stopped). Thus the
current code halts the clock, with no way to enable it.

According to EREF rlwinm is supposed to clear the upper 32 bits of the
register of 64-bit cores. However, from experience it seems there's a bug
in the e5500 which causes the result to be duplicated in the upper bits of
the register. This causes problems when applied to stashed SRR1 accessed
to retrieve context, as the upper bits are not masked out, so a
set_mcontext() fails. This causes sigreturn() to in turn return with
EINVAL, causing make(1) to exit with error.
This bit is unused in e500mc derivatives (including e5500), so could just be
conditional on non-powerpc64, but there may be other non-Freescale cores
which do use it. This is also the same as the POW bit on Book-S, so could
be cleared unconditionally with the only penalty being a few clock cycles
for these two interrupts.
The problem with it was a bogus .OBJDIR in some cases where creation of
object directories were purposely not attempted, such as for 'make cleandir'
and in etc/ sub-directories. In these cases bmake would start with a
bogus .OBJDIR like etc/ due to MAKEOBJDIR being a dynamic value based on
.CURDIR, SRCTOP, and OBJTOP. OBJTOP would not yet be defined but is
during early src.sys.obj.mk. That file and auto.obj.mk both were not
modifying .OBJDIR unless they expected to create the objdir. Thus in
these cases the .OBJDIR was left as etc/* rather than fixed to the
proper .CURDIR.
The issues were fixed in r325404 and r325416. An assertion to avoid the
bad .OBJDIR was added in r325405.

The patch contains following changes:
* In conditional checks, always check for NULL or 0 instead of negating values
* Use malloc and free explicitely, instead of ENA_MEM_FREE and ENA_MEM_FREE (the
dmadev passed to macro is never used, and could be a little misleading)
* Always check for NULL after calling malloc (few checks were missing)
* Rework naming of the goto tags in ena_attach() for consistency
* Fix error handling in ena_attach() - few goto instructions were leading to the
wrong tag
* Destroy MMIO req read request if attach failed
* Remove checking for NULL after calling malloc with M_WAITOK flag

Provide new control message SCM_TIME_INFO to supply information about
timestamp. Currently it indicates that the timestamp was
hardware-assisted and high-precision, for software timestamps the
message is not returned. Reserved fields are added to ABI to report
additional info about it, it is expected that raw hardware clock value
might be useful for some applications.

boot for the received packets.
The rcv_tstmp field overlaps the place of Ln header length indicators,
not used by received packets. The basic pkthdr rearrangement change
in sys/mbuf.h was provided by gallatin.
There are two accompanying M_ flags: M_TSTMP means that there is the
timestamp (and it was generated by hardware).
Another flag M_TSTMP_HPREC indicates that the timestamp is
high-precision. Practically M_TSTMP_HPREC means that hardware
provided additional precision comparing with the stamps when the flag
is not set. E.g., for ConnectX all packets are stamped by hardware
when PCIe transaction to write out the completion descriptor is
performed, but PTP packet are stamped on port. For Intel cards, when
PTP assist is enabled, only PTP packets are stamped in the limited
number of registers, so if Intel cards ever start support this
mechanism, they would always set M_TSTMP | M_TSTMP_HPREC if hardware
timestamp is present for the given packet.
Add IFCAP_HWRXTSTMP interface capability to indicate the support for
hardware rx timestamping, and ifconfig(8) command to toggle it.

Preserve packet order between tcp_lro_rx() and if_input() to avoid
creating extra corner cases. If no packets can be LROed, combine them
into one chain for submission via if_input(). If any packet can
potentially be LROed however, retain old behaviour and call if_input()
for each packet.
This should keep the 12% improvement for small packet forwarding intact,
but mostly avoids impacting the LRO case.

Steal the code from kmod.mk and use it to automatically create
links. Modify it a little for the needs of the loader (no need to
guess the OBJS dependency, and we have 32-on-64 cases to contend
with). Remove 15 redundant implementations (which were mostly
different, but kinda the same).
A future commit should factor out this code and that of kmod.mk so we
have only one copy of it in the tree.
